A young girl's mutilated body is discovered in a sealed room. Her remains are carefully arranged, in what seems to have been a cruel and macabre ritual, which appears to have taken place over 60 years ago.
For newly appointed Edinburgh Detective Inspector Tony McLean this baffling cold case ought to be a low priority - but he is haunted by the young victim and her grisly death.
Meanwhile, the city is horrified by a series of bloody killings. Deaths for which there appears to be neither rhyme nor reason, and which leave Edinburgh's police at a loss.
McLean is convinced that these deaths are somehow connected to the terrible ceremonial killing of the girl, all those years ago. It is an irrational, almost supernatural theory.
And one which will lead McLean closer to the heart of a terrifying and ancient evil . . .
What you might not know is that as well as loving romance novels I also love a good crime novel. Being a Scot I also have a really big soft spot for the wonderfully dubbed 'Tartan Noir'. James Oswald is a name that I'd heard a lot in relation to this sub-genre so when I saw the first of his Inspector McLean novels in the library I couldn't help but grab it.
