Ministry of Fear
by Graham Greene
In wartime England during the Blitz, Stephen Neale is released from Lembridge Asylum. While waiting for a train to London, Neale visits a village fête hosted by the Mothers of Free Nations charity. He is urged to go to the palm reader's tent to have his fortune told by Mrs. Bellane, an older woman. He asks her to ignore the past and tell the future, which startles her. She cryptically tells him to enter a contest and guess the weight of a cake as 4 pounds 15½ ounces. Neale does so and wins the cake. Then a young blond man hurries to see Mrs. Bellane. People try to persuade Neale to give the cake to the blond man, but Neale refuses.
Neale departs Lembridge with only a blind man sharing his train compartment. Neale offers him some cake. Neale sees the blind man crumbling his portion. When the train stops during an air raid, Neale's companion turns out not to be blind after all. He strikes Neale with his walking stick, steals the cake, and flees, with Neale in pursuit. The man shoots at him, but is killed by a German bomb. Neale finds the man's revolver and continues on to London.
Neale hires private detective George Rennit to help him investigate the Mothers of Free Nations. Neale meets Willi Hilfe and his sister Carla, refugees from Austria who run the charity. Willi takes him to Mrs. Bellane's London mansion (followed by Rennit). Neale is shocked to discover that this Mrs. Bellane is a beautiful young medium. She invites them to stay for her [[séance]]. Among the other attendees are artist Martha Penteel, psychiatrist Dr. Forrester, and Mr. Cost, the blond man at the fête. After the lights are dimmed, a mysterious voice claims she was poisoned by Neale, disconcerting him. Then a shot rings out – Cost is found shot dead. Neale admits to having the blind man's gun. He flees with Willi's help.
Neale goes to Rennit's office, only to find it ransacked. He talks to Carla. An air raid forces the two to shelter in an Underground station, where Neale reveals that he had planned to euthanize his terminally ill wife. He changed his mind, but she committed suicide using poison he had bought. Due to the circumstances, Neale received a light sentence of two years at the asylum.
The next morning, Carla hides Neale at a friend's bookstore. Neale spots a book by Forrester, The Psychoanalysis of Nazidom. Carla reveals that Forrester is one of her volunteers, as well as a consultant for the Ministry of Home Security. Neale is convinced that Carla's organization is a front for Nazi spies. Carla finds out that almost all the people Neale suspects are charity volunteers, all recommended by Forrester. She tells Willi about her discovery, and admits that she loves Neale.
That afternoon, Neale goes to Penteel’s flat, only to find Mrs. Bellane. The two verbally spar. He flees when Penteel returns and begins screaming for the police.
Later, Carla tells Neale what she has learned. The bookseller asks the couple to deliver some books in a suitcase since they are leaving. They are nearly killed by the bomb inside.
Neale awakens in the hospital, the prisoner of Scotland Yard Inspector Prentice. Neale persuades Prentice to search the bombed-out cottage for evidence. Neale finds a microfilm of military secrets inside a piece of cake in a bird's nest. Officials insist that the documents have only been taken out of a safe twice, the second time when Forrester's tailor, Travers, was present. Neale recalls that the empty flat was leased in Travers' name.
Prentice and Neale go to the tailor's shop, and find that Travers is Cost. Travers ostensibly calls a client about a suit - it is actually a coded message. Then, seeing he is trapped, he commits suicide. When Neale dials the number, Carla answers.
Neale slips away to confront Carla. Willi emerges, armed with a pistol, and admits he is the head of the spy ring. Another copy of the microfilm is sewn into the suit he received from Travers. Carla throws a candlestick, striking her brother's hand. The two men struggle, and Carla picks up the gun. When she refuses to hand it over to Willi, he tries to flee, but she shoots him dead. Forrester and other Nazi agents chase Neale and Carla. Prentice arrives and kills the remaining Nazis.
