He’s going to kill you. He just doesn’t know it yet. The Queen of the dark, nerve-shredding thriller is back. And she’s outdone herself with this one. With a tagline like the one above I knew I was in for a twisted treat. Dark, depraved, disturbing and deadly, this book took me to some deeply unsettling places in one of the best and most malevolent thrillers I’ve ever read. Profile K is an office urban legend at Netco. Something for staff to whisper about to one another over the water cooler. But when data analyst Midnight Jones comes across a so-called Profile K she discovers someone unlike anyone she’s profiled before. This applicant is troubling and dangerous. A ticking timebomb of murderous intent walking among us. Midnight takes the profile to her superiors, only for them to dismiss her concerns and tell her to forget what she saw. But she can’t and Midnight remains haunted by what this person is capable of. And when a woman is found brutally murdered, she is sure that Profile K is behind it. How can she make people listen before he kills again? A tableau of horror, this is a story painted in blood and violence that has malice dripping from every page. Fields sets the tone from the start with a brutal first chapter that made my blood run cold. She moves between the multiple narrators to tell the story, building an atmosphere of ominous foreboding as we peek inside the daily lives of Profile K’s victims. And it is those victims through whose eyes we see their murders, their terror and pain palpable as the monster strikes and they finally discover their terrible fate. This is a dark thriller-lover’s dream, filled with grisly crime scenes, heart-stopping suspense, surprising twists, and a cold-blooded killer who puts the ‘psycho’ in ‘psychological thriller’. I devoured this one whole, unable to put it down for even a moment once I’d started. Helen Fields is an expert in writing fantastic characters that get under your skin and there are an abundance of them in this book. Forensic Psychologist Dr Connie Woolwine returns for a third time. And though she plays a crucial role, she’s a peripheral character who appears quite briefly. Our main protagonist is Midnight Jones, a brilliant character who not only has a great name but is likeable, brave, tenacious and easy to root for. She has a compelling backstory that made me furious on her behalf but I admired her selfless commitment to caring for her twin sister, Dawn. I loved the sisters’ relationship and many of their scenes together were incredibly moving. There is also a cast of fantastic background characters, with Dawn and septuagenarian Doris - a lifeline for Midnight and all-round lovely person- being my favourites. And then, there’s Profile K. This character is one of the most disturbed, savage, cruel, and remorseless killers I’ve ever read. Just thinking about him gives me chills and I was glad he didn’t narrate the murders, as the peek inside his twisted mind we got when he was contemplating or reliving them was bad enough, though his backstory did help us understand how he became this way. Menacing, macabre, unnerving and compulsive, this is a must read for anyone who enjoys dark and twisted thrillers. Just make sure you’ve nothing planned when you start reading.

With more than a tinge of computer analytics and greedy corporate executives running amok, this latest suspense thriller from Helen Sarah Fields is super gripping, creepy and mesmerizing. I loved the main female character Midnight Jones who, despite her precarious financial situation and her need to care for a special needs twin sister Dawn, keeps plugging away to do the right thing and stop a cold killer, even at the risk of her own life. Like every other novel I've read by this author, the suspense kept me on edge and fascinated, beginning to the high energy action ending. I can't wait to see what Fields comes up with next. Thanks to Harper 360 and NetGalley for sharing a complimentary advance copy of the book; this is my voluntary and honest opinion.

More breath taking than I thought possible! It’s definitely full of momentum,twists and turns, whilst packed with impending horror! Midnight works within a large company that is unbeknown to her is not as truthful as they make out to be.

Midnight Jones analyses data for organisations as part of their employment process. When Midnight comes across a disturbing set of data hinting at sociopathic or psychopathic tendencies her employer tries to persuade her that it's just a glitch in the system. A brutal murder nearby convinces Midnight that the data and the murderer are linked. It becomes a cat-and-mouse race as Midnight tries to identify the murderer before he tracks her down. The opening chapter of Profile K by Helen Fields is dark and disturbing, it sets the tone for this chilling thriller that has a dystopian element. I became a fan of the author back in 2022 when I read One For Sorrow, book 7 in the Luc Callanach and Ava Turner series. While this series features some dark and twisted elements it's the books that feature Dr Connie Woolwine, the psychological profiler, that are the darkest. Woolwine only plays a small part in Profile K but you know that her involvement points to something sinister. At times it almost feels as if you are reading two different books as the story switches between the point of view of the killer and that of Midnight Jones. Seeing into the mind of the killer is chilling. As I was reading my brain was asking me if I'd locked the door and did I have enough lights on. It certainly makes you realise how vulnerable we all are, even in our own homes. We have a less disturbing story when we switch to Midnight's point of view. Midnight is a likeable character. Frustrated by the constraints of her job at Necto but forced to comply as she's reliant on the above-average salary. Midnight has a twin sister, Dawn, who has severe special needs. Their parents have abandoned them to travel the world and Midnight is determined that her sister will not end up in residential care, hence her need for a well-paying job. Necto, the company Midnight works for, is almost as disturbing as the killer. Initially, it sounds as if it is an ideal place to work with its stunning buildings, beautiful environment and enhanced pay. However, working for Necto isn't all fun and games, there are strict policies in place to ensure time isn't wasted and secrets aren't stolen. NDA's and the threat of litigation hang over everyone's head. When Midnight comes across the disturbing profile Necto tries to downplay the data, passing it off as an anomaly and promoting Midnight in an attempt to buy her off. The idea of psychometric testing and it's results raises some interesting questions. Will someone who displays sociopathic or psychopathic tendencies always act on them? Should you incarcerate someone simply because of a psychological profile? A game of cat and mouse ensues, with Midnight and the killer spiraling closer and closer. Everyone comes under suspicion, particularly with Necto playing a "Big Brother" role. You'll find yourself holding your breath as Midnight fights to protect those she loves. And when you're finished, you'll probably double-check you've locked the door.
