Kyousuke has been arrested. Hagiwara Sakutarou, Nomura Kodou, and the others gather at the "milk hall," a small cafe serving European beverages and foods, to try to discover the truth of the situation. Each of the literary men unveil their deductions. Natsume Souseki introduces Akutagawa Ryuunosuke who also participates in the puzzle solving, but none of them come up with a deciding theory. As they ponder, a boy named Hirai Tarou steps forward. Hirai tells them that everything started two nights ago...
The reason neither of them can be the killer 
is the way they light their cigarettes.
سبب استِحالة أن يكون أحدهما القاتل
هو أسلوبهما في إشعالِ السّجائر
Sí. Es imposible que sean ellos
por su forma de encender el cigarrillo.
Sí. Es imposible que sean ellos

Je sais qu’ils ne sont pas coupables
Sei que nenhum deles é o assassino pela
forma como eles acendem o cigarro.
Я понял, что никто из них не убивал О-Таки
по тому, как они зажигали спички.
