Every missing husband has a secret. Some are worth killing for.

When wealthy socialite Ruth Bates walks into Jack Marconi’s PI office, she claims her husband is missing. But in Albany’s underworld of cartels, crooked politicians, and country club secrets, nothing is ever that simple.


What starts as a routine case soon plunges Marconi and his partner Blood into a nightmare of sex trafficking rings, brutal cartel enforcers, and a mansion hiding horrors behind its polished doors. The deeper Marconi digs, the more he realizes Ruth may not be a victim at all—but a femme fatale playing a deadly game.

Raw, dark, and unflinching, Ruthless delivers classic pulp-noir grit with modern stakes. Fans of Michael Connelly, Don Winslow, and Lee Child will tear through this relentless thriller from New York Times bestselling author Vincent Zandri.
