8 Locked Room Mysteries To Keep You Guessing

8 Locked Room Mysteries To Keep You Guessing

Puzzles and escape room challenges are more popular now than ever before. If you enjoy figuring out how to escape the seemingly inescapable, consider reading a locked room mystery. This subgenre of mysteries is also called impossible mysteries because while a murder’s been committed it appears that the potential suspects all have airtight alibis.

Think about the movie Knives Out – the sleuth has to puzzle out who committed the crime and how they managed it. Locked room mysteries or impossible mysteries take place in a locked room or an isolated area like a remote island with a very limited number of suspects. The suspects always have alibis. And sometimes, they become the next victims.

Nine people gather at a remote health resort. Some are here to lose weight, some are here to get a reboot on life, and some are here for reasons they can’t even admit to themselves.

But none of them could imagine just how challenging the next ten days are going to be.

Frances Welty, the formerly best-selling romantic novelist, arrives at Tranquillum House nursing a bad back, a broken heart, and an exquisitely painful paper cut. She’s immediately intrigued by her fellow guests. Most of them don’t look to be in need of a health resort at all.

But the person that intrigues her most is the strange and charismatic owner/director of Tranquillum House. Could this person really have the answers Frances didn’t even know she was seeking? Should Frances put aside her doubts and immerse herself in everything Tranquillum House has to offer – or should she run while she still can?

Lo Blacklock, a journalist who writes for a travel magazine, has just been given the assignment of a lifetime: a week on a luxury cruise with only a handful of cabins. The sky is clear, the waters calm, and the veneered, select guests jovial as the exclusive cruise ship, the Aurora, begins her voyage in the picturesque North Sea.

At first, Lo’s stay is nothing but pleasant: the cabins are plush, the dinner parties are sparkling, and the guests are elegant. But as the week wears on, frigid winds whip the deck, gray skies fall, and Lo witnesses what she can only describe as a dark and terrifying nightmare: a woman being thrown overboard.

The problem? All passengers remain accounted for–and so, the ship sails on as if nothing has happened, despite Lo’s desperate attempts to convey that something (or someone) has gone terribly, terribly wrong.

If you want some science fiction with your locked room mystery, try Six Wakes. Six people wake up on a spaceship. They’re clones – usually, when you wake up, your first memory is of how your previous incarnation died. But not these clones. They all have memory gaps. And all of their previous incarnations appear to have been murdered. They’re alone in space so that means one of them did…or does it?

Told from multiple points of view with flashbacks, this one is sure to keep you guessing until the end. And also? Enjoy the cleverness of the title – six wakes meaning that each of the six crew members wakes up but also six wakes – funerals- for the six deaths.
