In 1943, The United Kingdom is alive with men and women making ready for the greatest invasion in history: preparing to assault Hitler's Fortress Europe. The skies are full of training aircraft, their engines merging with the throb of the RAF and USAAF bombers heading on round-the-clock missions against Germany. With fresh bloodshed on the horizon, the coming Christmas preparations seem even more poignant. But with just ten days to go, the seasonal mood is shattered in the quiet market town of Wantage in Berkshire by the discovery of two badly battered bodies. It seems that the victims were tortured before being beaten to death. Detective Chief Superintendent Tommy Livermore and DS Suzie Mountford, Tommy's right-hand woman and secret lover, are assigned to the case.
