"Quietly annoying and tenacious" Sheriff John Le Brun has earned a reputation for solving wickedly complex crimes, from his home town of Brunswick, Georgia to London, England. Now retired, he finds himself mysteriously hired to solve the 1908 murder of the owner of a high-priced Manhattan brothel. The client's letterhead indicates J. P. Morgan. The Titan of Wall St. denies its validity but himself hires Le Brun to not only solve the crime but also expose the impostor.

As John peels away layer upon layer of facts, he realizes that he is exploring the police-protected vice of prostitution, which is a source of livelihood for one out of every three hundred women in New York City. Le Brun discovers a connection on St. Simons Island, where he holds a membership to an exclusive club. The island was the locale of the last illegal U.S. importation of African slaves. Now history may be repeating itself, for the purpose of sex slavery.
