In Historic Doubts of the Life and Reign of King Richard III, Walpole defends Richard III against the common belief that he murdered the Princes in the Tower, and many of the other crimes laid at his door by the Tudor dynasty which followed Richard’s defeat at the Battle of Bosworth in 1485. In this he has been followed by a number of other writers, including Josephine Tey in her classic 1951 mystery novel The Daughter of Time.
