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...
Everything started during
 the events of two nights ago.
بدأ كلّ شيء أثناء الأحداث الواقِعة
قبل ليلتَين
Es begann alles in der Nacht
von vor zwei Tagen.
Todo empezó hace dos noches.
Todo empezó hace dos noches.
Tout a commencé
la nuit d’avant-hier.
La cosa
Tudo começou duas noites atrás.
Всё началось две ночи назад.
