On a notorious street where propriety and decadence clash, in the basement of a newly renovated bar, the bones of a woman and child are discovered beneath a cement floor. It's an unusually gruesome find, even for Fleshmarket Alley. When Inspector John Rebus is called to investigate, every fact he finds unleashes a host of new questions. Are the bones those of a mother and child? Are they actual human remains or fakes? Were they planted there - and if so, why?It could be nothing more than a ruthless and enterprising pub owner looking to create a local legend that will help lure trade. Or it could be something far worse - something as grisly as the death of a recent immigrant found brutally murdered at a local housing project, or the murder of Donald Cruikshank, a recently paroled rapist whose body is found just as a young woman goes missing. The missing girl is a friend of Inspector Rebus's colleague Detective Siobhan Clarke, and Siobhan is shocked to find herself in the same intricate web of murderers as Rebus - all somehow tied to that pile of bones under Fleshmarket Alley.In a race to stop the killings before more bodies turn up - even as the possibility of romantic entanglements distracts and entices them - Rebus and Siobhan plumb the darkest corners of their beloved city and confront the lawless, conscienceless men who dwell there. Writing with the unstoppable narrative force that has made him one of the bestselling writers in the world, Edgar Award-winner Ian Rankin delivers his most explosive and surprising mystery yet.
