ISBN 978 1 85944 041 1. Sir Francis Walsingham is best known as Elizabeth I’s Spymaster General and for the ruthless efficiency with which he carried out that role. Elizabeth did not like him but she valued him and he saw his duty as paramount, however awkward she could be. He was consistently in favour of defending protestants and tracking down catholic conspirators. As Elizabeth’s ambassador Walsingham was in France at the time of the St Bartholomew’s Day Massacre in 1572 and it was that experience which gave him a lasting hatred of the Catholic Church.
