The Sorcerer's Letterbox and the Mystery of the Princes in the Tower - Part Three

The entire episode of the Princes in the Tower is still shrouded in mystery. The Duke of Gloucester had Edward V and his younger brother, Richard, Duke of York, imprisoned in the Tower of London, declared them illegitimate and named himself rightful heir to the crown, becoming King Richard III. 

Edward and his brother were occasionally glimpsed in the grounds of the Tower in the summer months, but after the beginning of September they were never seen again. The two young boys were apparently murdered by, or at least on the orders of, their Uncle Richard, although there are a number of competing claims as to who exactly might have been responsible for their demise.
