The giraffe, the pelican and the agile monkey set out to prove that they are the best window-cleaning company around. This edition has some new facts about Roald Dahl, and a great new cover featuring Quentin Blake's illustrations.

Roald Dahl ( 13 September 1916 � 23 November 1990) was a British novelist, short story writer, and screenwriter.
Born in Llandaff, Wales, to Norwegian parents, Dahl served in the Royal Air Force during the Second World War, in which he became a flying ace and intelligence agent. He rose to prominence in the 1940s with works for both children and adults, and became one of the world's bestselling authors. His short stories are known for their unexpected endings, and his children's books for their unsentimental, often very dark humour.
Some of his more well-known works include James and the Giant Peach, Charlie and the Chocolate Factory, Fantastic Mr Fox, Matilda, The Witches, and The BFG.
