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.

so I think I'll be able to repay 
all the money you lent me.
لِذا أعتقد سأتمكَّن من تسديدِ

y podré devolverte
el dinero que te debo.
y podré devolverte
el dinero que te debo.

i soldi che mi hai prestato.
então acho que vou conseguir pagar
o dinheiro que você me emprestou.
думаю, смогу вернуть вам долг.
