    NOTES: Film debut of George Cole.

    COMMENT: Well above average spy melodrama with a really stunning climax. Very slow to get moving but the plot, once it starts, really engages the attention.

    Asquith's direction is never less than highly competent, and he has drawn some splendid performances from a remarkably skillful group of actors who keep us guessing right up to the climax as to the actual identity of the spy.

    And even when the player concerned finally shows his colors, we still expect to find that he is actually a counterspy.

    Yes, the final action sequences are well worth waiting for. They're staged with an absolutely brilliant finesse that was so much admired by Orson Welles that he copied the idea in "The Lady from Shanghai" (1948).

    Did Orson's super-charged version do it better? I don't think so. And in the Welles film, it's one of the support players (Glenn Anders) who walks away with the acting honors. In this film, it's hard to choose between John Mills, Alastair Sim, George Cole and Michael Wilding. All of them show sufficient quirks to qualify.

    Appealing support is provided by Jeanne de Casalis as a typical aristocratic eccentric, the lovely Carla Lehmann as the love interest, Frank Cellier as the cabinet minister, and Wally Patch as the obliging Evans.
