Chapter 146 The Bitten Apple
Detective William received a report from the director of a scientific research institute, saying that he had just received a threatening phone call asking him to hand over a top-secret document, otherwise he would die.He had no choice but to ask the inspector to come to his house at 7:[-] p.m. to talk about the situation in detail.

At 7 o'clock in the evening, the inspector arrived at the director's house on time and rang the doorbell, but there was no answer.Seeing that the light was on in the room, he accidentally turned the doorknob, only to find that the door was open.The detective rushed into the room and saw the director fainted under the sofa, with a handkerchief reeking of narcotics thrown beside him.

At this time, the director slowly opened his hazy eyes, instinctively touched his pocket, and cried out: "It's over, someone took away that top-secret document."

Upon hearing this, the inspector hurriedly asked, "Who is it? When?"

The director looked at his watch and said, "About 30 minutes ago, I was eating an apple while watching TV. I heard the doorbell rang. I thought it was you. Unexpectedly, when I opened the door, I was pushed back by two men with guns." , asked me for this confidential document, I pretended not to know, they immediately covered my mouth and nose with a handkerchief, and I will know nothing from now on.”

Sure enough, the half-bitten apple by the director was rolling under the TV, and the power of the TV was cut off.The inspector picked up the apple from under the TV, glanced at it, and said, "Boss, you must have sold it to them yourself!"

When the director heard this, he was taken aback and said, "Me? How can this be reasonable!"

"Stop acting, the criminal is yourself!" The inspector glanced at the director and threw the apple in front of him.When the director saw it, his face turned pale, and he helplessly handed over the large bag of dollars hidden in the refrigerator.

Excuse me, do you know how the inspector saw through the director's lie?

[Answer] The detective relies on the apple to see through the director's lies.

It turns out that there is a kind of oxidized alcohol in the cells of the apple epidermis.Usually, it is tightly wrapped by the cell membrane and does not come into contact with the air. Once the cell membrane is broken, the oxidized alcohols will oxidize with the oxygen in the air, resulting in the discoloration of the apple.

The apple bitten by the director has not changed color.If it was true that the director said he was anesthetized and passed out 30 minutes ago, then the color of the apple should have changed.
