In this episode, Conan and his friends come to the library to read books, but these books are boring for Conan. Because of boredom, Conan rummaged through the box and found an original book imported from abroad. The problem is that these books are put back here and wrapped.

A hand reached out from behind and took the book away. Conan looked back and saw that this man was the librarian. Friends asked Conan to look downstairs, and the police car came.

Just as several people were preparing for action, the curator came back. He opened the box Conan had looked for before, and then said to himself, that fool in Yutian wouldn't have been killed if he hadn't found this. These stupid policemen searched for a long time but didn't know Yutian was in this library. These words made Conan react.

They didn't come out until the curator went back. Then they looked at the box and all the books in it were gone. So everyone decided to look for books. After finding it, I found that all the books contained drugs, so I decided that Yutian must have been killed after discovering that the curator was selling drugs.

But behind them, the curator hiding in the dark was killed. Conan couldn't find any evidence, but because of Mrs. Yuan's inspiration, he recalled that when they took the elevator before, they were all children and shouldn't be overweight, but they were overweight.

Conan opened the elevator door, and sure enough, the body was found above the elevator door, but there was also a curator with a full face of murder. Conan finally caught the curator and handed it over to the police.
