I love true crime and of course, know John Douglas' name well. I ordered this, not realizing until I was running out the door with it in hand to read on the subway that it was a novel. I was a little disappointed, because I generally am more interested in true stories. I did read the whole book and I enjoyed it. I am guessing that there is probably a lot of John Douglas in the main character (Jake Donovan - same initials, even). The idea of the Flying Squad on which the book is based, is fascinating. And, of course, solving the mystery is half the fun. Well written, a good story, believable characters and even a few good chuckles.
