Five short classics for a quiet weekend: Stevenson’s tale of a doctor and his darker double, Hawthorne’s story of guilt in Puritan New England, London’s Yukon adventure, Wharton’s spare winter novella, and Conan Doyle’s first Sherlock Holmes collection. Each book is free to read in the public domain, short enough to finish in a few sittings, and strong enough to stay with you long after the weekend ends.
