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...
What I saw in that room... 
was Otaki preparing for death.
ما رأيتُه في تلك الغرفة... كان استعداد أوتاكي للموت
Ich erblickte in diesem Raum Otaki,
die sich auf ihren Tod vorbereitete.
En aquella habitación vi a Otaki
preparada para morir,
En aquella habitación vi a Otaki
preparada para morir,
Ce que j’ai vu dans cette chambre,
c’était Otaki prête à mourir,
Ciò che ho visto in quella stanza
O que eu vi no quarto foi a O-Taki
se preparando para morrer.
В той комнате я увидел... 
как О-Таки готовится к смерти.
