第 12 集: 一也調查海津博士與五藏遇害案，懷疑怪盜紳士是替罪羊。
Hajime thinks he has solved the case of the murders of Dr. Kaitsu and Gouzou. He believes that two people were involved and that they blamed the Kaitou Gentleman to deflect suspicion from themselves. He suggests that they first sent the portrait of the daughter to the exhibition to force Gouzou to admit that he had a daughter, which ushered Sakura into the mansion. However the painting had the Southern Cross in the night sky which meant that, it was not painted by Gouzou, but a ghost painter he employed in Okinawa. Dr. Kaitsu was his accomplice, but they crippled the painter with drugs and sent him to a hospital in Okinawa where he has since died. Hajime accuses Sakura of the murders, unknowingly assisted by the butler Komiyama. She admits that she did it because her father, Nobuhiko Izumi, was the ghost painter, however she takes her own life and confesses her feelings for Hajime before she can be arrested.
