London, 2006

DCI John Kennedy is weeks away from retirement when the 1983 disappearance of a young nurse, Kathy Bird, is reignited by a high-profile cold-case feature on Crimewatch—unearthing a new witness and pulling Kennedy into the hunt for a killer who has evaded justice for far too long.

But this isn’t just any predator. Cunning, methodical, and relentless, he has spent a lifetime perfecting his crimes. His web stretches back to the Summer of Love, 1967, where the first pieces of this nightmare were set in motion.

As Kennedy digs deeper, the past collides with the present. Bruce, haunted by the fragmented memories of a crime he witnessed as a child, begins to unravel long-buried truths. Vera, burdened with a terrifying gift of foresight, knows more than she can admit and Stella, raised in the shadow of loss, is determined to uncover the fate of the sister she never met. But the answers come at a price.

With crime, mystery, and a chilling twist of the paranormal, The Sister Redux is an atmospheric, high-stakes thriller that will keep you second-guessing until the final page.

The clock is ticking. The killer is watching. And this time, he’s closer than ever.

Perfect for fans of True Detective, Broadchurch, and The Silence of the Lambs.

Originally released as The Sister, this newly revised edition strips the story down to its raw, adrenaline-fueled core—a pure serial killer thriller with an edge of paranormal suspense.
