Britain is at war. But some battles are fought in the shadows.

As Hitler's forces storm across Europe, the British government issues the call to arms. But not everyone is sent to the front. Detective Inspector Brakes is deemed too essential to the home front — a bitter pill for a man desperate to fight alongside his countrymen.

Torn between duty and guilt, Brakes must turn his focus to a new kind of enemy: murderers, spies, and saboteurs hiding behind blackout curtains and air raid sirens. Norwich is on edge, and justice has never been murkier.

With bombs falling from above and secrets buried beneath the rubble, DI Brakes is about to uncover crimes as twisted and brutal as any battlefield. His war is here. And it's only just begun.
