Hilary Mantel's novel 'Bring Up the Bodies' features which queen's execution?

Bring Up the Bodies is a historical novel by Hilary Mantel and sequel to her award-winning Wolf Hall. It is the second part of a planned trilogy charting the rise and fall of Thomas Cromwell, the powerful minister in the court of King Henry VIII. Bring Up the Bodies won the 2012 Man Booker Prize and the 2012 Costa Book of the Year. It is to be followed by The Mirror and the Light.

Bring Up the Bodies begins not long after the conclusion of Wolf Hall. The King and Thomas Cromwell, who is now Master Secretary to the King's Privy Council, are the guests of the Seymour family at their manor house, Wolf Hall. The King shares private moments with Jane Seymour, and begins to fall in love with her. His present queen, Anne Boleyn, has failed to give him a male heir. Their relationship is a stormy one, sometimes loving and sometimes characterized by angry quarrels. At length, the King tells Cromwell privately, "I cannot live as I have." Cromwell understands this to mean that the King has tired of a wife who gives him neither peace nor a son and wants his marriage to her ended. Cromwell promises the King he will find a legal way to make this happen.

Cromwell relishes the task and after accusing Anne of being adulterous. He has several of her confidantes, including her brother, tried and executed.
