The Great War is over. Gangsters run the streets. The jazz is loud. And something darker than crime is moving through the alleys — people disappearing, strange symbols appearing on walls. Sam Marlowe, a retired soldier turned private detective, takes a case that may cost him more than his life. Reluctantly teaming up with Elo, the spirited daughter of the city's mayor, he begins unraveling a city-wide conspiracy involving secret societies, occult forces, and a shadowy organization with a sinister agenda threatening to consume the soul of Brooklyn.
