Charitos interrogates Niki Kousta. After the discovery of the photograph, Niki is forced to admit her relationship with Petrouia. Niki describes to Charitos how Petrouia was kidnapped by three unknown men on the island where they had gone on vacation. When she went to ask her father for the rest of the money, she realized that he was responsible for her boyfriend's disappearance. Charitos knows that now only the last piece of the puzzle remains. And that is none other than the white-haired man. He decides to look for two people he believes may have crossed paths with him on the night of Kousta's murder. And he is triumphantly vindicated... He learns that along with the white-haired man, there was a brunette woman with short hair. He immediately goes to Niki Kousta's apartment, where Elena is also present. Charitos explains his theory to Niki: that she blackmailed her father over the murder of Petrouia and that she killed him.
