The Best Locked-Room Mysteries

Ruth Ware’s The Woman in Cabin 10 is a locked-room mystery set on the high seas. Covering an assignment for her boss, reporter Lo Blacklock joins fellow travel reporters, photographers, celebrities, and investors on the maiden voyage of the Aurora, a luxury cruise liner.

Shaken by a break-in at her apartment only days before, Lo is further startled when she wakes in the middle of the night and sees the passenger from Cabin 10 thrown overboard. The only problem: there is no one staying in Cabin 10. Lo combats paranoia, claustrophobia, and a severe case of mansplaining to uncover the truth behind the missing passenger. Ware crafts a nearly perfect locked room mystery, slowly unraveling the case until a disturbing portrait of the crime is revealed.

John Dickinson Carr, master of the locked room mystery himself, dubbed Leroux’s intriguing tale “the first locked room mystery ever written.” Narrated by the simple yet likable lawyer Sanclair, the mystery tracks the impressive beginnings of Joseph Rouletabille, a young reporter intent on discovering the truth behind an unsolvable assault.

Who could have attacked the studious Mademoiselle Stangerson, when her door was locked and windows were barred, and no one fled the room once it was finally opened? Sanclair and Rouletabille strike up a Holmes/Watson relationship as they finagle their way onto the grand estate of Glandier to track down the disappearing assailant, one you won’t see coming.

In The Speckled Band, Sherlock Holmes and Dr. Watson tackle a locked-room mystery when they are approached by Helen Stoner to investigate the mysterious death of her twin sister. Two years earlier, Julia Stoner was killed from within her locked bedroom shortly before her wedding. Her final words referenced a speckled band that had been her undoing.

When Helen is forced to stay in her sister’s room one night and hears the same noises that foreshadowed Julia’s death, she hops on the first train to London to enlist Holmes’s help. While not the most shocking of locked room mysteries, the story delivers what one would expect from a Sherlock Holmes story: clues are hidden in plain sight, our favorite crime-solving duo on a stakeout, and jungle animals roaming the English countryside.

Agatha Christie was a huge fan of the locked-room mystery, but And Then There Were None goes down as one of her finest creations. Ten strangers are summoned to a private residence on an island off the coast by a man they’ve never met. They quickly learn that he knows them, and their darkest secrets: they’ve all gotten away with murder.

But as they begin to die in a manner mirroring an old nursery rhyme, the group must band together to find the culprit, before it’s too late for all of them. Christie’s murderer is masterful and completely deranged. You’ll be guessing until the last page.
