Down in the Zero

Andrew Vachss has reinvented detective fiction for an age in which guilty secrets are obsolete and murder isn't even worth a news headline. And in the person of his haunted, hell-ridden private eye Burke, Vachss has given us a new kind of hero: a man inured to every evil except the kind that preys on children.
Now Burke is back, investigating an epidemic of apparent suicides among teenagers of a wealthy Connecticut suburb.  There he discovers a sinister connection between the anguish of the young and the activities of an elite sadomasochistic underground, for whom pan and its accompanying rituals are a source of pleasure—and power

Burke's newest client is a woman named Flood, who has the face of an angel, the body of a high-priced stripper, and the skills of a professional executioner. She wants Burke to find a monster for her—so she can kill him with her bare hands.
In this cauterizing thriller, Andrew Vachss' renegade private eye teams up with a lethally gifted avenger to follow a child's murderer through the catacombs of New York, where every alley is blind and the penthouses are as dangerous as the basements. Fearfully knowing, crackling with narrative tension, and written in prose as forceful as a hollow-point slug, Flood is Burke at his deadliest—and Vachss at the peak of his form.
