The Scarifyers: The Nazad Conspiracy (1)

Ghost story writer Professor Dunning doesn't believe in the supernatural. So he's more than surprised when an invisible winged demon appears in his drawing room.

The Metropolitan Police's longest-serving officer, Inspector Lionheart, doesn't believe in the supernatural either, wings or no wings. So he's less than impressed when Russian emigres begin dying impossible deaths all over London.

Together, Lionheart and Dunning must face quarrelsome generals, sinister clowns and Russian demons as they unravel the Nazad Conspiracy.
