Enjoyable Thin Man style mystery film with Barnes as a reporter caught up in murder. Good supporting cast, with Sim at his most Scottish and Lexy his most irascible. First on-screen credit for Basil Dearden, who would go on to become one of Britain's best directors in the 1950s. Followed by one sequel, This Man in Paris, the next year.
Note: IMDb lists Lexy's role as Inspector Hollis, but he is referred to in dialogue as Holly throughout the film. Doyle is listed as portrayed by James Birrie, but that is a duplicate entry for James Pirrie.
