By day, Dr. Henry Jekyll is everything Victorian London admires: a celebrated physician, generous benefactor, respected gentleman, and trusted friend. By night, he slips through the back door of his own home in secondhand clothes and disappears into another London, where reputation means nothing and the appetites he keeps hidden are allowed to breathe. Jekyll has spent years perfecting the separation between the man the world sees and the man no one can know. Then a dangerous idea occurs to him: What if the separation could become real? What if chemistry could divide a man as cleanly as it divides any other compound—and allow each half to live without answering for the other?

In this expansive reimagining of Robert Louis Stevenson’s 1886 classic, Sevastian Winters returns to the fogbound streets, locked doors, laboratories, secrets, and moral contradictions of Victorian London while digging deeper into the men at the heart of the story. Henry Jekyll’s experiment does not create the darkness inside him. It gives that darkness a name, a face, and freedom. And as Gabriel Utterson begins assembling the disturbing pieces surrounding his oldest friend, the question becomes not simply who Edward Hyde is—but how much of Hyde was always Henry Jekyll.

The Strange Case of Dr. Jekyll and Mr. Hyde is a dark, character-driven Gothic novel about reputation, appetite, friendship, self-deception, and the terrible consequences of believing we can separate ourselves from the things we choose to do. Familiar in its bones but newly imagined in its depth, it invites readers back into one of literature’s most enduring nightmares—and asks a more unsettling question than whether every good man has an evil side: What happens when a man decides his evil side deserves a life of its own?
