Not much mystery here as the crime and perpetrator is known from the start so more of a how-will-they-catch-him than a who-dunnit. Still, there is charm in the setting: a dancehall where girls work to dance with patrons serves as a cover for the HQ of the local kingpin: an aristocratic yet particularly wily chap, who seems to smuggle gin and trade in 'surplus' goods, among other things. Innocents get swept up in the milieu and, though painted as too goody-goody, have a close brush with both the criminal and police world which toughens them up a bit. Barry K. Barnes plays the kingpin's chief henchman and delivers a subtle psychopathic gentleman killer vibe. There is some nice framing here and there, plus you get 1947 London, and its various pubs and characters , which helps sustain the film through its lulls (here and there), and the ending has its own minor twists. Other little highlights are scenes with Richard Attenborough and Diana Dors. I can't say it held my full attention 100% throughout but I am not regretful about having seen it - just 83 mins long! It's an alright movie if you are looking for a quite gentle noir in an unusual setting and a little but not too much excitement.
