The book was the first novel Fforde wrote, however, he failed in its publication. It has been massively re-written following the success of the Thursday Next novels. A follow-up, entitled The Fourth Bear, was published in July 2006.
It's Easter in Reading - a bad time for eggs - and the shattered, tuxedo-clad corpse of local businessman Humpty Dumpty has been found lying beneath a wall in a shabby part of town. Humpty was one of life's good guys - so who would want him knocked off?
