The screenplay by Allan MacKinnon (from a story by crime reporter Percy Hoskins) for this post-WW2 Britflick had a lot of promise as a kind of film noir/murder mystery knockoff in a murky world of black marketeers and spivs. When a murder is committed in a Soho nightclub Maureen Maguire (Jacqueline Hill) and her boyfriend are wrongly suspected. An American detective Bob Herrick (Dermot Walsh with a variable accent) is drafted in to help Supt. Chester (Ballard Berkeley) investigate and eventually the shady club owner (John Le Mesurier) falls under suspicion but not before Maureen is endangered … The low budget production means there is no opportunity to stage anything but the most basic shot setups and practically the only redeeming element other than an uncredited track ‘On a Cloud’ (by Trevor Duncan) is the establisher of the neon-lit streets of London at night – which is used twice, at the opening and towards the conclusion. A Stanley Haynes production for ACT, made at Nettlefold Studios by director John Harlow whose exhaustion is palpable. Sigh.
