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.

Hidden Norfolk

The series

Full series details →

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.

Read full series description

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.

What makes the series stand out in the realm of British detective fiction is its devotion to atmosphere over action. The sense of place is almost a character in itself—windswept beaches, fading skies, and forgotten lanes form the backdrop to crimes that echo long after the final page. The pacing is deliberate, the storytelling intimate, and the emotional weight unflinching.

Fans of slow-burn crime novels, rich in psychological complexity and steeped in setting, will find themselves drawn into the quiet power of these investigations. There’s nothing flashy here—just sharp writing, layered plots, and a protagonist whose quiet persistence mirrors the landscape he patrols. In Hidden Norfolk, every whisper of wind might be carrying a secret, and no one is ever quite as innocent as they seem.
