In Arthur Conan Doyle’s Sherlock Holmes story “The Red-Headed League,” the client’s name is Jabez Wilson.
Wilson is a London pawnbroker with conspicuously red hair. He tells Holmes that he was offered a well-paid position copying text for the mysterious Red-Headed League, but the organization abruptly dissolved.
Holmes recognizes that the unusual employment scheme is a distraction. The real purpose is to keep Wilson away from his shop while criminals dig a tunnel from nearby premises toward a bank.
The story is one of Doyle’s most comic and memorable cases because the harmless-looking advertisement conceals a carefully planned burglary. The title refers to the fictional organization, not to a genuine Victorian institution.
