Cat Among the Pigeons
Agatha Christie
 The story flashes back three months to Ramat, one of the richest countries of the Middle East, where a revolution is about to take place. Prince Ali Yusuf gives a fortune in jewels, which he needs sent out of the country, into the safekeeping of Bob Rawlinson, his personal pilot and the only person he can trust. Rawlinson complies with the prince's request, apparently by concealing the jewels in the luggage of his sister, Joan Sutcliffe, who is travelling with her daughter, Jennifer. He is seen doing this by a mysterious and unnamed woman in the next room. Soon after, both Rawlinson and the Prince are killed in an airplane crash while attempting to leave the country after a flight mechanic named Sergeant Achmed sabotages their plane. A number of people, including British Intelligence, get onto the trail of the jewels, and their attention focuses on Meadowbank School, where not only Jennifer, but also the prince's cousin and expected fiancée, Shaista, are studying. This term at Meadowbank there are both old and new staff. Miss Chadwick helped Miss Bulstrode found the school. Miss Vansittart has been teaching there for several years, and Miss Rich for 1 1/2 years. Miss Johnson is the girls' matron. The new staff include Angèle Blanche (a French teacher), Grace Springer (a gym teacher), Ann Shapland (Miss Bulstrode's new secretary), and Adam Goodman (a gardener, or actually an undercover British agent posing as a gardener). Miss Bulstrode is nearing retirement, and is deciding whom to appoint as her successor. The others assume Miss Vanisttart will be the successor; she would perserve Miss Bulstrode's legacy but is unimaginative and has no new ideas. But Miss Bulstrode is also considering Miss Rich, who is young and has lots of ideas but less experience. She is not considering Miss Chadwick, whom she thinks is too old (although others may assume Miss Chadwick is the second most likely candidate). But all these deliberations are cut short when Miss Springer is shot dead in the Sports Pavilion late at night, and Miss Johnson and Miss Chadwick discover her body. Following the murder, Inspector Kelsey interviews everyone and Adam Goodman reveals his true identity to Miss Bulstrode. Meanwhile, Jennifer Sutcliffe, an expert tennis player, complains that her racquet feels unbalanced (it must have been warped in the Ramat heat), and she writes to her mother asking for a new one. She swaps tennis racquets with Julia Upjohn, who prefers Jennifer's racquet because it has been refurbished recently. Later a strange woman arrives and gives Jennifer a new racquet, saying it's a gift from her aunt Gina. The woman takes the old racquet (actually Julia's), ostensibly to return it to Aunt Gina for restringing. Later, Julia points out that this is impossible because Aunt Gina knows that Jennifer's racquet had been refurbished and restrung recently, so she would not assume the problem is in the strings. Sure enough, Aunt Gina writes to say that she has not sent a new racquet. During a weekend when many of the girls are at home with their parents, Shaista is apparently kidnapped by a chauffeur posing as the one sent by her uncle to take her home. That night there is a repetition of murder when Miss Chadwick is disturbed by torch light in the Sports Pavilion and Miss Vansittart is found dead there, having been apparently coshed. Many of the girls go home, but the resourceful Julia, who has been pondering the exchange of the racquets, takes her (really Jennifer's) racquet back to her room and discovers the gems in the hollowed-out handle. She hears someone at the door who quietly turns the knob and attempts to enter. But Julia has pushed furniture against the door to prevent a murderer from entering. The next day Julia flees the school to tell her story to Hercule Poirot, whom she has heard of through a friend of her mother. The police start to focus on the newcomer, Miss Blanche, but in fact she is not the murderer. Instead, she knows who the murderer is, and makes an attempt at blackmail that backfires when she is also killed. With the school struggling to survive the scandal of two murders, the denouement has arrived. Poirot reviews what the reader already knows, and then explains that Princess Shaista was an impostor: the real Shaista had been kidnapped earlier in Switzerland, and the apparent abduction was actually the imposter's escape from the school. She was the representative of one group of interests who, crucially, did not know where the gems had been concealed. The murderer, however, did know where the jewels were concealed and must have been in Ramat to see Bob Rawlinson hide them. Most of the teachers could not have been there … the exception was Eileen Rich, who was apparently sick at the time but was in fact in Ramat. Jennifer had even recognised her, although she remembered the woman she had seen as a fatter woman. (It later transpires that Miss Rich had been in Ramat for the delivery of an illegitimate child that was stillborn.) Just as it seems that Miss Rich is the murderer, Mrs. Upjohn enters the room having been recalled from her holiday in Anatolia and identifies by face the woman she had seen through Mrs Bulstrode's window: Ann Shapland, who is well known in intelligence circles as a ruthless espionage agent and a mercenary. It was Shapland who had had the room next to Bob Rawlinson at the start of the book. Ann Shapland draws a pistol and Miss Bulstrode steps in front of Mrs. Sutcliffe; Miss Chadwick does the same to protect Miss Bulstrode, and is fatally wounded. It is revealed that Ann Shapland murdered Miss Springer, who caught her while she was searching the Sports Pavilion for the jewels. She also murdered Miss Blanche, who knew her secret and tried to blackmail her. But she did not kill Miss Vansittart, and had a perfect alibi for that night. Miss Vansittart was actually killed by Miss Chadwick, in an unpremedited fit of passion. Miss Chadwick had found Miss Vansittart in the Sports Pavilion the second night, kneeling in front of Shaista's locker, apparently snooping. Miss Chadwick disliked Miss Vansittart and did not consider her a suitable successor for Meadowbank. Miss Chadwick was carrying a sandbag for protection, and here was Miss Vansittart in a perfect position to be coshed from behind. Barely conscious of her actions, she kills her. But she feels immediate remorse, and later throws herself in front of a bullet to save Miss Bulstrode. As Miss Chadwick lies dying, she confesses that she imagined the removal of the widely presumed successor would make Miss Bulstrode change her mind about retiring. So the first and third murders are linked by the same murderer, while the second and third murders are linked by the same method (a sandbag). Shapland used the sandbag to make it seem that the second and third murders were linked, since she had an alibi for the second murder. At the end of the book, Miss Bulstrode reconfirms her decision to make Miss Rich her eventual successor. Poirot turns over the gems to the enigmatic “Mr. Robinson” who, in turn, delivers them to the English woman who has been secretly married to Prince Ali Yusuf. One emerald is returned as a reward to Julia Upjohn.
