The Charnel House Trilogy is a trio of games which comprise a continuous story. They are point-and-click adventure games, set in a mystery/horror mood, with some twists in the mix.
The story follows two main characters — Alex Davenport, a young woman preparing to leave home on a life-changing journey, and Doctor Harold Lang, about to board a train going in the same direction as Alex. Along with a couple other characters, the story unfolds throughout the three games as it starts interconnecting everything.
The second game of the three, Sepulchre, was the inspiration for this game and a version was already made available separately in 2003, free of charge.
