A Scotland Yard Inspector hunts something more dangerous than werewolves through the gaslit streets of London.
Royston Jones, unacknowledged bastard of a high-born family, is determined to track the killer before more young women fall to his knife. But his investigation puts him in the way of a lord who is a clandestine werewolf and the man’s fiancée , a woman alchemist with attitude and a secret of her own.
Will they destroy Royston to protect their covert identities, or will they join with him to hunt the hunter?
