'And in Edinburgh of all places. I mean, you never think of that sort of thing happening in Edinburgh, do you...?' 'That sort of thing' is the brutal abduction and murder of two young girls.

After the brutal abduction and murder of two young girls, now a third is missing, presumably gone to the same sad end. Detective Sergeant John Rebus, smoking and drinking too much, his own daughter spirited away by his estranged wife, is one of many policemen hunting the killer.
