A rare, late excursion into noir for Ealing Studios, scripted by first-time director Holt and critic Ken Tynan and intended as 'the least Ealing film ever made'. A good-looking ex-con (George Nader) coolly robs an old lady of her coin collection, anticipating prison, but also the later recovery of the proceeeds. Nothing proves that simple and he discovers the truth of the film's title. Stylish low-key cinematography, a jazz score and Maggie Smith's debut performance add to the pleasure.
