Roger the Chapman series #17 In the summer of 1482, an English army, under the command of Richard, Duke of Gloucester, invades Scotland in order to win back the border town of Berwick-on-Tweed and to put King James the Third's renegade younger brother, the Duke of Albany, on the Scottish throne. Albany insists that his old acquaintance, Roger Chapman, be a member of his personal bodyguard, so an extremely reluctant Roger finds himself, by royal decree, a part of the invading forces. But during the march northwards, a series of sinister events, centred around the cult figure of the mythical Green Man, makes Roger question Albany's true motive for requesting his presence. And once in Edinburgh, he is not only called upon to solve a murder, but also begins to realize that his own life could be in danger.
