The Third part of King Henry the Sixth — Act 5, Scene 6: London. The Tower.

On the walls of the Tower, King Henry sits with a book when Gloucester enters and sends away the lieutenant so they can speak alone. Henry, still grieving the murder of Prince Edward in the previous scene, accuses Gloucester of being a killer of innocents and laments the suffering caused by civil war. Gloucester answers coldly, says he killed the prince for his presumption, and grows angry at Henry’s prophecies against him. When Henry predicts more bloodshed from Gloucester’s birth and nature, Gloucester stabs him and finishes him off. Left alone with the body, Gloucester reflects on his own deformity, rejects brotherly affection, and carries Henry away.
