Narrated by Patrick FitzSymons, A Heart of Darkness is a gripping, high-stakes British crime thriller set in Oxford. Dark, urgent, and unflinching, it is the explosive final instalment in the DI Joseph Stone series.

For decades, the peaceful village of Windridge has harboured dark mysteries, whispers of ancient rituals, and hidden crimes.

What begins as a playful ritual quickly spirals into something far darker. When a Nerf gun ‘hit’ connected to an underground Assassins gaming club leads to a real death, DI Joseph Stone is drawn into a world where the rules are dangerously blurred.

Jimmy Harper was a successful vintage car dealer with a passion for perfection. When he is found burned alive inside his prized Aston Martin DB5, it’s clear this was no accident—and no ordinary act of violence.

For sixteen years, the Midwinter Butcher has stalked the edges of Oxford—leaving behind ritualistic animal killings on the anniversary of DI Joseph Stone’s greatest loss. A reminder. A warning. And a case that has consumed him.
