"Detective Conan's Library Murder" 5 1 episode in Chinese and 50 episodes in Japanese.
Synopsis: 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 all these books have been put back here and wrapped. A hand reached out behind him and took the book away. Conan looked back. This man is the curator of the library. His friend asked Conan to have a look downstairs. A police car drove up.
At this point, Conan understood, so he ran downstairs and only reached the elevator. Because his friend followed, he was overweight and had to take the stairs. Mu Mu, the police officer downstairs, has already communicated with the sheriff, saying that he is here for Yutian's staff. Tian Yu began to disappear the day before yesterday. The curator said that he worked with him the day before yesterday, and then he went back early. At this time, Conan arrived and appeared behind the police officer Mu Mu, who looked at Conan with a habitual expression. After some searching, he found no clues, so the police officer decided to search outside. Conan felt something was wrong, so he secretly stayed with his friends. 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 there were drugs hidden in the book, so I decided that Yutian must have been killed by finding the curator selling drugs.
Behind them, the curator hiding in the dark had a heart attack. Conan couldn't find any evidence, but because Yuan Tai was inspired, he recalled that when he took the elevator before, they were all children and shouldn't be overweight, but they were overweight. Conan opened the elevator door and found the body on the elevator door, but was followed by the curator with a face of lost face. Conan finally caught the curator and handed it over to the police.
