A level 4 Oxford Bookworms Library graded reader. This version includes an audio book: listen to the story as you read. Retold for Learners of English by Patrick Nobes. Dartmoor. A wild, wet place in the south-west of England. A place where it is easy to get lost, and to fall into the soft green earth which can pull the strongest man down to his death. A man is running for his life. Behind him comes an enormous dog — a dog from his worst dreams, a dog from hell. Between him and a terrible death stands only one person — the greatest detective of all time, Sherlock Holmes.
