Knots and Crosses by Ian Rankin
It is many years since I was first introduced to John Rebus, the detective created by Ian Rankin in his novels set in Edinburgh. It was just as long since I had first read Knots and Crosses the first of the series. It recently came up my back to read it again and, like all good fiction, it has stood the test of time.
In Knots and Crosses, Rebus is confronted by the brutal abduction and murder of two young girls. He then hits John Rebus particularly hard as his own young daughter has been spirited away south by his estranged wife.
Rebus, heavy smoking and drinking too much, is one of many policemen hunting the killer. However, when messages begin to arrive: knotted string and matchstick crosses these taunt Rebus and he becomes aware that this is a puzzle only he can solve.
It is a tautly written thriller that I thoroughly enjoyed. If you enjoy this genre, I recommend Knots and Crosses.
