The loophole

Laurel Bowman and Frank Diamond, partners in The Anglian Detective Agency, go undercover at Sam Salter's holiday camp, near Orford, Suffolk. Their mission: to discover what happened to two missing members of staff. Thomas Coltman, a camp worker and isolate, is the agency's main suspect. His wife and young son were murdered during WW2 when he was a prisoner of war in Java. Is he taking a twisted revenge? There are brutal murders in Orford. Are they connected to their case? Does Orfordness, a forbidden spit of land, with pagoda-shaped buildings, used to test nuclear bombs after WW2, hold the key to the mystery?
