Carter, one of the world's leading experts on Dracula, owns many editions of Bram Stoker's novel, maybe even as many as his well-heeled rival, Mikaela Klove. But one thing has always eluded him: the chance to examine the possibly apocryphal blue edition of Stoker's seminal vampire tale. If it actually exists, the elusive edition is rumored to contain a different ending and a never-before-published chapter tantalizingly set in Dracula's personal library.

Determined to read it for himself, Carter travels to Transylvania, where the rumoured treasure might be hidden. But once there, he'll need to work with his nemesis to solve the mysterious puzzle – or risk an endgame neither he nor Mikaela can afford to lose.

Drawing on his renowned flair for the outré, Christopher Fowler – an author 'in the first rank of contemporary mystery writers' – reimagines Stoker's lost chapter and intersperses it with an unforgettable journey through Transylvania.
