Barney, Roger, Diane and Snubby love solving mysteries, with the help of Loony the spaniel and Miranda the monkey. A cosy old house surrounded by snow-covered hills seems a perfect place to spend the winter holidays, but the peace is disturbed by unexplained noises. Who could have knocked at the door in the middle of the night, and what is the noise that Snubby hears coming from the kitchen? AUTHOR: Enid Mary Blyton (11August 1897-28 November 1968) was a British children's writer known as both Enid Blyton and Mary Pollock.

Her books have enjoyed popular success in many parts of the world, and have sold over 600 million copies. Blyton is the fifth most translated author worldwide: over 3544 translations of her books were available in 2007 according to UNESCO's Index Translationum she overtook Lenin to get the fifth place and is behind Shakespeare. One of Blyton's most widely known characters is Noddy, intended for early years readers. However, her main forte is the young readers' novels, where children ride out their own adventures with minimal adult help. In this genre, particularly popular series include the Famous Five (consisting of 21 novels, 1942-1963, based on four children and their dog), the Five Find-Outers and Dog, (15 novels, 1943-1961, where five children regularly outwit the local police) as well as the Secret Seven (15 novels, 1949-1963, a society of seven children who solve various mysteries). Her work involves children's adventure stories, and fantasy, sometimes involving magic. Her books were and still are enormously popular in Britain, Malta, India, Pakistan, New Zealand, Sri Lanka, Malaysia, Singapore, and Australia; as translations in the former Yugoslavia, Japan; as adaptations in Arabic; and across most of the globe. Her work has been translated into nearly 90 languages. *
