Mark Twain’s ghost has come to you seeking help from an evil that has been stalking him in the afterlife. Trace the steps in Twain’s past that led to a lifetime of anguish.

After waking an unexpected evil, Twain sets about to rid his time of the darkness, but the plot only thickens. With Twain’s help, you have to unravel the connections to try and set history straight while dangerous forces loom.
