Dr Marcus Hoag, an American Antique Specialist, had been searching for the lost monastic rule of order for almost thirty five years. When he meets up with his son at his old alma mater and encounters a co-conspirator in his deceased wife's sister and an FBI Agent, he finds himself on the trail of conflicting clues found on the stained glass windows from the Graduation hall and Old Chapel. As he traverses the Atlantic to Canterbury and up through the shires of England, Marcus, with cunning fortitude, will always be one step ahead of his old adversary, the corrupt Dean of the university John Graham, who follows him with dangerous determination.
