As they end the river boat journey they began in Death on the Mississippi, Twain and Cabot arrive in New Orleans to do a couple of lectures, and to finish some research for Twain's next book.
They arrive just in time to read about a murder of a prominent white politician running on the reform ticket. The murderer is his cook, or so the police say. A friend of Mark's begs him to prove the man innocent.
Thus begins another story in the career of Mark Twain Detective. I enjoyed this one as much as the first, and once again was not able to identify the guilty one until Mark leads the real murderer into a trap.
