The Big Over Easy by Jasper Fforde.
Hilarious police procedural where Inspector Jack Spratt investigates the death of Humperdinck Aloysius Jehoshaphat van Dumpty.
Quote
Meet Inspector Jack Spratt, family man and head of the Nursery Crime Division. He's investigating the murder of ovoid D-class nursery celebrity Humpty Dumpty, found shattered to death beneath a wall in a shabby area of town. Yes, the big egg is down, and all those brittle pieces sitting in the morgue point to foul play...Jack is still stinging from not being able to bring the three little pigs to justice for their wanton murder of Mr. Wolff. He wants to shake his reputation for having a poor solve rate for his cases, so cracking the Dumpty case is important to him.
There's a new pun or allusion every minute ("Thomas Thomm, the son of Reading's premier solo flautist, was convicted in court of stealing a pig last Wednesday.") I'm sure I missed some, so I'd better go back and re-read my Mother Goose. smile
