A great thriller does something no other kind of book can: it makes you resent sleep. You promise yourself one more chapter, then it is somehow two in the morning and you have stopped pretending you will stop. The very best of the genre hook you on the first page and refuse to let go until the last. Here are twelve mysteries and thrillers worth losing a weekend to, mixing timeless classics you can read for free with modern page-turners that started their own crazes.
There is something here for every mood, from tidy golden-age puzzles to twisty psychological thrillers, so pick the one that matches yours and clear your evening.
Timeless classics you can read free
The Adventures of Sherlock Holmes by Arthur Conan Doyle is where detective fiction was truly perfected, and because it is in the public domain, it is free to download. The short-story format makes it ideal for dipping in, and Holmes and Watson remain the template every detective duo since has copied. For Holmes at full novel length, The Hound of the Baskervilles adds a brooding moor and a legendary spectral beast, and it too is free.
The Woman in White by Wilkie Collins is an early, atmospheric mystery that still genuinely grips, full of secrets, disguises, and dread, and available free as a classic. If you think old mysteries must be dry, this one will change your mind fast.
Golden-age puzzles
And Then There Were None by Agatha Christie is, for many readers, the finest puzzle mystery ever written: ten strangers lured to an island, picked off one by one, with a solution that has never been bettered. The Murder of Roger Ackroyd, also by Christie, is famous for a twist so audacious it changed what mystery writers thought they were allowed to do. Christie earned the title Queen of Crime, and these two show exactly why.
Modern page-turners
Gone Girl by Gillian Flynn is the marriage-gone-wrong thriller whose mid-book twist launched a thousand imitators and a whole publishing trend. The Girl with the Dragon Tattoo by Stieg Larsson pairs a decades-old disappearance with one of the most unforgettable investigators in modern crime fiction. The Silent Patient by Alex Michaelides builds a slow, tightening knot around a therapist and a patient who will not speak, and its ending is the kind people love to argue about.
In the Woods by Tana French brings literary depth and Irish atmosphere to a police investigation, proving crime fiction can be beautifully written as well as gripping. The Thursday Murder Club by Richard Osman is witty, warm, and clever, following a group of retirees solving crimes, and it proves a mystery can be a genuine pleasure as well as a puzzle. Big Little Lies by Liane Moriarty wraps a sharp, character-driven suburban drama around a slowly revealed crime, and The Da Vinci Code by Dan Brown remains the breathless, code-cracking treasure hunt that kept millions of people up far too late.
How to read them without spending a fortune
The classics on this list are free from public-domain archives like Project Gutenberg and Standard Ebooks, so you can start Sherlock Holmes or The Woman in White in the next five minutes at no cost. For the modern titles, your local library almost certainly lends them as ebooks and audiobooks through the Libby app, free with a library card. Working through this entire list need not cost you anything beyond a little patience for the occasional waiting list.
How to choose your next one
Let your mood decide. Want a tidy, satisfying puzzle you can solve along with the detective? Reach for Christie or Sherlock Holmes. In the mood for a modern twist that will leave you gasping? Gone Girl or The Silent Patient deliver. Fancy something warmer and funnier without losing the mystery? The Thursday Murder Club is a delight. Because so many of these are free or borrowable, you can start a few first chapters and follow whichever grabs you hardest.
What makes a thriller unputdownable
It is worth noticing what these books share, because it helps you find more you will love. Almost all of them open with a hook, a question you need answered, and then dole out information at exactly the pace that keeps you turning pages. They give you characters you care about, or love to distrust, and they play fair enough that the ending feels earned rather than cheated. When you find an author who does this well, their whole back catalogue becomes your next several weekends.
Frequently asked questions
Which one should I start with?

Are any of these free?
