The future of the princes in the Tower is in Richard's hands: they are a threat to his reign but also to Margaret's hopes of seeing her son Henry Tudor on the throne. As Margaret plots the boys' removal, Anne is tormented by fears she has unwittingly sealed the princes' fate. Elizabeth, in sanctuary, is horrified to realise she has made a pact with her enemies and turns to witchcraft to punish the guilty.
