Basically, this is the kind of book where your reaction to the title and/or cover is a pretty good indicator of whether or not you'll enjoy the contents. It's silly stuff, sometimes dark, but mostly the kind of outsize fantasy/comedy British writers seem to manage to handle so well (Rankin is often mentioned in the same breath as Terry Pratchett and Douglas Adams). The concept at work here is that a serial killer is on the loose in a city populated by toys, striking down the rich and famous -- namely notables from nursery rhyme fame, such as Humpty Dumpty, Little Boy Blue, et al. Into this killing zone stumbles Jack, a 13-year-old boy come to "seek his fortune" in the big city. But almost immediately upon his arrival, the big city seeks his fortune instead, leaving him mugged and penniless in an alleyway. Fortunately, a kindly teddy bear named Eddie comes along to take him under his paw and get him involved the mystery. It seems Eddie is the sidekick of Toy City's eminent detective Bill Winkie (aka Wee Willie Winkie), who has gone missing. Soon Jack and Eddie are racing across Toy City in clockwork cars, checking out murder scenes, visiting Madam Goose's house of ill repute, and getting sloshed at Tinto's Bar, as they attempt to solve the case. If this sounds somewhat reminiscent of the 1988 film "Who Framed Roger Rabbit?", it should.
Part of the fun comes from the spoofing of nursery rhymes and childhood toys, including comically gruesome murders, thriller/noir goofing, and totally tongue in cheek action. The other part of the fun comes from the wacky wordplay. Rankin is fond of alliteration, punning, double-entendres, repetition of stock phrases, and from the mouth of Eddie, the incomplete simile. If there's one thing one will remember from this book it's the construction "It's as good as!" or "I was scared as!" It has to be said that the book runs on about 50-100 pages too long as the jokes start to wear a bit thin and the action starts to get too repetitive. Alas after all the buildup, the mystery itself is a bit of a shaggy dog story, and somewhat of a letdown. It is fairly inventive stuff, and kind of fun for the most part, but unless you think the title is hilarious you probably won't love the book.
