Holmes and Watson investigate a mysterious tenant which leads them to a Mafia-like Italian criminal organization. Codes, strange signals in the night and violence highlight this story. The story is notable as the last appearance in the canon of Inspector Tobias Gregson. Also featured is a Pinkerton detective named Leverton. Holmes refers to him as "the hero of the Long Island cave mystery". There is no explanation of that mystery in this story or in later ones.
