Devil's Heaven — Thomas Adcock

Fresh from his ancestral Irish home with a new bride, old ghosts, and a terrible thirst, Hockaday is drawn into a vicious homicide case. A spate of homosexual deaths around New York City, written off by the police as suicides, are soon revealed to be the work of a brutal serial killer. Hock, furloughed from the force and battling the bottle, stays on the case as a private eye. From Madison Avenue to the Metropolitan Opera to the extravagant gay nightlife scene; from the city's Russian mafia to a West Side sex club; the soulful detective is discovering a Celtic cross of personal redemption, slaughter, secrets, and vengeance. And the tide of blood is rising fast.
