The Best Mystery Books to Read in 2026

Cosy mysteries, locked rooms, Nordic noir and modern whodunnits — the best mystery books to read in 2026, sorted by mood.

Cosy

• The Thursday Murder Club — Richard Osman. Retirement village, four detectives, real warmth.
• The Appeal — Janice Hallett. Told entirely in emails. Ingenious.
• Vera Wong's Unsolicited Advice for Murderers — exactly as charming as it sounds.

Locked room and puzzle

• The Seven Deaths of Evelyn Hardcastle — a puzzle box that actually solves.
• Magpie Murders — Anthony Horowitz. A mystery inside a mystery.
• And Then There Were None — the ur-text, still unbeaten.

Modern whodunnit

• A Good Girl's Guide to Murder — YA, and better plotted than most adult crime.
• The Maid — Nita Prose. Unusual narrator, gentle heart.
• Everyone in My Family Has Killed Someone — funny and fair-play.

Bleak

• The Girl with the Dragon Tattoo — the Nordic noir gateway.
• Snowman — Jo Nesbø. Not for the faint-hearted.
• In the Woods — Tana French. Prose far above the genre average.

Series order matters here

Mystery is the genre most likely to trip you up on order — many series can be read out of sequence except for the three books where they absolutely cannot. Keeping series and instalment numbers straight saves a lot of accidental spoilers.
