Fukuzawa meets the young intelligent detective Ranpo Edogawa who has surprised him with his highly developed intelligence when solving cases and agrees to help him find a job. As Ranpo deduces from Fukuzawa's appearance that he is a former war soldier who killed several people in a previous conflict, Fukuzawa is stressed by remembering his past but still decides to help Ranpo with a job.

In the play, the leading actor appearently dies and Ranpo asks Fukuzawa to calm the viewers.

| Apparently en route to the police station, Mitamura praises Ranpo's deduction skills and Fukuzawa's prowess in solving the recent case. However, Ranpo claims that Mitamura still doubts him possessing an ability, so he offers to answer the cop's questions until he runs out of queries to prove that he is truly gifted. As a start, Ranpo correctly deduces that they are not heading to the police station, which Mitamura dismisses can be easily observed. Ranpo then urges him to ask anything related to the recent incident, to which Mitamura asks how the suited man restrained in the theater was captured. The detective reveals that someone abducted the man using a rug and organic solvent, whom Mitamura guesses must be the playwright Kurahashi, but Ranpo states that the latter must have been already killed even before the performance. He also points out that the entire project is an elaborate ploy all to abduct the suited man, afterwards slyly calling out Mitamura for reeking of organic solvent. ||||||
