The Devil Has Come to Edinburgh...\n\nAn 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.\n\nThe mark in question? The mark of the devil.\n\nThe 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.\n\nHer brother, Detective 'Nine-Nails' McGray, knows the evidence is stacked against her. To prove her innocence, he needs the help of an old friend...\n\nInspector Ian Frey insists he is retired. But when called upon, he reluctantly agrees to their final case.\n\nBecause this is the case in which all will be revealed - as twists follow bombshells on the way to the secrets that have been waiting in the shadows...\n\nThis rollicking Victorian sensationalist melodrama is the epic conclusion to the marvellous Frey & McGray myste.
