An Italian thriller, although made in England, with a Giallo style, but not a gory horror. Craig has had three wives die in sudden circumstances which makes the police suspicious and the insurance company wary. Soon after a courtroom clearance, he finds Baker in his swimming pool. It doesn't take much more than seeing her dripping wet in a swimming costume to get him to propose (who could blame him), so she very quickly becomes wife number four. It is only when her behaviour becomes erratic that he has cause to look into her past. He finds madness, murder and deception leading to violence and an outlandish conclusion. This is a very entertaining picture with Baker a gorgeous focus and a twisty plot.
