NEW ORLEANS, 1919. For nearly a decade, a ruthless killer has prowled the streets of this city, breaking into homes in the middle of the night and hacking people to death with an ax. He leaves few clues. Even his motives are unclear. The police are baffled. The killer even writes a letter to a local newspaper--echoing Jack the Ripper from three decades earlier--and claims to be a "demon from hottest hell."
But Detective Colin Fitzgerald, a wounded veteran only recently returned from the Great War, is prepared to do whatever it takes to catch this killer. What Fitzgerald is not prepared for are the shocking secrets his investigation will uncover, secrets that stretch to the top levels of the Police Department and City Hall, and reach back decades to the assassination of a legendary police chief and to the murder of Fitzgerald's own father.
