ARGONAUT BOOKS

An ill-fated grave-robbery unearths a corpse with a most disturbing symbol on it. The very same sign is daubed in blood on the walls of Edinburgh's lunatic asylum, on the night that one of the patients is murdered. The mark in question? The mark of the devil. The prime suspect: Amy McGray, the asylum's most infamous inmate, a young woman who has grown up behind bars after she killed her parents many years ago. Her brother, Detective 'Nine-Nails' McGray, knows the evidence is stacked against her. And, to prove her innocence, he needs the help of an old friend.
