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 question as to why Otaki-san came 
to Gaiheikan two nights ago...
متعلِّق بسببِ مجيء أوتاكي-سان
...إلى غايهيكان قبلَ ليلتين
Es stellt sich ja die Frage, warum sie
zwei Nächte vorher zum Gaiheikan kam.
Hace dos noches,
Hace dos noches,
J’ai découvert pourquoi Otaki
était venue à la pension avant-hier soir
Il motivo per cui, l'altro ieri sera,
Sobre o motivo que fez a O-Taki
vir ao Gaiheikan duas noites atrás...
Вопрос в том, для чего О-Таки 
приходила в Гайхэйкан две ночи назад...
