"An interesting, yet brief, message," Holmes mumbled, tapping the letter with the stem of his pipe. "We shall take the eight-seventeen out of Euston and head for the city of Carlisle, in the county of Cumberland, tomorrow." The daring theft of the Arroyo Drums from the Border Regiment brings Sherlock Holmes and the loyal Dr. Watson to Carlisle on their latest adventure. Martin Daley has picked up Sir Arthur Conan Doyle's pen to communicate a case which has never before been brought to the notice of the public. A case that brings fact and fiction, including original photographs, together into a seamless new adventure for Sherlock Holmes set in Carlisle in October 1903.
