There’s never a bad time of year to dive into a great mystery thriller book, but something about fall and winter—with their longer nights and sweater weather—makes them the perfect time to hunker down with a heart-racing whodunit. The best books of the genre perfectly combine a mystery and eerie tone with a puzzle so cleverly constructed that it’s almost impossible to solve before the narrator spells it all out, plus enough shocking twists and suspense to keep you on the edge of your seat the entire time.

Luckily for fans of thriller books, there’s no shortage of installments in the genre, which stretches back hundreds of years to include classics from the likes of Edgar Allan Poe and Arthur Conan Doyle and spans tales of detectives, spies, and everyday citizens out for revenge. Here, we’ve rounded up dozens of the best mystery thriller books, from those iconic early entries to mid-century bestsellers from Agatha Christie to modern classics from Gillian Flynn, Liane Moriarty, and S.A. Cosby to even newer novels. Consider your reading list sorted for the foreseeable future, and good luck solving! Below, find the 36 best mystery thriller books of all time.
