98 classic mystery books · free in PDF & EPUB

Locked rooms, unshakeable alibis, and clues laid out in plain sight — classic mystery plays fair and still wins. The whole shelf of detective novels and stories is in the public domain, free to download in PDF or EPUB or to read online, no account required.

The Murder of Roger Ackroyd pulls the trick the genre never recovered from. A Study in Scarlet introduces a certain consulting detective; Arsène Lupin is France's charming answer — a thief instead of a detective — and The Hound of the Baskervilles remains the best campfire story ever disguised as a whodunit.
