Jenny Wren (Karen Morley) gets Priam Andes (H.B. Warner) to invite three other men to his fancy coastal estate (which is very Dark House). There she reveals that she has had affairs with all four men and blackmails them all! However, soon Jenny is found dead but the culprit is a mystery. Could it be one of the four men? Could it even be Jenny's sister Esther (Anita Louise) or her fiancé?
Luckily Gary Curtis (Ricardo Cortez) is on hand to take over the investigation in lieu of the police. Who is Curtis? Well he is after some letters and has a suspect reputation but everyone seems happy to let him take over...
This film can be a bit hard going at times, the acting and dialogue at times being a bit stilted. The Dark House mystery with women's screams on cue are almost beyond parody. Of course there are some hidden passages, mysterious appearances and a big twist. There is no kitchen sink though, but everything else. Despite everything it is worth watching. Just about.
Some context may help. The film's origins was in a popular radio drama serial. This film was the only way to discover the ending of the tale!
