Every Time I Go on Vacation, Someone Dies

The novel is narrated by Eleanor Dash, a bestselling mystery author whose self-aware, often humorous narration frequently addresses the reader directly.

Ten years before the story begins, Eleanor traveled to Rome, where she met Connor Smith, a charming private investigator. Together they solved a series of bank robberies that ended in a murder. Eleanor wrote about these events in her debut novel, When in Rome, keeping Connor's real name. Before publication, Connor discovered the manuscript and leveraged a legal threat to extract a percentage of Eleanor's earnings, an arrangement that escalated into ongoing blackmail. Eleanor's publisher demanded sequel after sequel featuring Connor, trapping her in a ten-book series she never intended to write.

The story opens in Rome, where Eleanor is on a tenth-anniversary book tour. In a church confessional, she confesses her desire to kill Connor off in her next novel. Harper, Eleanor's younger sister and personal assistant, finds her and leads her out. Eleanor worries that Harper, who originally dreamed of being a writer, resents working in Eleanor's shadow and plans to quit after the trip. Their parents died when Eleanor was eighteen, leaving her to raise Harper. Connor appears and announces that someone is trying to kill him: His car brakes recently failed in the Hollywood Hills, and someone pushed him into traffic outside the Vatican the day before. Eleanor dismisses both incidents as coincidences.

The group heads to the Colosseum for a fan event. Eleanor spots Cathy, an obsessive fan she has a restraining order against. Sylvie, their tour guide, begins dispensing historical facts of dubious accuracy. Connor presses Eleanor to help him investigate the threats, revealing he is being blackmailed over a financial scheme and refuses to involve the police.

At the Roman Forum, Oliver Forrest, Eleanor's ex-boyfriend and a fellow mystery novelist, appears unexpectedly and confronts Connor. Eleanor reflects on her two great loves: She fell for Connor at twenty-five, and Oliver put her back together at twenty-eight. She tells Oliver she plans to kill Connor off in the final book.

A scream interrupts. Harper has been mugged: Her purse, which contained credit cards, a paper itinerary with hotel details, and a master room key, has been stolen. Harper chases the thief and accidentally tackles Allison Smith, Connor's ex-wife, who is carrying a similar bag. Eleanor reviews the tour's attendee list, which includes Guy Charles (Connor's former business partner), Abishek "Shek" Botha (a mystery author on the verge of being dropped by his publisher), and Emily Ma (a young author whose debut novel closely mirrors When in Rome).

At dinner, Connor brings Isabella Joseph, a young Canadian woman he claims to have met on the plane. Eleanor nearly chokes on a fish bone, and Oliver saves her by performing the Heimlich maneuver. Connor suggests the bone was meant for him. Later, Connor overhears Eleanor discussing his fictional death with Oliver and confronts her, drawing the other guests into the hallway. He shows Eleanor a news article reporting that Davide Bianchi, the bystander who pulled him from traffic at the Vatican, was killed the following day. Connor declares that whoever is trying to kill him is someone on the tour.

Eleanor reveals the secret that has given Connor leverage over her for a decade. After the robbery case ten years ago, she pieced together that Connor had orchestrated the heists, using her as cover. Connor persuaded her not to go to the police, and when he discovered the book, he threatened to frame her as the mastermind if she ever exposed him. Eleanor recently discovered that the statute of limitations for these crimes in Italy has expired, freeing her from his hold.

The next morning, Connor fakes his own death to "smoke out" the killer. Harper discovers him motionless in bed and screams. Oliver rushes in to perform CPR before Connor sits up, alive. The stunt devastates Harper and enrages the group. On the bus to Pompeii, Harper tearfully tells Eleanor she feels her identity is entirely defined by Eleanor's career and invokes "pineapple," their childhood code word meaning the other must stop everything and put her first.

On the Fourth of July in Sorrento, someone pushes Eleanor toward a steep stone staircase during a fireworks display. Oliver grabs her dress just in time. Suspicion briefly falls on Harper after the group cites a New York Times profile in which Eleanor jokingly called Harper her "prime suspect" because of inheritance.

On a boat trip to Capri, Eleanor and Oliver construct a timeline using Shek's social media posts and discover he was near every location where an attempt on Connor's life occurred. On the return trip, Sylvie opens Prosecco for a toast. Connor declines his glass, as everyone knows he dislikes Champagne. Shek grabs Connor's untouched glass and drinks it. Moments later he collapses and dies.

Inspector Tucci, the same police inspector from the original robbery case, now demoted to Naples, takes charge. Connor accuses Allison, citing her botany background, mechanical expertise, and a lump-sum alimony payout triggered by his death. In a private interrogation, Tucci reveals that Shek was killed not by the Prosecco but by a needle device concealed on a ring found in Eleanor's backpack. Combined with the stolen master key in her purse and her notebook outlining fictional ways to kill Connor, Tucci announces he will seek an arrest warrant.

That night, Eleanor goes to Oliver's room and they reconcile. Before dawn, two gunshots are fired into Eleanor's empty bed. The gun, wrapped in Oliver's monogrammed handkerchief, belongs to Guy, who claims it was stolen while he was drugged. Suspicion falls on Harper, who possessed a master key, sleeping pills, and opportunity. Emily reveals that Harper and Connor had a secret affair, providing an additional motive.

Under pressure, Eleanor publicly confesses that Connor planned the robberies and has been blackmailing her for ten years. Oliver contacts their publisher, which sends a lawyer, Lorenzo Scaperelli. Scaperelli confirms that Tucci violated procedural rules, and no arrest warrant is issued.

On a day trip to Ravello, Eleanor realizes there is no verifiable evidence that anyone tried to kill Connor other than his own claims. She concludes he fabricated the threats and that she has been the sole target all along, though she acknowledges this theory will soon prove wrong.

At the Villa Rufolo, Eleanor climbs the Torre Maggiore tower and overhears Allison confronting Isabella. She searches on her phone for the Giuseppe family and discovers that the deceased crime boss, Antonio Giuseppe, had daughters named Isabella and Marta, and a wife whose description matches Sylvie. Three members of the family infiltrated the tour: Isabella posed as Connor's girlfriend under the surname Joseph, the English translation of Giuseppe; Marta obtained a job in Eleanor's publisher's publicity department and organized the tour; and Sophia, Antonio's widow, assumed the identity of Sylvie, the tour guide.

Sylvie appears behind Eleanor on the tower and reveals a poison-needle device on her finger, blaming Eleanor and Connor for destroying her family. Eleanor elbows Sylvie and knocks the device away. When Sylvie lunges, her momentum carries her past the top of the spiral staircase. She falls and breaks her neck. Harper arrives at the bottom, alerted by a call Eleanor initiated from her pocket.

Inspector Tucci fills in the remaining details. Isabella is arrested at the Naples train station. Captain Marco, the boat captain, is revealed as Sophia's brother. Shek had been blackmailing Connor through encrypted messages, recruited by Marta, who exploited his resentment over money lost in Connor's failed cryptocurrency scheme. The Giuseppes' plan was to kill Eleanor or Connor and frame the other. Marta arranged for Cathy to join the tour as a distraction and remains at large.

In the epilogue, set three months later, Eleanor decides not to kill Connor off. After Connor confirmed to Tucci that Eleanor had nothing to do with the robberies, she felt killing him on the page would be wrong. Her publisher agrees to let her start a new series alongside the Vacation Mysteries. Harper stays on as Eleanor's assistant. Eleanor and Oliver are together again. At a black-tie wedding on Catalina Island, Eleanor discovers a member of the wedding party dead in a supply closet with a cake-cutting knife in their back, setting up the sequel.
