Hugh Williams and Greta Gynt are super as the couple trying to prove that he didn't murder an old flame at her London lodgings. He is convicted largely due to a formidable prosecution from a suitably ebullient Francis L. Sullivan but she determines to find out what really happened. The odd thing is that there are no photographs of the victim; it's as if she had no recent past... Then serendipity takes a hand and Gynt happens upon a tune that takes her to Edinburgh and soon she is on the trail to the truth. Ronald Neame's first go from the director's chair and it's a suspenseful, taut film noir... lees die res.
