A locked door is broken open. A body is discovered. And among the papers left behind lies an account that threatens everything Utterson thought he knew. Across London, old certainties begin to crumble as an impossible story emerges from the shadows. Set in the foggy, cobblestone streets of London, lawyer, John Gabriel Utterson investigates the mysterious relationship between his old friend, Dr. Henry Jekyll, and a sinister man named Edward Hyde. What begins as a troubling mystery surrounding a suspicious will, quickly spirals into a dark exploration of science, morality, and the duality of man. The Haunted Library is open. Come in. Stay awhile.
