...featuring Deborah Kerr as the wife of American businessman Gary Cooper, both living in London. Cooper's boss was murdered and a large amount of cash stolen, but Cooper supposedly caught the culprit before he could escape. He testifies in court, and the man (Ray McAnally) is convicted. Cooper soon uses a stock windfall to go into lucrative business with Michael Wilding, and they all prosper. Several years later, Kerr discovers a blackmail letter threatening to accuse Cooper of the murder from years ago, and while he denies guilt, Kerr isn't certain, and she's always wondered where he really got that money for his business deal, as the stolen loot was never recovered.
This is mainly remembered for being Cooper's final film. He was seriously ill while filming, and he looks uncomfortable through most of it, which actually fits with the role. Kerr is the main character, though, and she does well as the increasingly worried and paranoid wife. The supporting cast is excellent, but Michael Anderson's direction lacks pace or verve. This was a flop when released, but it's not that bad, and many stars had much, much worse final films.
