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.

'Dahl is too good a storyteller to become predictable' Daily Telegraph

Roald Dahl, the brilliant and worldwide acclaimed author of Charlie and the Chocolate Factory, James and the Giant Peach, Matilda, and many more classics for children, also wrote scores of short stories for adults. These delightfully disturbing tales have often been filmed and were most recently the inspiration for the West End play, Roald Dahl's Twisted Tales by Jeremy Dyson. Roald Dahl's stories continue to make readers shiver today.
