''Cat Among the Pigeons'' is a 1959 mystery novel by Creator/AgathaChristie, featuring detective Literature/HerculePoirot.

At the start of the summer term at Meadowbank School for Girls, a prestigious prep school in England, there is no reason for Miss Bulstrode, the popular but aging headmistress, to believe that the challenges facing her will be more than the occasional irate or inebriated parent. She scarcely listens when Mrs Upjohn, a parent, recognizes someone that she sees from her wartime days in the intelligence service. But there is a killer at the school who does not wait long to strike.

In 2008, ITV adapted the story for the eleventh season of ''{{Series/Poirot}}''. Tropes concerning the adaptation are listed on the series page.

!!This novel provides examples of the following:

* {{Blackmail}}: [[spoiler:Miss Blanche]] knew the identity of Miss Springer's killer and attempted to blackmail them. Unsurprisingly, this only gets her killed.
%%* BoardingSchool
* CoolTeacher: Honoria Bulstrode, headmistress of Meadowbanks, is not overly strict, but she seems to have an almost telepathic knowledge of everything that goes on at her school. Eileen Rich, the English teacher, also qualifies.
* DawsonCasting: In-universe. It's said of some of the older girls that they could pass for adults in their 20s. [[spoiler:In the case of "Princess Shaista", it turns out that this is because she ''is'' an adult of 25, having been switched with the real Princess.]]
* DeadPersonImpersonation: [[spoiler:Miss Blanche, who is actually impersonating her sister Angele who died, and who earned her teaching references.]] It's not as relevant to the plot as you might expect.
* HeKnowsTooMuch: [[spoiler:Miss Blanche.]]
* ImDyingPleaseTakeMyMacGuffin: ''Twice.'' Prince Ali Yusuf, who fears an assassination attempt, hands the jewels off to Bob. Bob realizes that having the jewels makes ''him'' a target, and hides them in his sister's luggage.
* MyGirlIsNotASlut: Eileen Rich, a respectable schoolteacher, [[spoiler:has an illegitimate child]] and is among the most sympathetic characters in the novel. Honoria Bulstrode, her headmistress, does not hold this against her, provided it does not become public knowledge. [[spoiler:The novel ends with the implication that Bulstrode has chosen Rich as her eventual successor.]]
* NeverOneMurder: [[spoiler:Three murders are committed by two people with entirely different motives.]]
* NotMyDriver: Princess Shaista, a student at Meadowbrook School, gets into a car to meet her uncle in London and never arrives. [[spoiler:This is a subversion, though, because it actually was her driver. "Shaista" was an impostor, and the car had come to help her disappear before she met anyone who knew the real Princess, making it look like a kidnapping.]]
* {{Qurac}}: A hunt for royal jewels from the country of Ramat.
* RedemptionEqualsDeath: [[spoiler:One of the murderers, Miss Chadwick,]] redeems herself by TakingTheBullet to stop her best friend being killed and thus atoning for her own crime.
%%* SternTeacher: Miss Bulstrode.
