William Shakespeare's Scottish story of witchcraft and murder is probably one of his darkest works. Retold for students of English at English Language Teaching (ELT/ESL) upper intermediate level, this Macmillan Reader eBook is written as a play script and includes original extracts. Macbeth's bloody rise to power is encouraged by his wife, Lady Macbeth. Like her husband, Lady Macbeth's ambition leads her into a dark world of guilt and madness which slowly destroys their marriage, and ends in tragedy.
