“Sweeps the reader along its breathless, tumbling course …” — Peter Straub, Bram Stoker Award winning author of A DARK MATTER A sociopathic killer is using the internet to lure seemingly random women to their gruesome deaths in New York City. During his heinous murderous spree this madman is extracting the bones of his victims. His sheer brutality has the residents of the Big Apple in panic mode. Who is this twisted psycho who’s abducted a housewife in broad daylight only to dispose of her lifeless body alongside a lake in Prospect Park, nailed the boneless remains of a nameless drifter to the underside of a boardwalk at Rockaway Beach, allowed the gutted corpse of a single parent to wash ashore under the Brooklyn Bridge, and has had the audacity to leave the desecrated body of the Magnolia Tea heiress rotting atop trash at one of the city’s sanitation dumps? NYPD’s top cop, Homicide Commander Lieutenant John W. Driscoll has never witnessed such savagery. Hammered daily by the District Attorney, the Mayor and the Police Commissioner, the Lieutenant, who’s battling his own inner demons, must use every resource available to put an end to the killings. In a race against time, Driscoll, aided by Sergeant Margaret Aligante and Detective Cedric Thomlinson, sets out on a rollercoaster of an investigation to first identify the villainous fiend, and then put an end to his butchering. Peter Straub ~ Bram Stoker Award winning author of A DARK MATTER O'Callaghan has scored his way into the first rank of writers exploring the psychology and methods of serial killers alongside those up their often-troubled opposite numbers, police inspectors. Bone Thief sweeps the reader along in its breathless, tumbling course... just the thing for an autumn evening, a comfortable chair in front of the fireplace, a measure of single-malt Scotch, and, from deep in the surrounding woods the howls of faraway madmen. Gayle Lynds ~ New York Times bestselling author of THE ASSASSINS Sharp as a scalpel, chilling as ice, Bone Thief takes you on a relentless and harrowing ride into the disturbed world of a serial killer who steals his victims' bones. From dark beaches to immaculate hospitals, police back rooms to the mansions of the wealthy, O'Callaghan peels back the layers of the human soul with informed surety. P. J. Parrish ~ International Thriller Award winning author of THE DAMAGE DONE From its chilling opening to its slam-bang conclusion, Bone Thief delivers the goods. You won't soon forget this truly creepy serial killer... or the haunted cop who struggles to bring him to justice. Lynn Hightower ~ Shamus Award winning author of EVEN IN DARKNESS Authentic cop details, a compelling plot, and a twisted killer who'll make you look over your shoulder with every page. Alex Kava ~ New York Times bestselling author of the Maggie O'Dell and Ryder Creed Series Chilling psychological suspense that will leave you at the edge of your seat, white-knuckled and still turning pages. Keep the lights on and lock the doors. Alafair Burke ~ New York Times bestselling author of THE BETTER SISTER With expert pacing and plotting, Bone Thief will keep you riveted until the surprising, satisfying end. Be warned, however... this one should be read in the light of day. Alan Paul Curtis of who-dunnit.com Bone Thief is that rare commodity in murder-mystery fiction which can actually give the reader nightmares. O'Callaghan twists imagination into unspeakable shapes. Lisa Yanaky of bookbrothel.com A strong, sharply written debut...there's a fast paced plot, intrigue, and a smart cop facing off against an evil-but-clever serial killer. O'Callaghan's writing style perfectly reflects the tense plot. Sheila Leitzel of bookfetish.org Riveting, tightly written, an exceptional read.
