The first in a series of 7 crime books, so far, starring Inspector Ian Frey and Detective 'Nine-Nails' McGray. Set in Edinburgh in 1888 Frey is sent from Scotland Yard in London to help McGray, in his new but fake department investigating the occult, investigate the murder of a viruoso violinist who was murdered in his own home in a locked room with no other way in or out.
This was better than I expected and I learned a lot about violins and catgut - wait to you read about that! I also enjoy the 1800's and being set in Edinburgh made a change from Victorian London. McGray seems to believe in the occult but his backstory emerges through the book and all becomes clear in the end.
The characters are well drawn the plot is a pot-boiler and the prose is very well written.
It was a page turner and it has stayed with me for quite a while.
