Once again Arthur Conan Doyle presents a series of cases which baffle the police, but are no match for Sherlock Holmes and his trusty companion, Dr. Watson. In "Black Peter", the peace of rural Sussex is disturbed by the discovery of a seafarer's body pinned to the wall of his hut with a harpoon. In the "Golden Pince-Nez", a young man is found dead clutching a pair of spectacles, yet he had perfect sight.
