What would you do if you woke up in a strange house, not knowing how you got there, with a pistol in your hand and your cousin's body stuffed into a cupboard? If you're Griffith Jones, you talk Patricia Laffan, who knocks on your door, and your reporter friend, Bruce Seton, into helping you hunt for the killer without informing the authorities. They get wind of it soon enough anyway, when Charles Farrell, the antiques restorer and forger across the way also turns up dead.
It's a decently directed and telegraphically plotted murder mystery directed by Terrence Young. It's an efficiently produced second feature, with everyone running around London and the exurban areas, with a nice twist ending, and decent actors. Even so, it works out to be little more than a decent time-waster, although cinematographer Ernest Palmer -- the British one, just as it's the British Farrell in the cast -- gets some good night shooting at the end. It was the end of Palmer's career; he would light one more movie (the appropriately named THE CROWNING TOUCH) and retire. He died in 1964, age 63.
