What does Conan 322 mean? I don't understand.

The criminal who is the victim (the victim's secretary) must have informed him privately to call the police and then pretended to escape. Conan, who was kidnapped because he was mistaken for someone else, took this opportunity to escape by using the iron bars on the stairs. The deceased deliberately drove into the tunnel so that the police could not see him. Because the advertisement of bees was conspicuous, Takagi only recognized bees at first. This is also the way for the prisoner to tear off the outer package of the bee in the tunnel to make it white, and then drive it out as if nothing had happened. Do it. When driving out, Takagi couldn't see the bees outside, thought it was an ordinary car, and didn't care, but noticed that he stayed in the tunnel for a few minutes.

Also, the deceased was killed by the secretary when he arrived at his destination. Later, Conan used the voice of the deceased to draw him out. He was shocked when the secretary thought that the deceased was playing dead. He wanted to make sure and tried to kill the "dead" again. It's a pity that he didn't know he had been cheated. As soon as the name of the deceased was called out, Conan came with police officer Sato and them. The fool didn't even know he was cheated when police officer Sato subdued him. He's still saying that the victim is not dead. Cut ~ ~

Personally, I feel very complete, because I have watched this episode many times and I am very impressed.

PS: The shame of copying my answer is the rogue landlord. You saw it. I said it first.
