Beneath a country road, an abandoned quarry track hides a decade-old secret. The discovery of human remains plunges DCI Beniamin Dinescu into a mystery driven by jealousy, obsession, and long-buried lies.

In a derelict house, another dark mystery surfaces, revealing a crime far more complex than they imagined. Two discoveries. One question: how are they connected? To uncover the truth, they must navigate a fractured family’s past, where love and betrayal can both be motives for murder.

Some secrets should stay buried...

Dinescu, Summers, and the team return in a gripping mystery set against the evocative backdrop of Chichester and its surrounding villages. One Dark Thought is a British police procedural that will keep you hooked until the very end.
