A brutal double murder. A traumatised little boy. Detective Jack MacIntosh tackles his most impossible case yet.

Detective Jack is standing at the graveside of his old friend and mentor, DCI Frank Tyler, when the call comes in. ‘Boss – we need you NOW!’

He arrives at a smart Richmond townhouse to a scene of unspeakable horror. There’s blood everywhere – soaking through the thick-pile rug, slashed across the curtains, sprayed across the ceiling. Two bodies lie side-by-side, next to the king-sized bed. They’re not fresh. They’ve been there at least two weeks.

Nothing adds up. A frenzied attack, yet meticulously executed. Carefully planned. No forced entry.

Then the most chilling discovery of all.

A six-year-old boy, hiding in the study. Clothes stiff with dried blood. Eyes blank. Silent.

Joshua is the only witness. And whatever he saw has trapped him deep inside himself.

Now Jack is in a race against time to unlock the little boy’s memories and coax out the truth - before the killer returns to silence Joshua for good.

Perfect for fans of Helen H. Durrant, Biba Pearce, Lynda La Plante, Angela Marsons and Rachel McLean.
