Ellery Queen is called in to help with a mysterious case of two men blackmailing a wealthy man, who is also searching for two lost daughters.
Ellery Queen (William Gargen) is called upon by the secretary (Edward Norris) of Alan Rogers (Ralph Morgan) to help out. Rogers is being blackmailed by two rough seamen. He has also put out a public appeal for two long-long daughters to return to him. One daughter has already turned up, but Nikki Porter (Margaret Lindsey) poses as the other one (having already met the real one!) After Rogers pays off the two blackmailers, they are found dead. Did Rogers kill them or is someone else really behind the scheme to get their hands on Roger's wealth?
A great edition in the Ellery Queen series, one where Nikki takes the lead in the investigation (for better or worse). A good plot with some enjoyable twists and red herrings.
