Princes in the Tower

The Princes in the Tower was the collective name for the two sons of King Edward IV of England and Elizabeth Woodville who were locked up in the Tower of London prior to the coronation of the elder brother as Edward V of England. The question of what happened to the two princes was a mystery.

The Doctor, then in his third or fourth incarnation, was contracted to solve the mystery by the 64th century publishers of a range of books called Doctor Who Discovers. Due to years of contractual neglect, the job of actually writing the book — tentatively called Doctor Who Discovers: Historical Mysteries — fell to the Fifth Doctor. He in turn took Erimem and Peri back to 1483 to investigate the issue. The trio discovered that in fact there never were princes in the tower, but that Edward and Elisabeth had only had daughters — girls that lived as serving wenches under the names Susan and Judith.

According to another account, the princes Richard and Edward were kidnapped by an agent of the Council of Eight to prevent them from having an impact on history. They were later rescued by the Eighth Doctor and Trix and taken to the 21st century, where they were adopted by Ernest Fleetward. (PROSE: Sometime Never...)
