#4 The Fourth Bear by Jasper Fforde

This is a sequel to The Big Over Easy. I have read all of Fforde's books and this one is just as good as all the others. The book starts about 6 or so months after the the nursery crimes division solving of the murder of Humpty Dumpty. Of course this means the team is all ready back in disgrace A villain mentioned in passing in The Big Over Easy is the main villain in this book. You get to find more out about Jack and more stuff about Ashley as well. I also have to recommend the author's website since he has so much good stuff listed on there as well that goes with his books. http://www.jasperfforde.com/
