(Book)

Edinburgh, 1888. A violinist is murdered in his home. The dead virtuoso's maid swears she heard three musicians playing in the night. But with only one body in the locked practice room - and no way in or out - the case makes no sense. Fearing a national panic over another Ripper, Scotland Yard sends Inspector Ian Frey to investigate under the cover of a fake department specialising in the occult, but even Frey must admit that this case seems beyond reason...
