The final Sherlock Holmes novel opens on a cipher, a murder at a moated Sussex manor with the victim's face destroyed by a shotgun, and the shadow of Professor Moriarty — then breaks, halfway through, to a Pennsylvania coal valley where a secret society rules the mines by terror. Conan Doyle drew that second half from the real Molly Maguires and the Pinkerton agent who broke them, and the two stories are finally one. This edition presents the complete and unabridged novel, newly typeset and illustrated with 31 full-page color plates.
