England, 1738. On the trail of a lost book, the Doctor and Charley arrive at the beautiful country estate of Sir Ralph and Lady Sybil. But all is far from idyllic.

Something that could destroy the very fabric of reality. The Doctor and Charley have just forty-eight hours to solve the mystery before the whole world succumbs to The Doomwood Curse.
