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 that covering up for the terrorism
at the embassy was your doing...
وأنك وراء التستر على الإرهاب 
 .الذي حدث في السفارة
Und auch bei der Vertuschung
des Terroranschlags in der Botschaft
Y que encubrir el terrorismo
en la embajada fue cosa tuya…
L’affaire de l’ambassade
qui a été étouffée,
E che l'insabbiamento dell'atto terroristico
avvenuto all'ambasciata sia opera tua.
e que encobrir o terrorismo
na embaixada fosse obra sua.
