The house looks like no-one has ever lived there, and the neighbours claim never to have heard of them. Sherlock begins to doubt his sanity until a chance clue points him to Scotland. There the mystery deepens to involve kidnap, bodysnatching and a man who claims he can raise the dead, and Sherlock finds himself in deadly danger.
