The Detective's Code

The blurb has been deleted because of a disgraced character. One day, A letter suddenly appeared on Ranpo's desk / Sherlock's workbench. They found it rather interesting. The letter read: "To the great detectives: Hello, Edogawa Ranpo / Sherlock Holmes. I am a client who wishes to hire the three most famous detectives in the world to help me. As a reward, the one among you with the highest score will receive one wish. The wish cannot be the destruction of the world or anything that would alter the course of the world. Sincerely, a client who means it. Please choose whether to accept the case." The two of them looked at the letter and said, "This is quite interesting, but who are the others?" The author's writing is poor and the characters aren't very smart. Any OOC is my responsibility. Ensemble cast, no romance. Theme: Let's go, you two geniuses!
