In the midst of the Nazi blitz, a postman dies on the operating table at a rural English hospital. But was the death accidental? a delightful and wholly unexpected murder mystery, British writer/director Sidney Gilliat's Green for Danger features Trevor Howard and Sally Gray as suspected doctors and Alastair Sim in a marvelous turn as Scotland Yard's insouciant Inspector Cockrill. A screenwriter who had worked with Hitchcock on such classics as the Lady Vanishes and Jamaica Inn, Gilliat slyly upends whodunit conventions with wit and style.
