Book excerpt: Beware of the Dog is a short, gripping story of life in wartime from Roald Dahl, the master of the shocking tale. In Beware of the Dog, Roald Dahl, one of the world's favourite authors, tells of an injured pilot recovering in hospital who makes a disturbing discovery . . . Beware of the Dog is taken from the short story collection Over to You, which includes nine other dramatic and terrifying tales of life as a wartime fighter pilot, and is drawn from Dahl's own experiences during the Second World War. This story is also available as a Penguin digital audio download read by Cillian Murphy. 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.
