A chilling psychological horror novel by Stephen King that explores the blurred line between creativity and evil. The story follows acclaimed novelist Thad Beaumont, who secretly wrote a series of violent bestselling crime novels under the pseudonym George Stark.

When Thad publicly "kills off" the George Stark persona and reveals the truth about his pseudonym, a series of gruesome murders begins. The evidence points toward George Stark himself—a man who should not exist. As Stark becomes terrifyingly real, he sets out to destroy everyone connected to Thad, forcing the author into a deadly confrontation with his own dark alter ego.

Blending supernatural horror, psychological suspense, and crime fiction, The Dark Half examines themes of identity, duality, artistic creation, addiction, and the hidden darkness within the human mind. Inspired in part by Stephen King's own experience publishing under the pseudonym Richard Bachman, the novel offers a fascinating meditation on the relationship between an author and their fictional creations.

The novel also introduces Sheriff Alan Pangborn, who later returns as a central character in Needful Things.
