OK, so I admit it, I have read every one of the Prey series - including the couple which haven't quite come up to the usual standard of brilliance.
Davenport and Sloan have both matured extremely well, but in this one they have their edge back (not running over roofs like 21 year olds) - but the caustic humour and the passion are both there. The writing is brilliant, characterisation so believable that Mr Sandford can paint a picture of a country cop - you only meet once - and he is there before you. The twists anad turns of the plot are frustrating and surprising.
The best thing I can say is that it has an ending - not a oh gosh I have run out of words and need to end this ending - a thorough, calculated and well executed ending.
If you have never read any of the Prey series get hold of some of the first ones and make your way through - it's worth it.
Word of caution - do not read the hundred best songs of the rock era at the back of the book - it'll drive you nuts, you won't agree with it, but you will then have to think of your own.
