A bit slow getting under way, but once started it is good reading and a vigorous picture of the havoc wrought by the Wars of the Roses, interweaving of international strings, treachery, conflict between nobles and kings. Historical interpretation rather than historical fiction. A sympathetic picture of Richard III showing him betrayed by his loyalty to Edward IV -- the victim of forces beyond his control, even to his implication in the death of the Princes in the Tower. Interesting material, detailed in handling, and dealing with a period which is confusing to many readers.
