Literature: A Murder Is Announced
- 'In an English village, you turn over a stone and have no idea what will crawl out.'
This mystery provides examples of:
- Action Girl: In their backstories, at least. Hinch was an Air Raid Precautions warden during the war, while Emma a.k.a. Julia was in the French resistance.
- Adaptational Heroism: Patrick is generally more likeable in the Joan Hickson adaptation, shown to be worthier of Emma.
- Adaptational Name Change: Mitzi is renamed Hannah in the Joan Hickson adaptation.
- Adaptational Villainy: Edmund Swettenham in the 2005 adaptation is an altogether more bitter and unpleasant boy than in the book, and resentful of his mother's relationship.
- The Bait: Miss Marple talks Mitzi into taking this role; as a result the murderer is caught as she attempts to drown Mitzi in the sink.
- British Stuffiness: Natch.Mrs Easterbrook: Archie... there's going to be a murder.
Col Easterbrook: What time?
Mrs Easterbrook: Six thirty this evening.
Col Easterbrook: Short notice.
- Break the Cutie: The murderer's sympathetic backstory.
- Butch Lesbian: Though never explicitly stated to be one, Miss Hinchcliffe very much fits this trope.
- Dead Person Impersonation: "Letitia" is really the other sister, Charlotte. The real Letitia is long dead. Reasons had to do with inheriting a large sum of money and thinking the fraud couldn't possibly hurt anyone.
- Deadly Deferred Conversation: Miss Murgatroyd realizes "she wasn't there". Miss Hinchcliffe tells her they'll talk about it later—and Murgatroyd is murdered while Hinchcliffe is fetching a dog from the station.
- Did Not Get the Girl: Patrick. Averted in the Joan Hickson adaptation.
- The Ditz: Miss Murgatroyd and Dora Bunner. Mrs Easterbrook plays up to the trope, but is quickly revealed as a shrewd gold-digger using it as a facade.
- Does Not Like Men: Miss Hinchcliffe is convinced from the start that the murderer is a man, "because we all know what dirty pigs men are." She's wrong.
- Funny Foreigner: In what now reads as rather cringeworthy Values Dissonance, Patrick and Julia treat Mitzi, the high-strung Eastern European refugee cook, like one.
- Gold Digger: Inspector Craddock accuses Edmund of being one, but both are playing parts to try to trap the murderer. Julia accuses Patrick of being one also.
- Gossipy Hens: Letitia's neighbours react to the murder advertisement exactly as planned, by showing up at her place at the appointed time and doing a very bad job of hiding their anticipation.
- Hide Your Lesbians: There's a strong subtext between Odd Couple housemates Misses Hinchcliffe and Murgatroyd, but the exact nature of their relationship is not specified. Hinch's vengeful rage at the murderer of Murgatroyd is telling.
- His Name Is...: Poor Miss Murgatroyd. Also a case of Can Not Spit It Out, since she had plenty of time to finish the sentence.
- Kill the Ones You Love: Even though the killer loved one of the victims, she was killed out of fear that she was inadvertently revealing too much about the first murder.
- Lampshade Hanging: The 1985 BBC television adaptation introduces several examples, as follows:
- Last Minute Hookup: Philippa "Pip" and Edmund.
- Last Name Basis: "Hinch" and Murgatroyd.
- Lights Off, Somebody Dies: The one you would least expect.
- Little Old Lady Investigates: Miss Marple is of course the Trope Codifier, but she's also aware about it: "A policeman asking questions is open to the grave of suspicion, but an old lady asking questions is just an old lady asking questions."
- Luke, I Am Your Father: Julia is Philippa's sister.
- Mystery Magnet: When Miss Marple goes to Chipping Cleghorn with the excuse of visiting the vicar's wife, "Bunch" Harmon (who is a distant niece of hers), the vicar remarks, "A man dies in highly suspicious circumstances in Chipping Cleghorn, and suddenly Aunt Jane is coming to stay." Bunch isn't about to argue with him.
- Never One Murder
- Nobody Over 50 Is Gay: Miss Hinchliffe and Miss Murgatroyd, according to a discussion on the Golden Age Mysteries forum.
- Noodle Incident: The police discover something unpleasant about Mrs Easterbrook's past, but as it isn't relevant to the murder they ignore it and we never hear any more details.
- Pet's Homage Name: Rev. Julian Harmon, an Oxford alumnus, named his cat after an Assyrian king.
- Red Herring: The death of Philippa Haymes' husband in a car accident turns out to be completely incidental, and has nothing to do with the main murdet plot.
- The Reveal: A whole chain reaction of them at the Summation Gathering.
- Sarcastic Devotee: Miss Hinchcliffe is rather gruff in her dealings with Miss Murgatroyd, but shows deep affection when pressed.
- Separated at Birth: Philippa and Julia are really long-lost siblings Pip and Emma.
- Screaming Woman: Mitzi, frequently, on very little provocation. Luckily, she's also a brilliant cook.
- Summation Gathering: Subverted with Inspector Craddock's speech; later played straight by Miss Marple.
- Sympathetic Murderer: Downplayed. The murderer is shown as a weak and kindly person who was driven to kill as a result of the consequences of her unwise actions, and who was tired of living a horrible life - but, as Miss Marple points out, others had had it worse and had got back on their feet without having to resort to murder.
- Woobie, Destroyer of Worlds: Charlotte Blacklock
- Yank the Dog's Chain: Letitia's death, preventing Charlotte from enjoying the inheritance that would have, in her eyes, made up for the years of affliction she suffered.
- Younger and Hipper: Hinch and Murgatroyd in the 2005 adaptation.
