Inside the tower of London two young boys, initially held in great splendour, are being seen less and less. History knows them as the princes in the tower, and their disappearance is one of, if not the greatest royal mystery in Great Britain's long and dramatic history. Although few doubt that they met their end in the Tower of London, more recently there has been a re-examination, with some believing the boys not only escaped the confines of the dreaded fortress, but lived on, to later attempt to win back the throne that should have been theirs. But what new evidence was put forward, what is the back story behind these two princes, and why is their story likely to remain unsolved?
