The Third Man

Opportunistic racketeering thrives in a damaged and impoverished Allied-occupied Vienna, which is divided into four sectors each controlled by one of the occupying forces: American, British, French, and Soviet. These powers share the duties of law enforcement in the city. American pulp Western writer Holly Martins (Joseph Cotten) comes to the city seeking his childhood friend, Harry Lime (Orson Welles), who has offered him a job. Upon arrival he discovers that Lime was killed just hours earlier by a speeding truck while crossing the street. Martins attends Lime's funeral, where he meets two British Army Police: Sergeant Paine (Bernard Lee), a fan of Martins' pulp novels; and his superior, Major Calloway (Trevor Howard), who says Lime was a criminal and suggests Martins leave town.
An official of the British occupying forces (Wilfrid Hyde-White) subsequently approaches Martins, requesting that he give a lecture and offering to pay for his lodging. Viewing this as an opportunity to clear his friend's name, Martins decides to remain in Vienna. He receives an invitation to meet from Lime's friend, "Baron" Kurtz (Ernst Deutsch), who tells Martins that he, along with another friend, Popescu (Siegfried Breuer), carried Lime to the side of the street after the accident. Before dying, according to Kurtz, Lime asked Kurtz and Popescu to take care of Martins and Anna Schmidt (Alida Valli), Lime's actress girlfriend.
Hoping to gather more information, Martins goes to see Anna at her theatre, where she suggests in passing that Harry's death may not have been accidental. She then accompanies Martins to question the porter at Lime's apartment building. The porter claims Lime was killed immediately and could not have given any instructions to his friends before dying. He also states that Kurtz and Popescu did not move the body out of the street alone, but were helped by a third man. Martins berates him for not being more forthcoming with the police about what he knows. Concerned for his family's safety, the porter indignantly tells Martins not to involve him. Shortly afterwards the police, searching Anna's flat for evidence, find and confiscate her forged passport and detain her. Anna tells Martins that she is of Czechoslovak nationality and will be deported from Austria by the Russian occupying forces if discovered.
Martins visits Lime's "medical adviser", Dr. Winkel (Erich Ponto), who says that he arrived at the accident after Lime was dead, and only two men were present. Later, the porter secretly offers Martins more information but is murdered before their arranged meeting. When Martins arrives, unaware of the murder, a young boy recognizes him as having argued with the porter earlier and points this out to the gathering bystanders, who become hostile, and then mob-like. Escaping from them, Martins returns to the hotel, and a cab whisks him away. He fears it is taking him to his death, but it delivers him to the book club. With no lecture prepared, he stumbles until Popescu, in the audience, asks him about his next book. Martins replies that it will be called The Third Man, "a murder story" inspired by facts. Popescu tells Martins that he should stick to fiction. Martins sees two thugs approaching and flees.




Wiener Riesenrad, one of many Viennese landmarks in the film
Calloway again advises Martins to leave Vienna, but Martins refuses and demands that Lime's death be investigated. Calloway reluctantly reveals that Lime had been stealing penicillin from military hospitals, and selling it on the black market diluted so much that many patients died. In postwar Vienna, antibiotics were new and scarce outside military hospitals and commanded a very high price. Calloway's evidence convinces Martins. Disillusioned, he agrees to leave Vienna.
Martins visits Anna to say good-bye and finds that she also knows of Lime's misdeeds, but that her feelings toward him are unchanged. She tells him she is to be deported. Upon leaving her flat, he notices someone watching from a dark doorway; a neighbour's lit window briefly reveals the person to be Lime, who flees, ignoring Martins's calls. Martins summons Calloway, who deduces that Lime has escaped through the sewers. The British police immediately exhume Lime's coffin and discover that the body is that of Joseph Harbin, an orderly who stole penicillin for Lime and went missing after turning informant.
The next day, Martins goes to Kurtz and demands to see Lime. Lime comes out to meet him and they ride Vienna's Ferris wheel, the Wiener Riesenrad. Lime obliquely threatens Martins's life but relents when told that the police already know his death and funeral were faked. In a monologue on the insignificance of his victims, he reveals the full extent of his amorality. He again offers a job to Martins and leaves. Calloway asks Martins to help lure Lime out to capture him, and Martins agrees, asking for Anna's safe conduct out of Vienna in exchange. However, Anna refuses to leave and remains loyal to Lime. Exasperated, Martins decides to leave but changes his mind after Calloway shows Martins the children who are victims of Lime's diluted penicillin, brain-damaged as a result of meningitis.
Lime sneaks out for his rendezvous with Martins, but Anna, still loyal to Lime, arrives and warns him off just in time. He tries again to escape through the sewers, but the police are there in force. Lime shoots and kills Paine, but Calloway shoots and wounds Lime. Badly injured, Lime drags himself up a ladder to a street grating exit but cannot lift it. Martins picks up Paine's revolver, follows Lime, reaches him, but hesitates. Lime looks at him and nods. A shot is heard. Later, Martins attends Lime's second funeral. At the risk of missing his flight out of Vienna, Martins waits in the cemetery to speak to Anna. She approaches him from a distance and walks past, ignoring him.

Question: In the movie, who does Martins summon that deduces that Lime as escaped through the sewers?
Answer: Calloway
