A multimillion-dollar bounty brings out every vigilante in New York . . . “Chilling psychological suspense that will leave you at the edge of your seat.” —Alex Kava, New York Times–bestselling author of the Maggie O’Dell series Tourism in New York City is under siege. Visitors to the Big Apple have become targets of a pair of vengeful twins bent on exacting punishment on total strangers to right the wrongs perpetrated against them in a hellhole they called home. Their audacious killing spree leaves men and women of all ages and ethnicities brutally murdered then scalped, their lifeless forms displayed in macabre fashion at landmarks throughout the metropolis. NYPD Homicide Commander John W. Driscoll, along with his dedicated team of Sgt. Margaret Aligante and Det. Cedric Thomlinson, is determined to bring the pair to justice—as is a despicable grieving father whose idea of justice is at odds with morality itself. By offering a three million dollar bounty, not a cent of which he plans to part with, he’s turned the city into a get-rich-quick circus, with an overzealous mayor acting as ringmaster to please Mr. Moneypockets any way he can. And Driscoll—who’s been assigned the case just hours after he buried his wife—must put his grief on hold and focus on shutting down the twins’ reign of terror by apprehending them before their denouement is dictated by an unscrupulous and unforgiving interloper . . .

Thomas O'Callaghan drew rave reviews for Bone Thief, chilling debut. Now, in his riveting new thriller, a diabolical killer is terrorizing New York City. . . The Screaming Room John Driscoll has laid the ghosts of his past to rest. He's ready to start over--both personally and as a New York City homicide detective. But it seems that a serial killer has other plans for Driscoll. The victims' bodies are found, brutally mutilated and carefully arranged. Someone has displayed the corpses for the world to see: on a Ferris wheel; in a dinosaur diorama; on a bridge--grotesque visions to all except for the depraved killer, who considers them masterpieces. These blood rituals spell out a message to Driscoll. And they are just the beginning. . . Driscoll's investigation will lead him down the darkest of journeys, toward an evil beyond his worst nightmares. In a hellish landscape conceived by the all-too-clever mind of a twisted schemer, Driscoll must play a killer's deadly game. It's up to him to save his city--or die trying.
