Lord John and the privat matter

The year is 1757. On a bright Jun day, Lord John Grey emerges from his club, his mind in turmoil. A nobleman and a high-ranking officer in His Majesty's Army, Grey has just witnessed something shocking. But his efforts to avoid a scandal that might destroy his family are interrupted by something still more urgent: the Crown appoints him to investigate the brutal murder of comrade-in-arms, who might well have been a traitor.
