We start off with a quite possibly insane man on his honeymoon, when asked by his new wife if he did indeed - as people allege - kill his first wife, she falls to her death down the cliffs! A while later wife number 3 (Hillary Brooke) contacts Dr Ordway (Warren Baxter) asking for his help to see if her husband is murderously insane or just unlucky! At a dinner party the man is later found shot dead. There are a number of suspects, including a pair of suspected vampires!
This film lures you into one story direction then abruptly changes direction, the sub-plot about whether a pair of dancers are centuries old vampires or not is another fascinating, if bizarre, swerve.
Despite the weirdness this is a solid crime B-movie, with a good locked room mystery at it's heart. The strange plot directions both make this film stand out from the usual fare though also distract from what is a pretty decent mystery.
