Reasoning Story: The Hidden Evidence of the Little Detective

"Come to Huadu Hotel, there is a murder case here!" Early in the morning, the sheriff called for help. "I'll be there later." The little detective hung up the phone and ran with his assistant to the Huadu Hotel.

Huadu Inn is a small hotel with only four rooms. Arriving at the scene, the sheriff quickly told the little detective about the situation, and it turned out that the deceased was Kevin in room 1, and his head was killed by a blunt object at about 10 o'clock last night. But since noon yesterday, the hotel's tenants have not left the hotel. According to cameras outside the hotel, the four tenants also did not open windows. Police inspected all the rooms and did not find a murder weapon capable of being fatal.

The little detective came to the hall, met the other three tenants and the owner of the hotel, and asked, "How is Kevin the man?" He's too fierce." Kelly in room 2 said. "He has a bad temper and no qualities." Louis of Room 3 also added. "He always smokes in the living room and doesn't change as many times as he says." Bentley of Room 4 said. "He still owes me two months' rent!" The owner complained. "It seems that you all have a conflict with him." The little detective said.

Several people were silent, and the little detective looked at the leftover breakfast of several people, and his eyes suddenly lit up, and then asked, "What did you all eat for breakfast?" I drank polenta. Kelly replied. Soy milk I drank. Louis said. "I haven't eaten it yet." The owner said. "I cooked a big corn." Bentley was again the last answer.

The little detective smiled and said, "Bentley, don't act again, you're Kevin's killer." Sure enough, police detected Kevin's blood on Bentley's clothes.
