Richard Todd (wearing a vat of Brylcreem on his hair) agonises over whether he should run away with his peroxided mistress (Christine Nordern) or return to to his stolid missus (Valerie Hobson). He jumps out of a train, and thinks he's caused multiple deaths. Lots of angst ensues, especially when it looks like the loyal missus won't believe in his innocence. As a melodrama it's not too bad, despite the cheat in the plot, and Todd's hammy performance. For once, horsey Ms Hobson's frigidity is welcome. As the loyal old stick, she refrains from chewing the scenery. Her hair, however looks as ugly as her clothes. Ms Nordern also acquits herself well. She's hefty, predatory and suitably tarty (she also sports an appalling hairdo)..but she seems genuine...there's a scene in which she kisses Todd with what looks like genuine sexual hunger - something you don't often see in twee British thrillers like this. The best thing in the film is probably the arty camera-work.. there are some really interesting angles. There's a sequence in an old hotel where the camera and direction becomes almost Bergmanesque. Todd and Vida Hope (the hotelier) all moodily lit, suddenly launch into some very slow dialogue as though there's some deep meaning to their standard mystery story exchange. Early on Dora Bryan (always a joy) appears briefly as a waitress, who serves Todd and Nordern with some rock cakes - which are integral to the plot. Non-British viewers may be baffled by these delicacies; but I urge them to inquire no further.
