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...
Let's say that Professor Kindaichi 
left the room long before the murder.
لنفترِض أنَّ كيندايتشي-سينسي غادرَ
الغرفةَ قبل وقوعِ جريمة القتل
Sagen wir, Herr Kindaichi verließ den Raum,
noch bevor der Mord geschah.
Presupongamos que Kindaichi dejó
la habitación antes del asesinato
Presupongamos que Kindaichi dejó
la habitación antes del asesinato
M. Kindaichi déclare être parti
bien avant le crime,
Il professor Kindaichi
Digamos que o Professor Kindaichi deixou
o quarto muito antes do assassinato.
Допустим, учитель Киндайти 
покинул комнату задолго до убийства.
