Kill Them Cold
One lie requires commitment... Multiple lies require dedication...
When the remains of a young woman are discovered near to Branodunum, a Roman archaeological site on the Norfolk coast, DI Tom Janssen and his team must work to discover who she was and how she came to be buried there.
The area is steeped in myth and folklore, a site excavated many times over the years. Just how long has she lain there... and who wishes she'd never been discovered? As the victim’s life comes into sharp focus, it appears there is far more to those who crossed her path than anyone previously realised.
Uncovering dark secrets at every turn, DI Janssen must unravel the web of deceit in order to unmask a killer; possibly the most cold blooded and dangerous murderer he has ever faced.
Set within the mysterious beauty of coastal Norfolk, this fast-paced British detective novel is a dark murder mystery that will keep you guessing until the very end when the final shocking twist is revealed.
Kill Them Cold is the seventh novel in the Hidden Norfolk series of thrillers from the million selling British crime writer, JM Dalgliesh, the author of the Dark Yorkshire books. Perfect for fans of LJ Ross, JD Kirk, Angela Marsons, Joy Ellis and Damien Boyd.

J M Dalgliesh
Before he ever penned a crime scene or built the quiet tension of a small-town mystery, J.M. Dalgliesh was drawn to the shadows that linger at the edges of everyday life—the things left unsaid, the truths that hide beneath the surface. Raised in Norfolk, England, his early years were spent surrounded by the kind of windswept coastlines and weather-beaten streets that would later seep into the moody, atmospheric settings of his novels.
Dalgliesh didn’t follow the traditional literary path. His journey into writing came after years of working with people from all walks of life, experiences that gave him a sharp eye for the unspoken complexities of human nature. That empathy, coupled with a natural instinct for suspense, forms the backbone of his storytelling. His books often explore the fractures beneath seemingly tranquil communities, peeling back layers of civility to reveal the quiet violence that can lurk within.
Hidden Norfolk
Tucked away on England’s brooding east coast, where the land bleeds into mist and marsh, the Hidden Norfolk series unfolds with quiet intensity. It’s here—beneath the surface of a place known more for coastal charm than crime—that the past lingers like fog and truth is a slippery, shifting thing.
Following Detective Inspector Tom Janssen, each story peels back the veneer of village life, revealing the tension, trauma, and long-buried secrets that ripple just beneath. These aren’t crimes of convenience—they’re rooted deep in character, shaped by community and carried out in silence. In this world, justice isn’t clean-cut, and resolution rarely comes without personal cost.
Hidden Norfolk consists of sixteen books and series is set to expand with the upcoming release of one more book. The current recommended reading order for the series is provided below.
