John Dickson Carr, one of the masters of the British-style detective novel, evokes the danger and delights of 1912 New Orleans in this puzzling murder mystery Journalist and spy novelist Jim Blake takes an assignment for Harper's Weekly that puts him on a train to New Orleans, where congressional candidate James Claiborne Blake is being targeted by enemies who threaten to reveal that there is a glamorous Creole courtesan in his past. But in New Orleans, a sexual indiscretion is not enough to ruin a politician. That would require murder. When one of Clay's supporters is found murdered, Jim Blake sets out to clear the candidate's name--a dangerous mission in a city that comes alive at night, where rumor can be as deadly as poison.
