|List of novels|
Kogoro receives an invitation letter to a concert at Haido theatre from Shuuhei Oosuka, the director. Ran and Conan go along with him. Upon arriving, they meet Sonoko and Shuuhei. Shuuhei is the father of Yui Oosuka, a young talented violinist who is considered the symbol of the Shintaitou orchestra. Her fiancé, Akira Asabuki, is even more famous as he is considered a prodigy and is chosen as the conductor for the concert. While talking to Shuuhei, Conan notices a serious look on the director's face.
After the concert, the group goes to the backstage to meet Akira and Yui. However, when they go to Yui's resting room, they discover a dead man inside.
The handkerchief found in the room proves that this is a murder. Based on the schedule for the concert and the guest book that has the victim's name, he arrived at the theatre through the main entrance at 7:30 pm, and the estimated time of death is from 7:30 to 8:30 pm. Later, Conan learns from Haruna about the accident of Rieko Hori.
After investigating, Conan finds out who the murderer is. But before he can tranquilizes Kogoro to reveal the truth, Sonoko suddenly says that she knows who is the culprit. She says that one person left his seat at 7:45 pm, and that person - Shuuhei Oosuka - is the murderer. Knowing that Sonoko is wrong, Conan puts Kogoro to sleep and begins his deduction.
