Knots and Crosses

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. And 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. Then, the messages begin: knotted string and matchstick crosses taunt Rebus with a puzzle only he can solve.
