The Strange Case of Dr. Jekyll and Mr. Hyde by Robert Louis Stevenson (1886). This novel might easily have become a victim of its own surpassing fame, which has removed all suspense from its central riddle: What is the relationship between Dr. Jekyll and Mr. Hyde? Yet as our narrator plumbs Dr. Jekyll’s descent into drug-addled, alter-ego madness, we are riveted by Stevenson’s portrait of the good and evil that lurks in one man’s heart. “This, too, was myself,” Jekyll says of Hyde. Somehow we suspect it’s us, too.
