Dark and violent, Macbeth is also the most theatrically spectacular of Shakespeare's tragedies. Promised a golden future as ruler of Scotland by three sinister witches, Macbeth murders the king to ensure his ambitions come true. But he soon learns the meaning of terror-killing once, he must kill again and again, and the dead return to haunt him. A story of war, witchcraft, and bloodshed, Macbeth also depicts the relationship between husbands and wives, and the risks they are prepared to take to achieve their desires. Macbeth is one of the last of Shakespeare's great tragedies, and is certainly one of his most disturbing. The insights it affords and the aura of evil that pervades it (it even has its own curse), means that "The Scottish Play" stands out luridly even among Shakespeare's blackest tragic brood.
