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.
