The Woman in Cabin 10 is Ruth Ware's 2016 psychological thriller — the book that turned a cruise ship into a locked room. Travel journalist Lo Blacklock witnesses a woman thrown overboard from the cabin next to hers. Problem: officially, no one was staying in that cabin. Nobody believes her. As her investigation deepens, the question shifts from what she saw to whether she can trust herself.

On their five-year wedding anniversary, Nick Dunne's wife Amy goes missing.

by Ruth Ware
Ware's debut, and the book most readers say to try if they loved Cabin 10. A hen party in a remote glass house, old secrets resurface, someone ends up dead. Same author, same locked-location dread.
by Ruth Ware
A nanny takes a job in a smart home in the Scottish Highlands. Something happens. She writes letters from prison explaining everything. Ware's most-recommended book after Cabin 10.
by Lucy Foley
A glamorous island wedding with a killer among the guests. Dual timelines, ensemble cast, no way off the island. The Cabin 10 template in an Irish setting.
by Lucy Foley
A group of old friends, a remote Scottish estate, and a blizzard that traps them all. Same isolated-location, something-wrong-with-this-group energy.
No — it's entirely fictional. Ruth Ware has said the cruise setting came from a personal fear of cruise ships. The locked-cabin scenario is invented, though the claustrophobic atmosphere of luxury cruises is grounded in real observation.
All standalones — any order. Most readers start with In a Dark, Dark Wood (debut, fastest) or The Turn of the Key (most reviewed). Woman in Cabin 10 is the most popular entry point because of its word-of-mouth history.
Lucy Foley (The Guest List, The Hunting Party) is the most-cited contemporary equivalent. Both specialize in location-locked thrillers with ensemble casts and unreliable narrators.
