Short on pocket money, Frank and Jess decide to open a business known as Own Back, in which they seek revenge on past wrongs for their clients. Secretly they hope to find a way to punish the neighbourhood bully Buster Knell, and so it is a grim task when they find he is their first client. His demand? That they remove a tooth from Vernon Wilkins, the large boy that did the same to him. But this job goes horribly wrong when a simple tooth creates more unwelcome employment for them: two strange little girls who want their house back, Buster Knell's entire gang, and even the strange Biddy Iremonger, who is certainly a witch!
Components of Wynne Jones's style is still intact - her quirky way of speaking (newcomers might be confused at the quite literal 'colouful language' that Buster uses) and her intricate melding of several plots and people. But I feel that had she written it today, there would have been deeper reasoning behind Biddy's revenge tactics, more Own Back business for Frank and Jess, an explanation behind the "good eyes" that Jess is given, and a more sophisicated plot for finally getting rid of the evil witch. However, "Witch's Business" is humourous, interesting, and serious enough for Wynne Jones fans to enjoy and compare with her later books (I saw touches of "Time of the Ghost" and "Black Maria" in the plot) and just as good for new readers to find a new favourite author. They're the lucky ones, gifted with the knowledge that from here, Wynne Jones's work just gets better!
Frank and Jess's dad stops their pocket money when they accidently break a chair. Desperate for money (especially since Frank owes the vicious bully Buster Knell), they begin "Own Back Limited." Their first customer? Buster and his gang. Buster has had a tooth knocked out by Vernon Wilkins, and wants the Own Back kids to knock out one of Vernon's, as payment for Frank's debt. When they tell Vernon, he gets a baby tooth from his little brother (so it's still "Wilkins' tooth"), and all seems to be right with the world at first.
The problem is that soon a pair of peculiar little girls insist that the Own Back kids do something nasty to Biddy Iremonger, a weird old lady -- because they say she put a spell on the younger girl. At first Frank and Jess won't. But when Vernon's little brother becomes horribly ill, they discover that Biddy really IS a witch. And what's more, she's not too pleased about their little business...
This was Jones' first book, and it shows. There are some problems that were ironed out in her later novels, but there is also a sprightly unself-conscious quality to it. She builds up the menace of Biddy, making you wonder if she really is a witch at first, then revealing it in a matter-of-fact way that makes you feel almost as shocked as Jess and Frank.
Unfortunately, there are some distracting parts of the book -- the G-rated profanity of the bullies ("eyesballs in salsa"?) isn't particularly convincing. And the animosity of some of the characters is sort of brushed away and not really dealt with again again. And the supporting cast aren't as well-defined as her later characters are; they tend to blur together at times.
Frank and Jess are acceptable lead characters -- they seem a little too alike at times, although they become much more different by the last part of the book. Buster is a by-the-book bully, but one who thankfully is somewhat redeemed. Vernon is a likable guy, and Frankie, Jenny and Martin are somewhat more anemic.
Despite its flaws, "Witch's Business" is still a clever little fantasy mystery with plenty of weird magic, persistent British preteens, and a humorous finale.
