22. Strange bells

In the middle of the night, suddenly, a dark shadow sneaked up in front of a small shop in the mountain village. Shadow pulled out his sharp knife and gently opened the latch.

Uncle Li heard movement outside in the haze and was busy getting up in the dark. At this moment, he was hit hard with two sticks on his head, and he fell to the ground with a "thud" sound.

The gangsters ransacked the shop and fled. Just as the gangsters fled the scene, Uncle Li woke up. He wanted to get up, but his body had been tied to a wooden chair by the gangsters; He wanted to shout, but a towel was stuffed in his mouth. He regretted that he was not vigilant enough to go to bed when he hit more. But it was too late, and he passed out again with pain.

In the early morning, someone passed by here, saw the store door wide open, the small shop was stolen, and hurriedly reported to the township police station. Elder Hong and police officer Xiao Xu quickly arrived at the scene of the crime. Uncle Li's injury was not too serious, and his consciousness was much clearer at this time. Lao Hong said to Xiao Xu, "I will go to investigate the scene, and you will first ask Uncle Li about the crime here."

Lao Hong came to the business room and examined it carefully. But the criminals who found nothing were too cunning, not a single fingerprint was left, and the footprints were not cleared with something.

Xiao Xu was talking to Uncle Li in the room. "When did the crime happen?" I don't know. ”

"When did you wake up?" I don't know. ”

"What do criminals look like?" I don't know. ”

Xiao Xu saw that Uncle Li didn't know when he asked three questions, and asked impatiently, "Then what do you know?"

Uncle Li blushed and bowed his head in embarrassment, "Dangdang..." A bell rang on the wall.

Hearing the bell, Uncle Li suddenly remembered something and exclaimed, "Yes, I know when the boy escaped." He narrowed his eyes and recalled, "When the boy left, he was probably afraid that I would report the crime and tie me to a chair." He tossed me up like that. I couldn't see anything, but I heard the bells ringing. ”

"How many times?" 4 sounds. ”

"Great! This shows that the criminals fled the scene at four o'clock. "Xiao Xu was just about to go out and call out to Lao Hong, but he was stopped by Uncle Li again." No, not four o'clock, but four bells. "Four bells, isn't it four o'clock?"

"It wasn't continuous, it was all heard every once in a while." "Is the interval the same length?" yes. ”

"What time is that?" Xiao Xu suddenly came up with an idea, he took off the wall clock on the wall and did a simulation experiment. But except for four o'clock, I could no longer find four bells with the same interval. He asked Uncle Li again, "You remember correctly!" You see this clock can only hit 3 times at intervals, that is, one at 12:30, one at 1 o'clock, one at 1:30, and there can be no more than this. ”

"Yeah, what's going on?" Uncle Li also felt inexplicable, but he still insisted that he had not heard wrong.

At this time, Lao Hong came in. Listening to them talk about the 4 bells ringing, Lao Hong immediately understood and immediately said to Xiao Xu: "I know when the criminals fled the scene." Now we should immediately find out what all the suspects are doing at twelve o'clock in the middle of the night?"

Sure enough, according to this time, the queue was queued to investigate people, and the criminals were quickly caught

According to Lao Hong's deduction, the time for the criminals to escape the scene was twelve in the middle of the night

dot. So what about the 4 bells?
