1881, New York City, and the word on the street pointed to the Wolves as the worst of the worst gangs. Their captured leader was sent to Sing Sing State Prison up the Hudson river, but made an astonishing escape. The frustrated police superintendent calls in private detective Joe Phenix to hunt the man down.
Led by an androgynous mastermind called Captain Molly, whose mastery of disguise matched even the skills of Joe Phenix, the Wolves were a cold-blooded gang of criminals. Captain Molly was born of the Romani people, “Gypsies,” a situation that in turns helps him and also helps his pursuer, the famous detective.
The mysterious Queen of the Gypsies guides with predictions, and Joe Phenix lives among the Romany to learn their ways while chasing Captain Molly through the most wealthy and the most foul parts of New York City.
