From out of the grave. London, 1888: Agatha drags herself from a shallow grave to roam the fog-shrouded streets of the dark city, trying to piece together what happened.

As her memory grows stronger, the hazy images from her past come into focus, but questions remain. Do her answers lie in the shadows of the streets, the hidden corridors of London Hospital, or someplace far more frightening?
