CORNWALL, 1967. Two children witness a brutal act—one a seven-year-old boy watching from the clifftops, the other a girl glimpsing it from her bedroom in Ireland. Neither speaks. Both are changed.

LONDON, 2006. Nearing retirement, DCI John Kennedy is still haunted by one case he never cracked: the disappearance of young nurse Kathy. A national Crimewatch reenactment retraces her last steps and jolts the case alive. A new witness emerges. The trail points not to a lone tragedy, but to a patient predator.

As Kennedy follows the leads, he’s drawn into a deadly cat-and-mouse that spans decades and coastlines. The adversary he hunts is no ordinary killer, and only the long-silent witnesses from that summer of ’67—who have never met—can help expose the truth.

Blending police procedural, psychological suspense, and a chilling supernatural undertow, The Sister twists time and memory into a taut, propulsive mystery. For readers who love cold-case puzzles, British detectives, and stories where the past refuses to stay buried, this is a haunting thriller that keeps you guessing to the final page.

Gripping, atmospheric, and deeply psychological, The Life and Times of William Boule is a taut thriller that dives into the murky depths of obsession, justice, and the collateral damage left in their wake. Perfect for fans of The Girl with the Dragon Tattoo and The Silent Patient, this is a journey Miller and Carla won’t forget—and one they may not survive.
