Reviews for 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. Howard, 2020 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."
Pat Mullan, Ireland's Chair of The International Thriller Writer's Association and author of A DEADLY GAMBLE

“Thomas O’Callaghan has created a dark, compelling novel filled with thrills, kills, twists and turns that feel so real you’ll be scared to read it alone. Police procedurals don’t get much better than this. I highly recommend it.” 
Alex Shaw, #1 International Kindle Bestselling author of the Aidan Snow, SAS thriller series.

She Just Loves Books

Cheryl’s Book Nook

"O’Callaghan delivered with an unthinkable sociopathic killer that had me squirming in fear for this character. The plot is razor sharp and the story pacing moved quickly with the short chapters that I really enjoyed."
Nurse Bookie

"This author has a very vivid and scary imagination that will terrify you. It’s one of those books that you can’t put down! The story unwinds and has a cast of characters all entwined together. You have to keep track and pay attention from word one through the end.”
Sandie Vega, NetGalley

The Good Men Project
