The Witches

Enhanced descriptions from Syndetics:

BEWARE.
Real witches dress in ordinary clothes and look like ordinary women. But they are not ordinary. They are always plotting and scheming with murderous, bloodthirsty thoughts - and they hate children.
The Grand High Witch hates children most of all and plans to make every single one of YOU disappear.
Only one boy and his grandmother can stop her, but if their plan fails the Grand High Witch will frizzle them like fritters, and then what . . . ?

Booklist Review

Gr. 4-6. One of Dahl's best about a boy who is turned into a mouse, but who nevertheless takes on the Grand High Witch of the World. Funny, yes, but a little scary as well.

Kirkus Book Review

By a talky, roundabout route, Dahl slyly (if deterringly) takes the narrator--ostensibly himself at seven--into the delicious, ambiguous situation of being a mouse-boy. . . who turns the tables on his tormentors. We first hear about witches: they spend their time plotting to get rid of children, ""they all look like nice ladies,"" they are difficult but not impossible to spot. Then, we hear about Dahl's cigar-smoking Norwegian grandmother, who told him about witches and how to spot them: they all wear wigs to cover their bald heads, for one thing, and have itchy scalps. So, when Dahl and his grandmother are at a Bournemouth hotel, and the lady-delegates to the Royal Society for the Prevention of Cruelty to Children conference start scratching away (p. 57), Dahl is wary. Then the pretty head lady takes off her mask: the Grand High Witch incarnate! To demonstrate her Formula 86 Delayed Action Mouse-Maker, she's already fed some to greedy, obnoxious little Bruno Jenkins--who turns into a mouse on schedule. Will Dahl be detected, hiding behind a screen? He hasn't washed in days, but some of that tell-tale child-scent, anathema to witches, escapes. Forcefed the potion, he joins Bruno scampering about the floor--but they still have their own voices, and his wonderful witchophile grandmother will know what to do. Actually, Dahl's wits have if anything sharpened. With his grandmother as a confederate, he steals a bottle of the potion; pours it into the witch-delegates' soup tureen; and has the exquisite pleasure of seeing them turned into mice, to be wiped out on the spot. (Bruno meanwhile is contentedly munching away--to the horror of his mouse-hating parents.) When last seen, DaM and his grandmother are quietly resettled in Norway--where he wonders if she'll live out Ms short mouse-life span, and she's plotting to get rid of the world's remaining witches. A (quicker-acting) sequel is to be eagerly expected. Copyright ©Kirkus Reviews, used with permission.
