Elizabeth I: Killer Queen (2010)

Here is one of the great mysteries of English history. Elizabeth I is said to have carried on an affair with a leading nobleman, Robert Dudley. Rumors spread that the Queen wanted Dudley's wife, Amy Robsart, dead. Amy turned up savagely murdered. While an inquest cleared the Queen, new evidence today suggests that Amy was indeed assassinated so that her husband could be free to marry the Queen.
