If Conan Doyle can't solve the deadly curse that's attacking the Ghost Club, can Evie Winstanley do any better?

London, December 1904. After setting up an occult detective agency, Evie is finding supernatural cases are thin on the ground. She's almost out of money when Arthur Conan Doyle appears with a case: to investigate the recent horrifying deaths of members of the Ghost Club, a secret society devoted to the paranormal.

Pulled into a world of spectres and secrets, Evie turns to Kit-a reluctant psychic whom she once turned down. He wants nothing to do with the supernatural, but as the bodies mount and the veil between worlds thins, Evie needs him. And perhaps, despite himself, Kit needs her too.

Together, they uncover a conspiracy that extends from wild parties in Belgravia to the shabby streets of Soho. Behind it all lurks a dangerous occult magician, ready to destroy anyone who gets in his way. He knows what Evie's capable of. And it seems he has a plan - to lead her down with him into darkness.

Domain of Darkness is a chilling gothic mystery steeped in yearning, menace, and the world of the unseen.
