Philippa Langley challenges the traditional narrative surrounding Richard III's alleged murder of the Princes in the Tower, arguing that there is insufficient evidence to support this claim. Her book, "The Princes in the Tower," takes a true-crime approach to the mystery and questions whether Richard III was a murderer or a victim of historical rumor and prejudice. Langley's research is based on archival evidence and argues that the boys were alive when Richard was crowned, suggesting they were later given false identities by the Tudor government.
