At Bertram's Hotel is a 1965 novel by Agatha Christie, featuring Miss Marple.
Miss Marple is holidaying at the titular hotel, where she meets her old friend Lady Selina Hazy, and encounters a variety of other guests including the adventuress Bess Sedgwick, the young heiress Elvira Blake, her guardian Colonel Lunscombe, and the forgetful Canon Pennyfather. The latter is supposed to fly to Switzerland for a conference but misses his flight by a day, returns to the hotel, and is knocked unconscious, before waking up four days later outside of London near to a recent train robbery where witnesses say they saw him; Miss Marple also saw him leaving his room fully conscious several hours after he was knocked out. Meanwhile, Elvira's money is being held in trust until she comes of age, and she asks her guardians who would inherit if she died, and hints that she is planning to get married. When a murder takes place, Police Chief Inspector Fred "Father" Davy, already involved in the mystery, teams up with Miss Marple to uncover the various crimes…
The novel has been adapted twice for television: firstly in 1987 as part of the BBC Miss Marple series starring Joan Hickson, and secondly as a 2007 episode of ITV's Marple. The latter made many large changes to the plot.
The story contains examples of the following tropes:
- Action Girl: Lady Sedgwick is an adventuress—she flew solo across the Atlantic, she fought with La Résistance in France—and her action skills shine in the climax of the novel.
- After-Action Villain Analysis: Subverted. After Bess Sedgwick crashes and dies, her confession and motivations are discussed, when Miss Marple quietly reveals that she falsely confessed to protect her daughter Elvira, the real murderer.
- All Girls Want Bad Boys: As usual for a Christie novel, it ends badly for everyone. Elvira loves Stanislaus, who loves... her money (and was her mother's intermittent lover). Recognizing that she wouldn't get Stanislaus without the money, and thinking she might be illegitimate, she carries out a completely unecessary murder.
- All for Nothing: It turns out that Elvira's fears about her mother's marriage to Gorman depriving her of her inheritance by making her "illegitimate" were unfounded, and thus, unknown to her, there was nothing for her to gain from killing him.
- Back-Alley Doctor: Dr. Stokes, who tends to Canon Pennyfather, has had his license revoked because he was "helping a lot of girls who were no better than they should be"—in other words, being a back alley abortionist. He's still a back-alley doctor in the present day, working with the crime ring that runs out of Bertram's.
- Badass Driver: Lady Sedgwick turns out to be one. She commits suicide by crashing her car after driving very fast and recklessly, but Father notes that her driving was actually magnificent, and that against the odds she avoided any other casualties or property damage.
- Bad Habits: Canon Pennyfather is incapacitated and impersonated as part of a robbery, for which he is to be the scapegoat.
- Breach of Promise of Marriage: A little comic scene has Richard Edgerton, Elvira's lawyer, telling a client he's going to have to shell out at least £12000 to settle a breach of promise suit.
- Brits Love Tea: Part of the sort of staged English role-playing at Bertram's. Afternoon tea is staged for the benefit of American tourists, who want to see the Brits enjoying their tea.Tea as a meal had rather gone out of fashion since the war. But evidently not at Bertram's.
- Busman's Holiday: Jane Marple is roped into solving a murder while holidaying at the titular hotel.
- Climbing Climax: Near the end of the story, Lady Sedgwick confesses to the murder and then flees by climbing the drainpipe to the roof of the building, managing to elude all of Father's men, before scaling down the far side, driving away recklessly in her car and crashing fatally. She did this deliberately, and the confession was a false one to protect her daughter.
- Continuity Nod:
- Miss Marple's nephew Raymond West and his wife Joan talk about how Miss Marple got mixed up with a murder the last time they sent her on vacation, to the West Indies; that is the plot of A Caribbean Mystery.
- One of several links between the Hercule Poirot and Marple universes is the appearance of Mr. Robinson, a shadowy spymaster type who first appeared in Poirot novel Cat Among the Pigeons.
- Comic-Book Time: After having been originally presented as a subversion of the "Victorian Aunt" stereotype in her initial appearences, Miss Marple is described as having had a "Victorian Aunt" of her own in this novel of 1965.
- "Could Have Avoided This!" Plot: If Elvira Blake had just talked to a probate lawyer about her father's will, she would have found out the murder was completely unnecessary.
- Demoted to Extra: Miss Marple! She has little to do with the solution as Chief Inspector Davy figures everything out by himself. In their conversation at the end Miss Marple naturally reveals that she has also figured out who the killer is, but if the character of Jane Marple were deleted from this book the story would hardly be changed.
- Face of an Angel, Mind of a Demon: Miss Marple references this trope in regard to the murderer:"The children of Lucifer are often beautiful - and, as we know, they flourish like the green bay tree."
- False Confession: Bess Sedgwick makes one in order to protect the real killer, who is her daughter.
- Heroic Sacrifice: Bess Sedgwick pulls one in order to cover for Elvira.
- Instantly Proven Wrong: Chief Inspector Davy reassures an anxious Miss Marple, telling her that while there's definitely something fishy about Bertram's Hotel, "There won't be any murders." In the very next sentence a "sharp report" is heard from the street—someone has been shot to death outside.
- Left Hanging: The book ends with Chief Inspector Davy, who has identified Elvira as the killer but admitted that he has no evidence, vowing that he won't let her get away with it.
- Love Makes You Evil: Elvira Blake was desperately in love with Malinowski, but knew that he would only marry her for her money. She killed Gorman out of fear that because his marriage to her mother made her father's marriage bigamous, Elvira might have, due to being "illegitimate", lost her inheritance, and thus also lost Malinowski. As it turned out, this fear was baseless.
- Murder by Mistake: Micky Gorman is accidentally shot while defending the intended victim from an unknown assailant. Or so it seems; the so-called "intended victim", Elvira, was the actual assailant who deliberately killed Gorman.
- Nostalgia Filter: Betram's Hotel deliberately plays up to this, going to great effort to appear to the guests as if the early Edwardian era never ended.
- Old Flame Fizzle: In the backstory, and a rare glimpse into Miss Marple's personal life. Miss Marple, reflecting on Elvira and Elvira's sleazy boyfriend. She remembers that she himself had a "friendship" with a man in her youth. But her mother put a stop to it, which Miss Marple was grateful for years later when she met the man again and he was "quite dreadful."
- Oops! I Forgot I Was Married: Lady Sedgwick and Micky Gorman had married in Ireland, and he had told her that it was just a game and not a legal union, but in fact the marriage was genuine, making all four of her subsequent marriages unwittingly bigamous.
- Scatterbrained Senior: The elderly and forgetful cleric Canon Pennyfather, who arrives one day late to the airport for his flight.
- Separated by a Common Language: Lady Selina complains that when she was in America, she ordered a muffin and it was a sort of teacake with raisins. "I mean, why call them muffins?"
- Sibling Triangle: Actually a parent-child triangle, as both Lady Sedgwick and her daughter Elvira have been lovers of racing-car driver Ladislaus Malinowski.
- Swiss Bank Account: The Hoffman brothers, the actual owners of Bertram's Hotel, hide their money in Swiss bank accounts.
- Thrill Seeker: How Bess Sedgwick the Action Girl characterizes herself. She says all her "running into danger" is "More an addiction. Like a drug." She fights with the French Resistance and stows away on nuclear submarines for the thrills.
- Train Job: An entire scene has a gang of criminals hijack and rob a train.
- Unbuilt Trope: Adaptations of Agatha Christie works since the 1970s have sometimes been criticised for romanticising and idealising the Genteel Interbellum Setting. One of the last Miss Marple novels, At Bertram's Hotel, written and set in the 1960s, depicts the "timeless" and old-world atmosphere of the titular London hotel as a front for a criminal conspiracy, and ends with Miss Marple deciding that one must accept that the world has changed and not try to live in the past.
- Uncanny Valley: The titular hotel is this, full of the retired military officers and Grande Dames one would expect in a hotel that seems frozen in the past. It doesn't take Miss Marple long to realize that something's off about the place. She's not wrong; the place has been set up this way deliberately to serve as a front for a crime ring.
- The Unfettered: Lady Sedgwick, the adventuress. Discussed by Police Chief Inspector "Father" Davy.Father: "She's a woman in a thousand, you know. One of the wild ones. Oh, we've some of them in every generation. You can't tame them, you can't bring them into the community and make them live in law and order. They go their own way... They'd have been all right, I suppose, born in another age when it was everyone's hand for himself, everyone fighting to keep life in their veins. Hazards at every turn, danger all round them, and they themselves perforce dangerous to others. That world would have suited them; they'd have been at home in it. This one doesn't."
- Vacation Episode: For the second book in a row (after A Caribbean Mystery), Miss Marple takes a vacation and winds up getting mixed up in murder and crime.
