Successful psychiatrist Robert Newton (Clive) is fed up of his wife Sally Gray (Storm) and her philandering ways. He's got business to attend to and it involves her latest lover Phil Brown (Bill). Newton calmly says to Brown - "Have you ever heard of the straw that broke the camel's back? Well,......it's you" - before putting his pre-meditated plan into action. Superintendent Naunton Wayne (Finsbury) turns up about halfway through the film to try and figure things out.
The film is a battle of wits between everyone involved and it makes for entertaining viewing. The film grips you from the start and doesn't let go. Robert Newton starts off as completely likable and delivers some great dialogue in his calm and controlled manner. I totally sympathized with him but I'm not sure I was meant to. He is that appealing. I did gradually swing round to Phil Brown's side, though, after all, Newton is crackers! Great scenes, great locations, great acting and a clever dog.
There are unexpected plot twists but the ending is slightly ambiguous. I went for the interpretation that sees Sally Gray stay in character, ie, a tart.
