Sherlock Holmes is recruited by the Reverend Augustus Merridew to investigate the recent death of a young child. Merridew is concerned that with rumors going about his village, violence may erupt at any time. The dead child, a mere baby, belonged to an old school mate of Dr. Watson, Rob Ferguson and his new wife, the South American born Carlotta. The problem lies with a recent arrival in the village, Mr. John Sinclair Stockton, whose family had been run out of the village over a hundred years ago. The rumor sweeping the village is that Stockton, like his ancestors, is a vampire and that it was he who caused the baby's death. Holmes and Watson travel to the village and search for a more rational explanation to a series of bizarre events that is haunting everyone.
