As a physician in London during the Wars of the Roses, Dr Luke Chichele became well acquainted with royalty and was part of a plot instigated by the Pope to find out exactly how King Henry VI died in 1471 in the Tower of London. Was it suicide or murder? The Pope wanted to prove Henry VI was worthy of beatification, while the King, Edward IV, claimed he had died witless and incapable. But the closer Luke came to the truth, the more his life fell into danger.
