Thornwyn

Commander Neville Thornwyn was DS Robert McGraw's boss when McGraw was first promoted to the rank of detective constable in the CID. He was also McGraw's personal hero. It's difficult to reconcile that with Thornwyn's conviction for bribery and corruption, and things are about to get worse. McGraw, investigating a junior minister's suicide, finds there was more to Thornwyn than he ever knew, and what he learns is not only damaging; it also has national security implications.
