Episode 684: Foam, Steam, and Smoke (Part 1)

Scenario: Conan and Ai bump into Takagi coming out of a stakeout. He still has nightmares about falling off the plank he was tied to (see previous episode). A woman screams nearby and they discover the body of a publishing company president. 3 people were contacted by the victim right before his deadly fall. They all claim to have been alone in their apartment at the time. Takagi and Conan examine each apartment before the suspects can change anything. The first suspect shows the beer he recently poured out still foaming at the top. The second suspect shows her cup of hot coffee still steaming on the table. The third suspect shows his cigarette still smoking after it just burnt out. All 3 also admit that they're currently in a lawsuit against the president for doctoring photos and slandering a famous actress.

All the people witnessed the publishing company president named Daisaku Katsumoto fall to his death. Conan and the police deduced the culprit must be a person inside the building, who assaulted the president and rushed to the first floor. The required amount of time should be at least 10 minutes. The three suspects all had good alibis since the cameraman named Keisuke Ogino was drinking beer with froth bubbling on the surface, the magazine editor named Kaori Tsukihara was having coffee which still had steams, and the writer named Kazutomo Sodesaki was smoking a cigarette with smoke still coming out. Takagi performed repeated experiments to show that the threshold limit for froth, steam or smoke to stop coming out was 7 to 8 minutes. Or was there something else going on?

Through investigation, all of them confessed they held grudges with the murdered. Katsumoto had used their names to publish a fake article claiming that a popular actress was having an affair while engaged with a man. The "man in the affair" was actually her half-brother which the actress had to keep secret, because he was born from an affair her father had. Pressure and the cancellation of the marriage drove her to commit suicide. The half-brother was attacked by her fans and is still in a coma. They had prepared to take legal action against Katsumoto for the article.
