"Dr. Henry Jekyll, fascinated by the dichotomy of good and evil, no longer wants to inhibit his dark side. He concocts a potion to create the alter ego of Mr. Edward Hyde. With the burden of evil placed on Hyde, Jekyll can now take pleasure in his immoral, nefarious fantasies-- free of conscience and guilt. It's when Hyde turns to murder that Jekyll realizes how monstrous his impulses are and how hard they are to suppress"--Back cover.
