NO ONE WILL HEAR YOUR SCREAMS                                                                       


"A fast-paced and compelling read. O'Callaghan depicts a serial killer like no other. Imagine Jeffrey Dahmer, Ed Gein, and Bible John, fused into one heinous beast.  Not all serial killers are the same. Tilden, the evil antihero of this inflammable tale, is compelled by urges that wreak havoc on his human targets. Obsessed by a macabre plan, he implements his sordid designs on the bodies of his multiple victims. He baffles and disorients the forces of law and order- except for Lieutenant Driscoll, whose fervent imagination knows no bounds and whose understanding of evil makes him the prime investigator in this aberrant case. Read this novel, and be haunted!"
-- Anne K. Howard2020 INDEPENDENT PRESS AWARD and 2018 LITERARY EXCELLENCE PENCRAFT AWARD winning author of HIS GARDEN: Conversations With A Serial Killer

"Worth the wait! O'Callaghan is back with a vengeance and this time he delivers a complex but nuanced thriller that grabs you by the throat and never let's go. And that, by way, is a very good thing." 
-- Gregg Olsen, #1 New York Times Bestselling Author of WATER'S EDGE

"No One Will Hear Your Screams is a gritty crime thriller of the highest order. Thomas O'Callaghan has woven a superb neo-noir, carved from the fabric of the likes of Michael Connelly and James Elroy with just enough Don Winslow mixed in for good measure. Bracing when it needs to be, bold when it wants to be and blistering from beginning to end, No One Will Hear Your Screams is sure to leave you screaming for more."

-- Jon Land, USA Today Bestselling Author of the eleven book Caitlin Strong series
"Thomas O’Callaghan’s No One Will Hear Your Screams, features NYPD homicide lieutenant John Driscoll, a man fighting his own demons, on the trail of a diabolical killer who’s unleashed a murderous rampage on the city. Not for the faint of heart, No One Will Hear Your Screams, is coldly graphic in its depiction of the grisly acts of a depraved killer, yet compassionate  in its portrayal of the human heart at war with itself in the pursuit of justice."
-- Con Lehane, author of six mystery novels, his latest being MURDER OFF THE PAGE
"A first class crime thriller:  a fast moving story that never deviates from its goal:  find the killer, stop the killing, save the lives of very vulnerable women."

“The fire-breathing Thomas O'Callaghan has scorched his way into the first rank of writers exploring the psychology and methods of serial killers alongside those of 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.”
--Peter Straub ~ Bram Stoker Award winning author of A DARK MATTER

“Sharp as a scalpel, chilling as ice, Bone Thief, by Thomas O'Callaghan takes you on a relentless and harrowing ride into the disturbed world of a serial killer who steals his victims' bones.

--Gayle Lynds, New York Times bestselling author of The Last Spymaster and The Coil

“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.”

"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."
--Alafair Burke, author of Close Case, Missing Justice and Judgment Calls

"Bone Thief is a strong, sharply written debut from O'Callaghan -- there's a fast-paced plot, intrigue from Driscoll's personal life, and the main requirement of every good thriller: a smart cop facing off against an evil-but-clever serial killer."

"Very few fictional scenarios provide the punch and chills I experienced while reading Bone Thief. Characters and details were realistic and horror penetrated to the marrow."

"Bone Thief is that rare commodity in murder-mystery fiction which can actually give the reader nightmares. Thomas O'Callaghan, the author, manages to surpass writers such as Stephen King, Clive Barker or Dean Koontz with horror of content while keeping you absorbed in the story."
