The Spy in Black (US: U-Boat 29) is a 1939 British film, and the first collaboration between the British filmmakers Michael Powell and Emeric Pressburger. They were brought together by Alexander Korda to make the World War I spy thriller novel of the same title by Joseph Storer Clouston into a film. Powell and Pressburger eventually made over 20 films during the course of their partnership. The Spy in Black stars Conrad Veidt, Valerie Hobson and Sebastian Shaw, with Marius Goring and Torin Thatcher as two German submarine officers. Grant Sutherland, a minister in Powell's The Edge of the World (1937), appears in this film as a Scottish air raid warden. Plot In March 1917, Captain Hardt (Conrad Veidt), a World War I German U-boat commander, is ordered to lead a mission to attack the British Fleet at Scapa Flow, rendezvousing at the Old Man of Hoy. He sneaks ashore on the Orkney Islands to meet his contact, Fräulein Tiel (Valerie Hobson). Tiel has taken over the identity of a new local schoolteacher, Miss Anne Burnett (June Duprez), who female German agents had intercepted and chloroformed en route to the island. Hardt finds himself attracted to her, but Tiel shows no interest. The Germans are aided by a disgraced Royal Navy officer, the former Commander Ashington (Sebastian Shaw) who, according to Tiel, has agreed to aid the Germans after losing his command due to drunkenness, and Tiel implies that she has slept with Ashington to obtain his cooperation. The plan is almost disrupted when Burnett's fiancé, Rev. Harris, arrives unexpectedly, but the spies take him captive. Then the local minister, Matthews, and his wife (who had already met Harris) come to the house, but Tiel manages to get them to leave. Now equipped with the crucial information he needs about the British fleet movements, Hardt rendezvous with his submarine to arrange for a fleet of U-Boats to attack. Returning to the house, and confident that all is going to plan, Hardt makes advances to Tiel, but she rebuffs him. She leaves the house, believing she has locked Hardt in his room, but he gets out and secretly follows her, discovering that she has gone out to meet Ashington. Hardt overhears them talking and learns the truth: the British are fully aware of his presence, and have turned his mission into a trap for the U-Boats. Hardt's "contacts" are really British
