内容简介：
In the summer of 1482, an English army, under command of Richard, Duke of Gloucester, invades Scotland. They plan to win back the border town of Berwick-on-Tweed and to put King James Ill's renegade young brother, the Duke of Albany, back on the throne. Roger the Chapman, called upon to be a member of Albany's personal bodyguard, finds himself, by royal decree, a part of the invading forces. But a series of sinister events, centered round the mythical Green Man, makes Roger question Albany's true motive for requesting his presence. Then, once in Edinburgh, he is required to investigate a murder - and begins to realize that his own life could be in danger.
