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.
I've gone there with my family
several times to escape the summer heat.
لقد ذهبت إلى هناك مع عائلتي عدة مرات 
 .للهروب من حرارة الصيف
Dort hat meine Familie oft Flucht
vor dem Sommer gesucht.
Iba con mi familia para escapar
del calor del verano.
On y allait en famille
pour fuir la chaleur.
Ci sono stato spesso con la mia famiglia
per sfuggire all'afa estiva.
Fui lá muitas vezes com minha família
para escapar do calor do verão.
