Fan CastingFrey and McGray series

Edinburgh, 1888. A virtuoso violinist is brutally killed in his home. Black magic symbols cover the walls. The dead man's maid swears she heard three musicians playing before the murder. But with no way in or out of the locked practice room, the puzzle makes no sense... Fearing a national panic over a copycat Ripper, Scotland Yard sends Inspector Ian Frey to investigate under the cover of a fake department specializing in the occult. However, Frey's new boss - Detective 'Nine-Nails' McGray - actually believes in such nonsense. McGray's tragic past has driven him to superstition, but even Frey must admit that this case seems beyond reason. And once someone loses all reason, who knows what they will lose next.
