An illegal immigrant is found murdered in an Edinburgh housing scheme: a racist attack, or something else entirely? Rebus is drawn into the case, but has other problems: his old police station has closed for business, and his masters would rather he retire than stick around. Siobhan, meanwhile, has problems of her own. A teenager has disappeared from home and Siobhan is drawn into helping the family, which means travelling closer than is healthy, towards the web of a convicted rapist. Then there's the small matter of the two skeletons - a woman and an infant - found buried beneath a concrete cellar floor in Fleshmarket Close. The scene begins to look like an elaborate stunt - but whose, and for what purpose?
