The dusty file of the "Nine Sections of the Flying Man" case

One

　　A "Trident" passenger plane flew over the boundary of Shanghai and began to descend in altitude to prepare for landing.

　　The Chinese civil airline, which was flying from Guangzhou to Shanghai, was carrying 96 Chinese and foreign passengers on board. When they listened to the "Please fasten your seat belt" announcement from the flight attendant in Chinese and English from the loudspeaker in the cabin, they reacted one after another, some whispered to each other, some checked their tickets to claim their luggage in time, and those sitting at the window looked out to see the fields, rivers, and farmhouses on the ground full of Jiangnan characteristics. The two young men sitting alone in rows A and B behaved differently in that they did not look out of the portholes, nor did they talk to each other, nor even move their bodies, but sat in their seats and waited for the plane to land.

　　These two very calm men, one is named Ye Jiadong and the other is Mai Xingguan, and they are Interpol from Hong Kong.

　　Half a month ago, there was a jaw-dropping theft case in London, England, where a young engineer named Lenny Decigo had mastered Ding's technology of deciphering computer security codes after years of research. A home computer, a telephone, and his patience beyond ordinary people easily transferred 2,500,000 pounds from the National Bank to his account, and by the time the bank found out that 2,500,000 pounds had been found in the account, Lenny De Cicgo had already taken the huge amount away. He used a pseudonym on his account, so National Molybdenum investigators were unable to track him down and had to file a police report.

　　It took a lot of effort for the computer experts at Scotland Yard to find out the wavelength at which the order had been given to draw a huge amount of money. So several monitors were set up to monitor day and night, and three days later, it was finally determined that the wavelength was sent by Lenny D'Isic, that is, this technology. He was responsible for the theft. However, at the same time that the computer experts at Scotland Yard captured the wavelength, Lenny Dixigo had already noticed it, and immediately left his apartment for the airport and fled the United Kingdom. INTERPOL Headquarters immediately issued an order to the branch of the country concerned (known as the "Interpol × Bureau") to investigate the whereabouts of Lenny D'Ducigo and arrest him. France, West Germany, Iceland, Denmark, the Netherlands and other countries have taken urgent action against Interpol, but they have not been able to arrest the culprit, and only got clues that Lanny and Diego may have fled to Hong Kong.

　　The Interpol headquarters then telegraphed the Hong Kong Bureau for an urgent investigation. After several days of investigation, Hong Kong's Interpol found no trace of Lenny Dixigo, and found only one clue: a Chinese woman named Zhong Jiexiang was the concubine of the criminal, and in the past few days, she had shared a luxurious suite in a large hotel with a British man who looked like the criminal. The head of the Hong Kong Bureau of the Guoyong Criminal Police ordered: Make every effort to find Zhong Jiexiang and get clues about Lenny Dixigo from her! The criminal police checked down and learned that Zhong Jiexiang had gone to Chinese mainland to visit relatives, and her visa was valid for three months.

Hong Kong's Interpol was stunned: Three months, three months later, the clues provided by Zhong Jiexiang will still work, wow? No, we have to find her immediately!

　　China is already a member of Interpol, and Hong Kong only needs to contact the Interpol China Bureau in Beijing, and the Chinese police will immediately find Zhong Jiexiang and inform Hong Kong of the clues obtained. However, it was September 1974, and China had not yet joined Interpol, so it had neither an organization nor an obligation. Of course, there are cases where the police of countries that are not members of Interpol assist other countries in solving crimes, but the Hong Kong police did not dare to open this mouth to China, because at that time, China's "Cultural Revolution" had not yet ended, and everything was surprisingly "leftist". In desperation, the Interpol Hong Kong Bureau had no choice but to send people to Chinese mainland to find Zhong Jiexiang to collect evidence, and the head of the bureau named Ye Jiadong and Mai Xingguan, and assigned these two backbone cadres to the mainland (mainland) to carry out this special mission.

　　In China at that time, Hong Kong was an untouchable capitalist world. Most Chinese people (including the police) like to look at people through colored glasses, and regard people from Hong Kong as "people from overseas" in domestic anti-special films. If it was the police of the past two capitalist worlds, it would have been okay, but I am afraid that Ye Jiadong and Mai Xingguan would have been expelled before they found Zhong Jiexiang. The Hong Kong police were worried about this, so they allowed Ye and Mai to enter the country under the guise of businessmen going to the mainland to purchase medicines.

　　Ye Jiadong and Mai Xingguan went to Guangzhou from Hong Kong, and with the skills of criminal police, they found out in a hotel that Zhong Jiexiang only stayed in Yangcheng for one night and then went to Shanghai, so they immediately flew to Shanghai. When the two of them stepped down the ramp of the plane and stepped onto the runway of Hongqiao Airport, they felt very relaxed in their hearts, thinking that completing the mission was an easy task.

　　Ye Jiadong and Mai Xingguan walked out of the airport ticket gate and got into a "Shanghai" taxi. The driver asked where to go, both of them had never been to Shanghai, and they didn't know which hotel to go to, so they looked at each other, and Mai Xingguan said: "Find a hotel close to the city center and more convenient to go to all parts of the city!"

　　"Then go to Huajiang Hotel, shall we?"

　　"It's good!"

　　After the two Interpols arrived at the Huajiang Hotel, they quickly completed the accommodation procedures, and the receptionist at the general service desk provided three rooms on the first floor, the third floor, and the sixth floor for them to choose, perhaps for safety reasons, or also Hong Kong's unique Xi of Chongxin meeting "6" and Shun (66 Shun) and "8" Bifa (the homonym of eight is close to "fat"), and chose the room in Liufu. After the two put away their simple luggage, they immediately plunged into the investigation. According to the information provided by the relevant departments of the Hong Kong Police Force, Ye Jiadong first reported the address of Zhong Jiexiang's relatives to the "115 Channel", which specializes in inquiring about the paging telephone, and requested to inquire about the paging telephone number of the household, and then called directly after receiving an answer. The person who answered the phone was Zhong Jiexiang's aunt, who told the Cantonese-speaking man who claimed to be Zhong Jiexiang's "classmate": Zhong had arrived in Shanghai, lived in the Shanghai Building, and had gone to Suzhou and Wuxi to play today, and would return to Shanghai the day after tomorrow.

　　Ye Jiadong and Mai Xingguan discussed it and decided to rush to Wuxi another day to find Zhong Jiexiang. The two of them immediately went to the main desk to book train tickets. After doing all this, it was already 6 o'clock in the afternoon, and the two went to the restaurant for dinner, which was autumn, when the Qingshui hairy crabs were on the market. Ye and Mai were overjoyed when they saw the price marked on the menu: It was actually 90 percent cheaper than that in Hong Kong! Immediately they ordered Shaoxing Huadiao wine, steamed crab and a few crab dishes, took a big meal, drank six or seven points of drunkenness, and returned to the room satisfied. The two drank some tea, watched a little tasteless TV, took a hot shower, and went to bed.

　　Nothing to say for a night. Ye Jiadong and Mai Xingguan woke up, and the sky was already bright. The sunlight came in through the window, sacrificing a piece of light on the grass-green carpet, reflecting the green all over the room, Mai Xingguan turned over and got out of bed, and suddenly intuitively felt that something was wrong in the room, and his mouth continued to say "Hmm", turning around the room. After a moment, I suddenly pulled open the bedside table drawer, and I couldn't help but be surprised - the wallet and watch that I put in before going to bed last night were gone!

　　Ye Jiadong immediately opened the bucket in front of his bed and looked at it, and his mouth couldn't help but cry out one after another: The wallet, watch and gold ring were stolen!

　　A small part of the travel expenses brought by the two of them were kept in their wallets, and most of them were hidden in their travel bags. While muttering, "I only knew that the 'Cultural Revolution' in the mainland was powerful, but I didn't expect thieves to be so powerful", he opened the closet with the key to check, and the box was still there, so he let out a long breath: "Oh-it's okay!

　　The two Interpols put on their clothes and did not bother to wash themselves, but first studied a question: How did the burglars enter the room? The two of them used their housekeeping skills to investigate the scene, first inspecting the carpet, on which no footprints were found, and then looking at the handle of the drawer, the naked eye could not see anything famous because there was no chemical agent or magnifying glass to display fingerprints. Ye Jiadong walked to the window, pointed to an open window, and asked his companion, "This window was open last night?"

　　Mai Xing thought about it and said uncertainly: "It seems that we drank last night and didn't pay attention to such details." However, it doesn't matter if the window is open or closed, this is the sixth floor, and it is impossible for anyone to climb the meter. ”

　　Ye Jiadong pointed to half a footprint on the windowsill: "What is this?"

　　Mai Xingguan took a closer look, blinked in amazement, leaned out of the window and looked down, below was the backyard of the hotel, where a long sedan and jeep were parked, and the colored cement walls were so light that it was impossible to climb at all; the height of a six-story building was impossible to climb with a whisk. Unless a fire ladder is used, this is obviously unrealistic and impossible. As soon as Mai Xingxian said the reason, Ye Jiadong felt the same way. So, the two came to the conclusion that the thief used the key to unlock the door and then came in through the door? After the crime was successful, he printed shoe prints on the windowsill, so Mai Xingguan frowned and said with a wry smile: "Man, this is a mainland thief showing us his skills...... What should I do?"

Ye Jiadong pondered for a moment and said, "Let's take an inventory of what we have taken first!"

　　After counting, it was found that the following money and goods were stolen: HK$1,500, RMB325, two watches, a gold ring and two passports.

　　Two

　　For the Chinese people at that time, the passport did not show the purchase of grain and briquette cards. However, the passport has an unusual meaning for Ye Jiadong and Mai Xingguan, the passport is their "international ID card", with a "photo" to travel all over the world, without a "photo" it is difficult to move an inch, without the "ID card", they can not cope with the possible interrogation of the Chinese police, or even if they do not check, they will not be able to settle the bill and leave the hotel where they stay, let alone return to Hong Kong!

　　The problem suddenly became serious: they had an important secret mission, and if they reported the crime, they would have to tell the Chinese police the whole situation. And if the Chinese police do not believe their statements and examine them as suspected agents of the Taiwan Special Agent and the KGB? And if they do not report the case, they will not be able to leave Shanghai, let alone carry out their mission. They are now in a difficult situation!

　　The two discussed for a while, and in desperation, they came up with a solution: ask the British Consulate in Shanghai for help!

　　Because they did not have passports, they were unable to enter the consulate through the Chinese armed police posts set up at the British Consulate, so they "had no choice but to use the telephone, but they were cautious, saying only that they were Hong Kong public servants and that they had encountered unexpected difficulties when they came to the mainland to carry out official duties, and asked the consulate to send someone to negotiate with them as soon as possible."

　　Half an hour later, a third-class secretary of the British Consulate came to the Huajiang Hotel and knocked on the door of the Interpol. Ye Jiadong and Mai Xingguan first revealed their identities and special missions to the visitors, and then told them about the theft at night, asking the consulate to try to help them solve this problem. The secretary wrote down the situation in the official car what the two men had said, and the mission of his trip was only to understand the situation, and he had no power to deal with it, and how to deal with it had to go back and report it to the consul general. The matter was important and urgent, he didn't delay much, he left immediately, and asked Ye and Mai to stay in the room and wait for the phone when he left.

　　After a while, a call from the British consulate came, and the third-class secretary conveyed the opinion of Mr. Consul General to the two Interpols and reported the case to the police!

　　Ye Jiadong and Mai Xingguan had nothing to do, so they had to call the head of the hotel's security section, inform him of the situation, and ask him to report the case to the management.

　　The security section chief's surname is Yang Minggang, a company commander who has been transferred from the army, with a tiger's back and a bear's waist, and a big man, an "old tank" "squeaked and groaned all the way to the Huajiang Road police station" under his crotch, and almost fell apart. Yang Gang walked into the courtyard of the police station and saw the director Chen Jiaxiong standing in the courtyard smoking a cigarette, so he bluffed loudly:

　　"Director Chen, it's terrible: the ...... of the Huajiang Hotel guests have been stolen"

　　Chen Jiaxiong is 36 years old, which is the age when he speaks vigorously and lifts his feet like a wolf and a tiger. He likes to be alone and think about problems? Today, he was pondering a long-unsolved roadblock rape case, and when he saw that his thoughts were about to "enter the port," he was unexpectedly interrupted, and when he looked back, it was Yang Gang, and it was inconvenient to have a seizure, so he just frowned and said: "I was shouting nonsense early in the morning, and there was not a murder case! What is the matter? Let's go into the house and talk about it." ”

　　Yang Gang followed Chen Jiaxiong into the office and told him about the theft of Ye Jiadong and Mai Xingguan.

　　The policeman Xiao Liang said on the side, "The dignified Huajiang Hotel was stolen, what are you doing in the security department!"

　　Yang Gang is a well-known "Yang Cannon" in the army, and he has only been the chief of the security section for two months after he has been transferred to another job, and he has not yet been connected with the police station, of course, there is no friendship to talk about, and when he heard Xiaoliang say this, he immediately retorted: "The bustling city, the prime location, and the bad guys are so rampant at first glance, it is all because of your lack of contribution as a policeman!"

　　Xiao Liang still had to not give an inch to attack, but was stopped by Chen Jiaxiong's gesture. Before Chen Jiaxiong became the head of the police station, he served as the deputy head of the criminal investigation team of the public security bureau for six years. At first glance, Chen Jiaxiong has fine skin and white flesh, is thin and weak, wears a pair of wide-framed glasses, and has a gentle appearance, but in fact he is very fierce. He has been a criminal policeman for 4 years, and he has passed countless vicious cases under his hands, including three or four murderers. However, now that he has been promoted to the director of the police station, he is at the level of an authentic and serious department, which is just enough to reach the level of "a gentleman who talks but doesn't do anything", and is fully qualified to just lift his lips and let the police under him handle the matter. He said to Yang Gang: "Section Chief Yang, you are here to report the case, not to discuss the division of responsibilities and responsibilities in place, so don't talk about gossip." The hotel was stolen, and although the amount was not very large, I always had to send someone here. Regardless of whether the case is solved or not, the police station will definitely make every effort to do it. I arranged for a person, who, like you, also came down from the army, and his level was not higher than yours, and he was at the battalion level. After speaking, one turned around and walked to the window, opened his voice and shouted into the courtyard: "Du Yuanguo!

　　"Listen!" A man wearing a snow-white shirt, a fuchsia wool vest, a shiny face, and spotless all over his body, just like a common overseas guest in Huajiang Hotel, stood behind Chen Jiaxiong and promised, Du Yuanguo, 35 years old, is a well-looking and clean, and he is a refreshing man standing anywhere. He became a soldier at the age of 18 and mixed up to the battalion level in the naval intelligence department, and he could probably have developed, but he later offended a top boss and quarreled every now and then. was originally placed in a factory to be the secretary of the party branch of the workshop, Du Yuanguo refused to live or die, and after several struggles, he finally entered the public security organ and found a position as a field team leader at the Huajiang Road Police Station. In terms of level, this position is equivalent to a squad leader in the army, but Du Yuanguo is already satisfied.

Chen Jiaxiong said: "Since you have heard it, I will not be verbose. You take a few guys to 'Huajiang' for a trip, I listened to Section Chief Yang's introduction, this case is mostly of the nature of internal theft, you go there to make a good repair, make all the strength of breastfeeding, and you must drum that kid out." ”

　　Yang Gang saw that the police station only sent two policemen out of the scene, and he was quite unimpressed, and reminded him: "Director Chen, the owner is Interpol!"

　　Chen Jiaxiong said: "By the way, Du Yuanguo, after you have inspected the scene, call the Foreign Affairs Office of the Municipal Bureau and tell them about the situation, and the Interpol kicked the ball to them." ”

　　Du Yuanguo took the policeman Xiao Cai to the Huajiang Hotel, and the two Interpols couldn't help but be a little disappointed when they saw two Interpols coming. Hong Kong has a lot of money and a lot of policemen, and when it comes to this kind of robbery, it will be at least half a dozen people, and it will be equipped with police dogs and cameras. The 20 Chinese policemen in front of him only brought a hand-held survey helmet and a broken camera (this was the only one at the Huajiang Road Police Station), can this solve the case? Looking at Du Jinguo's movements again, it seems that he is not very skilled, so he guesses that this old man may be a monk halfway through the family and a new police meal. Ye Jiadong and Mai Xingli glanced at each other, and after answering Du Yuanguo's question, they simply walked out and stayed in the corridor. They have no hope of solving the case, and only hope that the Foreign Affairs Office of the Municipal Public Security Bureau will solve the problem of stolen passports.

　　Du Yuanguo and Xiao Cai investigated the scene, and after analysis, they also believed that it might be an internal theft case, and the perpetrator entered the scene through the door. As soon as they said to the head of the security section, Yang Gang nodded his head and said, "What you see is slightly the same." The three of them discussed it and decided to immediately set about doing an internal investigation of the hotel.

　　At this time, two policemen came to the Foreign Affairs Office of the Municipal Public Security Bureau, and after inquiring about the situation of Du Yuanguo and two Hong Kong residents, they contacted the British Consulate and asked them to issue a document certifying the identities of Ye Jiadong and Mai Xingguan, which was stamped by the Foreign Affairs Office and temporarily used as a certificate within the scope permitted by the mainland's regulations; as for passports, there is no guarantee that the case will be solved and recovered in a timely manner, so the consulate must be responsible for contacting the Hong Kong side and then reissuing and mailing them to the Hong Kong side. Ye Jiadong and Mai Xingguan are on a mission, and the Shanghai police can assist them in handling it.

　　After the city police left, Du Yuanguo, Xiao Cai, and Yang Gang went into the office of the security department and held a case analysis meeting. According to the information obtained from the on-site investigation, no pry marks were found on the door and keyhole, which indicates that the perpetrator entered the scene by opening the door with a key. The first thing to find out is who has the keys to the house or have access to them, and then to identify them from among them.

　　Each room of Huajiang Hotel has two keys, one is in charge of the floor service desk, and the other is in the charge of housekeeping, which is locked in a safe in the director's office. Du Yuanguo went to visit the chubby director of housekeeping. This benevolent brother was annoyed by the burglary in the guest room, and said bitterly: "I have been the director of the housekeeping department for 9 years, and there has never been a case of theft! Alas, the reputation of 'Huajiang' is very ugly......

　　After Du Yuanguo calmed him down, he understood what he meant. The fat director patted the keychain hanging on his waist by the general's belly: "The key to the safe is here with me, day and night, I don't want to use my brains! As for this safe, it is in the back room, you know, outside my office is the general service desk, and there are people 24 hours a day, and no one has a chance to pry it." As soon as I got to work in the morning, I heard that something had happened, and immediately went to see the key, and there was no missing!"

　　After the fat director finished speaking, he asked Du Yuanguo to go to the back room to check his safe. Du Yuanguo didn't go, because if any thief had the ability to pry open the safe, he would never pry open the safe and take the key to the door and then open the guest room door to steal, it would be better to pry the bank safe directly.

　　When Du Yuanguo visited the director of the housekeeping department, Xiao Cai and Yang Gang were talking to the waiters in the office. The waiters at the Huajiang Hotel work in two shifts, and when the two Interpols discovered the theft this morning, the night waiters had not yet left work. When the security department received the report, its first response was to inform the two waitresses on the night shift at the service desk on the sixth floor not to leave after work and wait for the investigation. These two waiters are around twenty-seven or eight years old, and have been working in "Huajiang" for 10 years, and they have never had a mistake in controlling the key with confidence, so they are calm and calm in the face of the police's questioning, according to them, the guest room key is usually locked in the drawer when not in use, and there is only one key to the drawer. As for last night, the two of them have been together all the time, and they can testify to each other, and besides, they have not left the store since they entered the hotel to work, and they have not even left the floor, so they can fully withstand investigation.

　　Xiao Cai learned from Yang Gang that the two waiters were party members and had always behaved very well, and judging from the looks of the two, he believed that they had nothing to do with the case, so he asked them to go home from work.

　　Then, they talked to the day attendant, but they found nothing suspicious.

　　After tossing for a long time, but with no gain, "Yang Cannon" was greatly annoyed and cursed: "Fuck! This case is annoying, how long do you have to toss?"

　　Du Yuanguo patted him on the shoulder like an old friend: "Man, if you can solve a case in half a day, why does the Public Security Bureau have to raise so many policemen?"

　　Yang Gang glared: "What should I do about this?"

　　"Check again! I don't believe I can't find clues!"

　　In the afternoon, Du Yuanguo went back to the police station, reported the situation to Chen Jiaxiong, and asked for advice. Chen Jiaxiong said: "If you check in the direction you have agreed, everyone who can touch the key."

Everyone checks it out, maybe there are clues worth it for you to leisurely cross Erlang's legs and drink two taels!" Du Yuanguo returned to Huajiang Hotel, discussed with Yang Gang, Xiao Cai and the fat director of the customer department, made a small blackboard, and wrote a name on it when he thought of a person. When he wrote about the last one, He Jingen, the fat director slapped his forehead and shouted, "Yes! This kid is suspicious!"

　　Du Yuanguo and Xiao Cai were suddenly in high spirits, and even asked what was going on. So, Director Fat introduced the situation: He Jingen, 24 years old, a hotel repairman, has conditional access to the key to the guest room. This person usually behaves averagely, is said to have gambling behavior, and recently heard that he has "finalized" a girlfriend, is ready to get married, and came to the office to borrow money for two months.

　　Xiao Cai said: "I have handled many cases of defying the law in order to raise money for marriage, and this person is indeed suspicious!"

　　Du Yuanguo said: "If you are suspicious, first check what he was doing last night before drawing conclusions." ”

　　He Jingen works as a repairman, and he works a regular shift, and Yang Gang arrives as soon as he is called. This is a tall and medium-sized man with a pair of dripping eyes on his long melon face, and at first glance he knows that he is a delicate and clear horn.

　　Yang Gang asked him to sit down, and said with a calm face: "He Jingen, you are responsible for maintaining the water and electricity facilities in the guest rooms on the fifth and sixth floors?...... Have you taken the key to room 605 lately?"

　　Of course, He Jingen knew what it meant to ask "605", how could he be suspicious of this melon field and plum, so he shook his head again and again, and admitted: "It's okay! The hotel has a rule that repairmen can't take the key to the guest room." ”

　　"Regulations are regulations, and it's one thing to enforce them or not!"

　　"I really haven't taken it!"

　　Yang Gang Qiufeng shouted with a black face: "Okay, you kid, you won't admit it if you don't spread the evidence in front of you!" He threw over a piece of circumstantial evidence written by the fat director who asked the day attendant on the sixth floor, "He Jingen, take a look, the key you went to the service desk to get when you went to 605 to repair the pumping horse on the afternoon before the National Day!"

　　He Jingen's face suddenly changed completely, and he hung his head and was silent. At this time, Du Yuanguo opened his mouth: "He Jingen, what were you doing last night?"

　　"I ...... I go to someone's house to play...... No...... No! Let me think, by the way, I went to the movies! I went to an all-night show, from 9 o'clock in the evening to 4 o'clock in the morning. As he spoke, as if to confirm this, he opened his mouth and yawned a few times.

　　Du Yuanguo was unmoved, thinking that if he had to sleep for most of the night when committing the crime, this yawning would also apply, so he asked, "Which movie theater?"

　　"Tarzan. ”

　　"What's on it?"

　　"Coastal Wind and Thunder", "Crossing the River Reconnaissance", "Guerrillas on the Plains", "Tunnel Warfare", and several "News Bulletins". ”

　　Yang Gang immediately went to the next room to call and inquire, and when he returned, he looked proud, "hummed" in his nose, and sneered so much that He Jingen's face was white and blue. Du Yuanguo immediately understood what was going on, and asked, "He Jingen, how is it, do you want to get a car to pull you to the door of the Taishan Cinema to look at the poster?"

　　“……”

　　Xiao Cai patted He Jingen on the shoulder: "Let's be honest, what did you do last night?"

　　"Watch a movie!,

　　"Still 'watching a movie'?" Du Yuanguo was furious, "Okay! I invite you to go to the police station to 'watch a movie'!"

　　The Huajiang Hotel sent a car to take He Jingen to the police station. Generally speaking, guys who have never dealt with the police station and have done bad things often can't withstand the "three axes" of the police when they enter the police station. Don't look at He Jingen's face is blue and white, looking vulnerable, but he is more capable than some "second palace" and "third palace". He sits

In the interrogation room of the police station, I insisted that I was watching an all-night movie last night, and as for the title, I can't remember it, because I drank alcohol and dozed off in the movie theater all night. No matter whether Du Yuanguo is sweet or threatening, he always puts on a look of "real gold is not afraid of fire".

　　Interrogation was suspended. Du Yuanguo and Xiao Cai visited He Jingen's house to learn about He's whereabouts last night. He Jingen's parents said that after their son went out after dinner last night, he did not return overnight. This testimony is valuable for suspecting He Jingen of committing the crime, but it is not helpful for interrogation.

　　The two returned to the police station, and Chen Jiaxiong went to report. Chen Jiaxiong was about to get off work, he had already changed into civilian clothes, and when he heard this, he put on a police uniform on his body again: "It seems that I want to be arraigned by the director? This guy has a big face!"

　　Halfway through the police uniform, someone outside begged to see Director Chen. Chen Jiaxiong asked the police on duty to let the seekers in, and when they saw that they were young men of 27 or 8 years old, who claimed to be workers at the welding machine factory, to provide information. Chen Jiaxiong frowned and asked, "What's the situation?"

　　The man had come to testify against He Jingen. It turned out that he was the elder brother of He Bogen's fiancée Zhang, and yesterday was his sister's birthday. Before getting off work today, Zhang went to the Huajiang Hotel to call He Jingen, only to know that his fiancé was suspected of being suspected of theft last night and entered the police station, thinking that the fiancé was unwilling to confide in her face last night, thinking that this was not a joke, so he begged his brother to come to the police station to explain.

　　When Chen Jiaxiong heard this, he asked angrily: "What about your sister? Why didn't she come herself?"

　　"She's thin-skinned and embarrassed to come here. ”

　　Xiao Cai muttered on the side: "Thin-skinned?

　　Du Yuanguo said: "In this way, you write a situation, and we will deal with it as we do after the investigation." ”

　　Du Yuanguo and Xiao Cai investigated overnight, and He Jingen, Zhang and their families said the same. He Jingen was let go home that night.

　　Three

　　This night, He Jingen, who was in no danger, slept soundly, but Du Yuanguo couldn't sleep at all. He lay in bed tossing and turning from time to time, thinking about the case at hand. According to the investigation, the possibility of internal theft has been ruled out, but judging from the investigation of the scene, the perpetrator entered the scene through the door. So, apart from the insiders of the Huajiang Hotel, are there any other people who can enter the scene through the door? Yes - outsiders or other guests staying in the hotel. By the way, let's look it up from the perspective of these two people!

　　The next day, Du Yuanguo visited the lobby staff on night duty at the Huajiang Hotel and asked them whether there were outsiders entering or leaving the hotel on the night of the incident. Huajiang Hotel is a large hotel, and people come in and out every night. However, at that time, there was no nightlife in the society to entertain, so there were many outsiders in and out in the first half of the night, but there were almost no outsiders in the second half of the night, and some of them left in a hurry after midnight. At that time, all major hotels and hotels had a set of strict security systems, and all outsiders entering and leaving had to fill in the "guest list" and indicate the time of entry and exit. Judging from the situation described by the waiter on the sixth floor yesterday, they have been staying at the service desk in the first half of the night, and it is impossible for the perpetrator to commit the crime, so all the outsiders will not be the perpetrators.

　　The possibility of outsiders committing the crime has also been ruled out, so in the end, only the clue of the hotel guest remains. Du Yuanguo and Xiao Cai asked Yang Gang to take the registration book of the guests staying in the hotel, and after browsing it, they couldn't see anything suspicious, so they had to ask the security department to recall the situation and provide clues to the night attendants on each floor.

　　This move seems to make sense. In the afternoon of the same day, someone reported a situation to Yang Gang, chief of the security section. According to her recollection, at about two o'clock in the morning on the night of the incident, she went to the main service desk in the lobby to pick up something, and met a guest on the seventh floor coming out of the elevator at the elevator entrance.

　　As soon as Yang Gang said to Du Yuanguo, Du Yuanguo was interested, and immediately summoned Xiaomei, said a few words of encouragement, and asked, "What room does this guest stay in?"

　　Xiaomei said: "He just said to open the door, but he didn't say which room door to open, I can't remember clearly, it was Xiao Xu who opened the door."

　　"Xiao Xu is not in class today?"

　　"No. She went on a trip with her boyfriend after work yesterday and won't be back until five days later. ”

　　Du Yuanguo thought that he could only pin his hopes on the girl in front of him, and said: "That guest lives on the seventh floor, you are a waiter on the seventh floor, you must remember which room he lives in, think about it." ”

But Xiaomei couldn't think about it, it turned out that she had just been transferred from the fourth floor to the seventh floor on the day the case occurred, and she was doing the night shift again, and she didn't do services such as cleaning the room, so she was not familiar with the guests.

　　Du Yuanguo asked the section chief of the guard: "Is there any way to figure out this problem?" Yang Gang looked at his watch: "Another hour, it is the time to avoid the water, let Xiaomei turn around room by room and recognize it." ”

　　"Why wait an hour, enter the boiling water in advance. ”

　　There are a total of twenty rooms on the seventh floor, Xiaomei sent boiling water down, and half of the guests were not there, but the one she wanted to identify happened to have never gone out, so she recognized it - living in room 704.

　　It was learned from the passenger registration book that the guest in room 704 was named Qi Zengtian, 49 years old, an agronomist at an overseas Chinese farm in the suburbs of Nanning, Guangxi, who had come to Shanghai for personal business - to visit relatives and friends, and had been staying at the Huajiang Hotel for five days.

　　Isn't it too generous for an agronomist on a farm to come to Shangmei to do private business and live in an expensive "Huajiang" with a private room on the spot? Du Yuanguo and Xiao Cai discussed and decided to send a telegram to Guangxi to investigate Qi Zengtian's true identity while investigating the relevant situation on the spot.

　　Du Yuanguo asked Xiao Cai to send a telegram, and he went to the lobby to investigate whether he had seen such a guest in room 704 coming in from outside at about two o'clock the night before, and the answer of the staff on duty was no.

　　Yang Gang was excited when he heard this, and said to Xiaomei, "You go and ask him: What did you do when you went downstairs in the middle of the night before yesterday?"

　　Xiaomei went to the face, just went out and came in again, followed by the fat director of the housekeeping department, and the one behind him looked anxious, and shook his hand again and again: "Section Chief Yang, you can't mess around with the guests, you make a mistake and offend others, and the reputation of our 'Huajiang' will be ruined!"

　　Yang Gang was just about to speak, but Du Yuanguo opened his mouth and said: . In this way, Xiaomei found out in another way, saying that she had picked up something in the elevator the day before yesterday and asked if he had lost it. When he did, he would probably talk to himself about what he had gone downstairs the night before — whether it was true or not. If he tells a lie, it means that he has a ghost in his heart, and it is worth investigating deeply. ”

　　Xiaomei did as she said, and replied after a while: "He said that he went to the restaurant on the fourth floor the night before yesterday and wanted to have supper, and when he went in, he saw that there was no mess he liked to eat, so he went back to the room on the seventh floor." ”

　　I checked with the restaurant on the fourth floor, but no one over there remembered whether such a customer had ever entered the restaurant. However, Du Yuanguo couldn't make up his mind for a while whether he wanted to have a "face-to-face contact" with him. He thought about it for a long time and decided to wait until Guangxi came back to the phone.

　　At about 9 o'clock in the evening, an urgent telegram from the Nanning City Public Security Bureau came: After learning from the farm, it was found that Qi Zengtian was not the person.

　　Du Yuanguo said with a smile: "Now, you can contact Qi Zengtian face to face!"

　　Qi Zengtian was invited to the office of the Security Section. When he stepped into the door, he showed a look of bewilderment on his face, and asked without waiting for Du Yuanguo to ask, "It's so late, what are you calling me for?"

　　Du Yuanguo asked him to show his ID. Xiao Cai took his ID and looked at it, patting it to check whether it was true or not. Qi Zengtian regained his composure, explaining that he had been an agronomist at the farm and had resigned two years ago, but was still living in the farm's family dormitory. This explanation seems to be possible, but for the police, this topic is just an "entry point", at this time Du Yuanguo is not much interested in this, he is interested in the "605 theft", so he asked him about his whereabouts the night before.

　　Qi Zengtian showed a look of sudden realization on his face, and immediately repeated what he had said to Xiaomei before. Of course, Du Yuanguo had to move out of the restaurant staff to refute it, and this refutation made Qi Zengtian a "dumb", and he sat there smoking a cigarette and stopped talking.

　　At this point, it seems that Qi Zengtian should be given an environment. Xiao Cai pulled Du Yuanguo aside and offered to take the suspect to the police station for interrogation. Du Yuanguo had already learned the lesson of "white arrest" of He Jingen yesterday, and he was worried that it would be difficult to explain to Chen Jiaxiong if he "arrested him for nothing" again. If the police station takes a few innocent people in from time to time while arresting bad people, how can it be called "people's public security"? Therefore, he does not agree to "change the environment" for Qi Zengtian, but only advocates intensifying the "investigation." How can we increase the law? First, we sent a telegram to the Nanning side again to verify Qi Zengtian's true identity; and second, we tried to find direct evidence to prove whether Qi was a criminal or not.

　　Of the two, the former is easier to do, while the latter is quite difficult. No fingerprints were found at the scene, only half of the shoe prints on the windowsill, which were the marks of Jiefang running shoes, and Qi Zengtian was wearing leather shoes on his feet, and there were no other shoes in the room, which had nothing to do with him. Du Yuanguo thought about it and felt that there was only one way to search. Qi Zengtian only had one suitcase

, it was not locked, but when he opened it, it was all a change of clothes and daily necessities, and he emptied his pockets, and he did not find the money and goods stolen by Interpol.

　　At this time, it was midnight, and Yang Gang got a few suppers, one for each person, and one for Qi Zengtian. Du Yuanguo was eating supper, and suddenly remembered that when the on-site waiters cleaned the room after the survey yesterday, he had taken care of them to use a vacuum cleaner that had cleaned the dust box, and kept the things they had sucked intact. Yesterday, because I caught a glimpse of He Jingen, I forgot to check it, so why not take a look at it at this time, maybe I can find evidence.

　　In addition to dust and fibers, there is also a slightly curly hair more than an inch long, which is obvious to be male at a glance. Is this the criminal's or the guest's? Du Yuanguo immediately knocked on the door of 603. Although the money and property were stolen, there was no need to go to Wuxi, and the Shanghai police informed Zhong Jiexiang to return to Shanghai at their request, and they had already met this morning and obtained clues. The task is completed, and you can leave Shanghai and return to Hong Kong as long as the reissued passport is sent by the Hong Kong side. Du Yuanguo knocked on the door, showed his hair, and asked the two of them to identify whether it belonged to them. The two of them ate a police meal, and they were good at it, so they denied it at a glance, and they also gave several reasons. After saying a while, each person ripped off two of them from their heads and handed them to Du Yuanguo for identification.

　　The hotel room is cleaned with a vacuum cleaner every day, and since this hair is not owned by the two owners, it must be the perpetrator, and it cannot be the previous guest. After confirming this, Du Yuanguo went to compare with Qi Zengtian with his hair. In comparison, it was found that there was a clear difference: Qi's hair was thin and straight, yellow and dull, while the criminal's hair was thick and shiny and curly. Judging from this: Qi Zengtian is not a criminal.

　　On the morning of the next day, a second telegram from the Nanning City Public Security Bureau was sent: The results of the previous investigation were wrong, and there was indeed Qi Zengtian and his person at the scene, who had now left his post and was still living on the farm, and had recently gone to Shanghai to visit relatives and friends. While Du Yuanguo felt relieved that he had not "arrested" Qi Zengtian in vain, he also felt uneasy that the investigation work had been stranded.

　　Four

　　On October 16, 1974, five days after the theft at the Huajiang Hotel, another star-rated hotel in Shanghai, the Nanyang Hotel, also committed a theft.

　　At about half past 1 o'clock in the middle of the night, Li Lingzhen, a Chinese-American traveler staying in room 306 of the hotel, was awakened in her sleep by a slight "click" sound. She unconsciously opened her eyes slightly, and saw the window in a haze, and the black swan curtain at the mouth suddenly opened a crack, and a black shadow gently descended from the windowsill to the carpet!

　　At first, Li Lingzhen thought that she was still in a dream and wanted to open her mouth to call, but somehow she didn't make a sound. Then, when she felt that she could scream, she was too frightened to scream - she had already felt that this was reality and not a dream, that the shadow was really a person, and she could clearly smell and distinguish the fishy smell of the breath coming out of the man's mouth, which was the smell of artificially treated seafood. Li Lingzhen lay there, trying to keep her breathing calm, so that the uninvited guests thought she was asleep. She had seen a book in the United States on the criminal psychology of criminals, which warned readers that if the owner did not want to sacrifice his life to protect his property when a thief broke into a house at night, he should simply pretend to sleep and never make a sound, so as not to alarm the thief and make him decide to commit murder. Li Lingzhen has no room to play in the United States, but who knows that this time she has an opportunity to practice it in China.

　　Shadows moved silently around the room, sometimes by the bed, sometimes at the table, and pulling the closet door. After about five minutes like this, Li Lingzhen felt a fresh and cool air gently blowing on her face, realized that the thief jumped out of the window and left, and when she opened her eyes, there was indeed no shadow in the room, leaving only the faint smell of seafood. She didn't dare to turn on the lights, nor did she dare to make a phone call, for fear of alarming the thief and returning to kill someone. Ten minutes later, when she was sure that the thief must have fled, she called the main desk.

　　The Baxianfang Police Station, the public security jurisdiction agency in the area where the Nanyang Hotel is located, received a report, and Lu Guangming, the deputy director on duty, immediately brought two policemen under him to the Nanyang Hotel to investigate the scene. Lu Guangming listened to the statement of the frightened Li Lingzhen, checked the window sill, and found that there was a quarter of a shoe print on it, and two vague fingerprints were detected on the window frame, judging from the direction, it was left by the perpetrator when he entered the room. The trio went outside and downstairs to inspect again, but found no footprints, but it was confirmed that the perpetrator had climbed up from a water pipe on the wall to enter room 306.

　　Lu Guangming asked the owner to check what items were stolen. Li Lingzhen counted it and issued a lost report, totaling: 1,070 yuan, 2,000 US dollars, a gold necklace, a watch, and a bottle of "Dream Paris" high-end perfume (which has been opened and used).

　　The next morning, the Baxianfang Police Station reported the case to the substation. Song Bo, the head of the criminal investigation team of the sub-bureau, immediately remembered the theft case that occurred in the Huajiang Hotel five days ago, felt that there were similarities, and suspected that it was committed by the same criminal, so he notified the Huajiang Road Police Station and the Baxianfang Police Station to enter the footprints obtained from the on-site investigation into the sub-bureau for technical appraisal. The results were not long in coming: the two footprints were of the same person!

　　Chen Jiaxiong, director of the Huajiang Road Police Station, sighed when he heard the news: "Mistake! Mistake: There are footprints on the windowsill! Alas, what a self-inflicted cleverness!"

　　The sub-bureau decided to investigate the two cases simultaneously, and the Huajiang Road Police Station, the Baxianfang Police Station, and the criminal mission team of the sub-bureau each selected two people to form a special investigation team. Chen Jiaxiong volunteered to go out in person and was named by the leaders of the sub-bureau to serve as the leader of the task force. Song Bo, the captain of the criminal investigation team of the sub-bureau, is Chen Jiaxiong's old partner, and he is familiar with informality, and patted Chen Jiaxiong on the shoulder: "This case must be solved quickly, otherwise, the criminal will definitely continue to attack!" Chen Jiaxiong glanced at him: "Brother, how can you say it!"

　　The special case team held its first case analysis meeting in the conference room of the Huajiang Road police station, where the white powder on the walls was peeling. Lu Guangming said: "The criminal can climb from the water pipe to the sixth floor to commit the crime, not only is he bold, but he also has the ability to underestimate it!"

　　Du Yuanguo thought that he had spent so much energy for the "internal thief" in vain, so he was angry: "This kid can use such a brain, and he is bold, maybe he has a criminal record."

！”

　　A detective named He Yalin from the criminal debt team analyzed: "The Huajiang Hotel and the Nanyang Hotel are not far away, and the criminal's staring at these two places shows that he is familiar with the terrain and public security measures in this area, and it is possible that this guy is a resident of the two police stations on Huajiang Road and Baxian Fang!"

　　This view was unanimously endorsed by the participants. Chen Jiaxiong pondered for a while and said: "The idea of 'stealing' may be moved, but his ability to climb the water and fall into the pipe is not something that he has. He must have had this kind of practice before, or he had been a firefighter, or he had worked as an outside lineman in the electricity supply bureau, or he had been a seaman, or he was a habitual thief who specialized in climbing pipes and stealing, in short, he should have shown this kind of skill. Let's take this as a clue and look it down. ”

　　Lu Guangming said, "In addition, the money and goods stolen by the criminal are also a clue, he worked hard at night and risked to get foreign currency, jewelry, watches, perfumes and so on, it will never be to satisfy his hobby of collecting, he always has to sell the stolen goods, or use them, we can pay attention to this aspect and look for clues." ”

　　According to the direction of investigation set by the case analysis meeting, the special case team conducted a four-day investigation in the areas under the jurisdiction of the two police stations, but found nothing. Stolen money and stolen goods with distinct characteristics were not found. There is only one person who is good at climbing the water pipe, that is an old man in the pipe section of the Baxianfang Police Station, who works in the power supply station, and is the leader of the outside line, he can easily climb the high telephone pole without any climbing tools, but he is a member of the Communist Party, an advanced producer, and his family background is also very good, so it is obviously impossible to be a gentleman on the beam.

　　On the evening of the fourth day, the special case group met again, re-discussed the direction of the investigation, held that there was nothing wrong, and decided that the next day all the personnel would go down to the alley to find out the clues from the masses.

　　The next day, the seven members of the task force went down to investigate for a day. In the evening, when a meeting was held at the Huajiang Road police station, Lao Lang, a detective of the criminal debt squad, provided a line of affiliation: According to a resident of Group 7 of Jianli (Shanghai's "×× Li" is the "×× Lane Residents' Committee"), Liu Xindong, the son of a neighbor he had beaten, was good at climbing, and he worked as a plasterer in the housing management office.

　　Health is under the jurisdiction of the Baxianfang Police Station, Chen Jiaxiong looked at Lu Guangming: "Old Lu, have you heard of the name Liu Xindong?"

　　Lu Guangming is the deputy director, in charge of public security, and he is very familiar with the household registration situation in the pipe section, so he thought about it for a moment and said, "There is this person, a young man, from Ningbo, but he has moved away as early as 5 years ago. Chen Jiaxiong said: "Okay, Ningbo people just like to eat salted crabs, drunken shrimp, yellow mud snails, crab paste or something, Ms. Li smelled that smell, maybe it was Liu Xindong who did it: relocation is not a reason to rule out suspicion, the entrance of the alley in the health is facing the back door of the Nanyang Hotel, and he can come to a 'old place to revisit'." Check where he moved. ”

　　The Baxianfang Police Station looked through the household registration information overnight and found that Liu Xindong's family had moved to Beixinjing Town, Shanghai County five years ago. The next day, Xiao Yang, a policeman from the Baxianfang Police Station who participated in the special investigation, and He Yalin, a detective from the criminal investigation team of the sub-bureau, went to Beixinjing together, went to the police station first, and found out the address of Liu's house. The head of the police station summoned the household registration police to accompany Yang and He, and when the household registration police heard about the investigation of Liu Xindong, he said that he was familiar with the situation of this person: After moving here in 1969, he was sentenced to three years in prison for committing a crime in January of the following year, and he has now been released from prison at the end of his sentence, and he is employed in a labor reform unit, and he does not return home for half of the week, and is said to be living in the factory.

　　When Xiao Yang and He Yalin heard this, they immediately became interested, and glanced at each other, He Yalin asked, "What crime did Liu Xindong commit and be sentenced?"

　　"Theft. ”

　　"Can you tell us more about his crimes?"

　　"I was involved in solving the case at the time, so I know about the circumstances of his crime. On the night of December 31, 1969, he climbed over the wall into the grain warehouse, climbed up to the third floor from the water pipe, smashed the glass window and entered the office, pried 14 drawers, and stole a total of 948 yuan in cash.

　　He Yalin asked the household registration police whether there had been any theft cases with similar criminal methods in the North Xinjing area since Liu Xindong's release from prison, and the household registration police said that none of them had happened, and the three of them discussed it and decided not to make direct contact for the time being.

　　The street security cadres were more energetic than full-time scouts in doing this kind of thing, and the household registration police reported the results of the investigation in less than half an hour: Liu Xindong also returned home once this week, and it is said that he lived in the factory. This has never been done before.

　　All abnormal phenomena have value worthy of investigation and study. Yang and He immediately drove their motorcycles to the labor camp. At that time, the labor reform unit was subordinate to the public security system, and the public security of the world was one, and the labor reform factory was enthusiastic to assist. The Investigation and Security Section (i.e., the security section of a general factory, but this type of section is also the public security group of the local police station, and has the right to investigate criminal cases that occur in the unit and the right to detain offenders) made a phone call to Liu Xindong's brigade (i.e., the workshop), where he said that Liu had suffered a work injury, sprained his left ankle bone, had difficulty walking, had not even worked at work, and had been living in the dormitory of the unit.

　　The scouts were dumbfounded when they heard this: Could it be that Liu Xindong is not a suspect? Slowly! When was the ankle bone injured? To what extent? Will he deliberately disguise his illness and take advantage of the opportunity to commit the crime? All these must be carefully investigated.

The detectives took a look at Liu Xindong's medical record card, which recorded that the date of Liu's injury was October 14, and he complained that it was caused by a sprain caused by a misstep while moving things downstairs, and the injury was bruised and swollen when he went for treatment. The scouts then investigated the personnel in Liu Xindong's dormitory, and all four of them testified: (1) Liu had indeed never left the factory since he was injured at work, and for the first three days, he did not even leave the dormitory, and that others had brought him three meals from the canteen; (2) when Liu usually stayed in the factory, he never went out at night except for reading books and playing cards.

　　In this way, it can be determined that the case at the Nanyang Hotel on the night of October 16 was not committed by Liu Xindong. The technical appraisal has shown that the cases of Nanyang Hotel and Huajiang Hotel were committed by the same criminal, so Liu Xindong has nothing to do with the robbery of Huajiang Hotel.

　　Five

　　The hunch of the criminal investigation captain Song Bo was accurate, on the night when the task force investigated Liu Xindong, the "Shuiluo Criminal" committed another crime!

　　Perhaps, the criminal felt that the "benefits" obtained by the previous two attempts at the hotel guests were too small and disproportionate to the risks he had, so this time he stopped patronizing the hotels and restaurants, but attacked a research institute, disemboweling two safes in the finance department, and stealing a total of 8,848 yuan and 6 jiao.

　　The stolen unit did not find out that it had been patronized by Liang Shangjun until he went to work at 8:30 a.m. the next day, and hurriedly called the Huajiang Road Police Station to report the case. Director Chen Jiaxiong was shocked when he heard the news: "Fuck! Could it really make Song Bo say that the 'water pipe' is going to act again!"

　　Chen Jiaxiong quickly led people to the scene, and after an investigation, the modus operandi was exactly the same as that of Huajiang Hotel and Nanyang Hotel, which was to climb up to the fifth floor from the water pipe and enter through the window. The only difference is that the village criminals paid attention to the "code of conduct" this time and did not leave footprints on the windowsill.

　　At this time, Song Bo led seven or eight criminal policemen to arrive, and when he entered the door, he asked, "How is it like this, it's a 'downpipe' again?"

　　Chen Jiaxiong said: "No, this kid made a big deal this time, even pried two safes, and took away nearly 9,000 yuan, and didn't even leave a corner!"

　　The amount of money stolen was equivalent to the annual wages of more than 20 workers at that time, which was a huge amount of money. Therefore, it also alarmed the Criminal Investigation Department of the Shanghai Municipal Public Security Bureau, and immediately sent police dogs to help solve the case. The two police dogs sniffed and barked at the scene for a while, but they didn't make any name for themselves, so they had to return in vain.

　　After consulting with the criminal investigation department of the city bureau, the leaders of the sub-bureau made a decision: The case was investigated in tandem with the previous two theft cases, and six detectives were transferred to expand the strength of the special investigation team.

　　As soon as the task force began its work, it came across a situation. The situation was provided by an old lady in a residential area across the road from the research institute, this old lady had a Xi - she could not sleep from 1 to 4 o'clock in the second half of the night, got up to do some miscellaneous household chores, and last night at about 2 o'clock when she was standing in front of the water bucket in the kitchen to pick up the snails, she saw a figure using both hands and feet, climbing the water pipe to climb up to the fifth floor of the research institute.

　　The old lady said, "The man climbed very fast, and when I found him, he had already climbed to the height of the window on the second floor. I've only got three or four snails, and he's already climbed to the fifth floor!

　　Du Yuanguo nodded: "Hurry, hurry! But, old man, if you call for 'catch the thief' a few times, he won't be able to get up soon, maybe he will already be sitting in the detention center after a while, at least the safe won't have to be pried!"

　　The old lady immediately retorted: "Do I dare to shout? As soon as I shouted, if he was not caught, he would definitely come to take revenge! He would climb the water and fall into the pipe, and it would not be easy to enter the second floor where I lived?"

　　Chen Jiaxiong said: "Old lady, how much time do you estimate it took him to climb from the second floor to the fifth floor?"

　　"How much time? I'll just clip a few snails, about ...... Probably less than 10 seconds!"

　　"Oh 1" Chen Jiaxiong was taken aback, "So fast? Isn't this a monkey?"

　　"He's like a period of life, thin and small!"

　　After the old lady left, everyone discussed the case. A veteran criminal policeman from the Criminal Investigation Department of the City Bureau said: "It seems that the criminal is not an ordinary 'friend' who can climb the water and fall into the pipe, he is a specially trained climbing expert!"

　　Lu Guangming said: "Yes, it seems that it is necessary for us to find out the source of this kind of extraordinarily strong climbing ability, and then investigate people according to this, so that the scope of investigation is obviously much smaller, because there are not many such people after all." ”

The task force deliberated back and forth, and felt that it seemed that this was the only way to go at the moment, so they decided to give it a try. Scouts went to the units of these three types of personnel to get to know each other, and learned that although plasterers and outside linemen can climb, their speed is very slow, and only the best of the firefighters can climb up as quickly as monkeys "whoosh, whoosh, whoosh". The task force decided to ask a firefighter to give it a try.

　　After contacting the fire department, the Shanghai Fire Brigade repeatedly selected the subordinate squadrons, and finally selected a climber surnamed Fu in the Songshan Road Squadron. Fu is 28 years old, serving as a squadron instructor and has been in the army for 10 years. He is a native of Henan, his ancestors have practiced martial arts for several generations, he began to practice martial arts with his grandfather and father at the age of 8, and he has practiced as fast as a civet cat for ten years. He was drafted into the army in 1964 as a firefighter and rose to prominence as soon as he entered training. At that time, the People's Liberation Army was Luo Ruiqing as the chief of the general staff, and the whole army was engaged in a large-scale competition, and all parties evaluated it very well. Although the fire brigade does not belong to the People's Liberation Army, it is influenced by the army and also conducts technical competitions. Fu was selected into the Shanghai team to participate in the "National Fire Games" in Beijing, and won the ranking in the climbing event. It was only fitting that the leaders of the fire brigade chose him to participate in the simulation test.

　　The simulation test was scheduled to be carried out "at the same time and in the same place", that is, at two o'clock in the second half of the night, also on the same water pipe in the research institute, and asked the old lady who provided the clue to also stand in front of the kitchen window to observe, but this time there were no snails to clip. But it doesn't matter, because the task force specially prepared a stopwatch for testing.

　　That night, the sky was clear and windless. After half past one, a jeep carrying Fu, Chen Jiaxiong, Lu Guangming, Du Yuanguo and others entered the research institute. After inspecting the scene, Fu began to make preparations such as changing clothes and tightening shoelaces. After a while, he said he could get started.

　　Chen Jiaxiong stood at the foot of the wall, looked up at the window on the fifth floor, which looked very high, and asked worriedly: "Instructor Fu, are you okay? Do you want to tie a safety rope from the window on the sixth floor?"

　　"No, I don't. The simulation is the same as the real thing, how can a thief climb the window to tie the safety rope?"

　　Bo said, walked to the foot of the wall, stretched out his hands and gently grabbed the water pipe, stepped on the wall with both feet, and moved up in the air. Lu Guangming made a gesture below, and several people from the research institute immediately spread the prepared mats and quilts on the ground in case of accidents.

　　When Fu climbed to the window position on the second floor, Du Yuanguo pressed the stopwatch. When Fu went up to the third floor, the water fell and the pipe began to shake, and he had to slow down. After a while, he climbed to the height of the fifth-floor window, stretched out his left hand to put it on the edge of the windowsill, released his right hand, quickly shook it over and grabbed the windowsill, and then climbed up to the windowsill with a pull-up.

　　Chen Jiaxiong turned his face to Du Yuanguo: "How much?"

　　"29 seconds."

　　This result should be said to be okay, but compared with what the old lady said, "only a few snails", it is obviously slow. Everyone looked across the road, and the old lady shook her hand.

　　Chen Jiaxiong was secretly taken aback in his heart, thinking that in this way, the climbing ability of this criminal would not be worse than that of Bo!

　　According to the pre-arrangement, after Fu went up, he had to go down to the ground along the same road, and he had to tie a small bag with the same volume and weight as the stolen RMB. However, Fu squatted on the windowsill on the fifth floor but did not move, shaking his head again and again. Facing the urging and inquiring eyes of the people below, he said "Look", grabbed the window frame with his hand, stretched out a leg, and gently flicked it with his toes, and the water pipe fell down with a "bang"!

　　In terms of body weight, Fu is about the same as the criminal, and he is also what the old lady called "Monkey". However, for the same water pipe (after inspection, the reason for the fall was the rusting of the hoop sleeve fixed to the wall), the criminal could go up and down freely, and the speed was fast, but Fu could not do it. What is the reason for this? The one who has the most say on this issue is naturally Fu himself, who said: "It is certain that this guy's climbing ability was not cultivated by professional skills! That is to say, he is not a firefighter, nor is he a plasterer or a lineman, but he knows martial arts and practices light martial arts!"

　　At that time, the "Cultural Revolution" had already been "reformed" to its eighth year, and the destruction of the four olds not only broke the material in the real life, but also penetrated into people's thinking, and the vast majority of people's understanding of "martial arts" had been diluted to the point of being equivalent to a few somersaults in a model play. Therefore, the scout was skeptical of Fu's conclusion, and someone asked: "Is there really a light work?"

　　Fu's answer was yes: "Yes! There are people in my hometown who practice this, and my little partner has seen them fly off the wall with my own eyes." ”

　　Chen Jiaxiong's heart sank: "Can this criminal also fly off the wall?"

　　"Not necessarily, but I estimate that it is eight or nine or ten, in short, it is a 'snitch' with strong climbing ability!"
