Oliver Branwell (Jack Hawkins) is an insurance investigator. One of the cases he's assigned to brings Oliver a HUGE surprise...the claimant's wife is Sarah (Arlene Dahl)...a woman who disappeared out of his life some time ago. Later, Oliver has reason to suspect that Sarah and her husbands are crooks and they've sold cheap copies of paintings in their collection...keeping the originals. But before he can do anything, the evidence goes up in smoke when the manor home where Sarah and her husband had lived burns down...and Oliver nearly burns with it. While escaping from the fire, he discovers the body of Sarah's husband...and Oliver assumes he's been used. But because he is worried about exposing Sarah's possible crimes, he removes himself from the case. What's next? Well, a lot, as this only takes you to the middle of the story.
This is a VERY confusing film, so when you watch...watch carefully. Otherwise you'll find yourself going back to various portions to see them again so you can understand what has happened. The writing could have been better in this regard and the confusion is due to the writing...as the finale really didn't make a ton of sense. Otherwise, the acting is very good and the film is worth your time.
