A killer is stalking and murdering sorcerers, and Valkyrie Cain is next on his list. While hunting down a cult of magical terrorists intent on taking their revenge on the mortal world, Skulduggery and Valkyrie are drawn into a murder investigation with unsettling similarities to a case they just closed – the case that nearly took the lives of both Valkyrie’s sister and girlfriend. With the body count rising, a special night approaches – a night where the elite of sorcerer society will gather on a remote island to witness a ceremony that could change that society forever.

A murder. A mystery.​ Two murders, actually. Well, three, if you’re counting. Oh, look, here comes a fourth... So much murder that skeleton detective Skulduggery Pleasant must annoy Valkyrie Cain, the infamous Destroyer of Worlds, with his incredible deduction abilities at every available opportunity. As Valkyrie’s irritation grows, the detectives sink deeper into a hidden world of dark motivations, festering hatred and unimaginable pain. ​ And a teensy bit more murder.
