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. An Oxford Bookworms Library reader for learners of English, adapted from the Sir Arthur Conan Doyle original by Patrick Nobes. Download and start listening now!
