Daisuke locks Takei up in the basement of the Kambe residence. Cho-san interrogates him to find out who the mastermind is behind all of this, but Takei is shook with fear and refuses to speak. Daisuke discovers that the reason why HEUSC is being uncooperative is related to his parents’ research. Kato goes through the documents that Cho-san gathered in his 19 years of investigating the case and finds an important photo.
And we figured out there's a Western-style
mansion on the other side of the trees.
وقد اكتشفنا وجود قصر بتصميم غربي 
 .على الجانب الآخر من الشجر
Außerdem wissen wir, dass gegenüber dem Wald
ein Anwesen im westlichen Stil ist.
Y descubrimos que hay una mansión
al otro lado de los árboles.
Derrière le bosquet,
il y a un bâtiment de style occidental.
E abbiamo capito che dall'altro lato
rispetto agli alberi c'è una villa in stile occidentale.
E descobrimos que há uma mansão de estilo
ocidental do outro lado das árvores.
