Topping and tailing this collection are "The Visitor and "Bitch", stories featuring Dahl's notorious hedonist Oswald Hendryks Cornelius (or plain old Uncle Oswald) whose exploits are frequently as extraordinary as they are scandalous. In the middle, meanwhile, are "The Great Switcheroo" and "The Last Act", two stories exploring a darker side of desire and pleasure. In the black comedies of "Switch Bitch", Roald Dahl brilliantly captures the ins and outs, highs and lows of sex.
