Vividly portraying legendary and semi-legendary figures such as Lear, Cymbeline, Merlin the magician and the most famous of all British heroes, King Arthur, it is as much myth as it is history and its veracity was questioned by other medieval writers.

    She rode out at the head of an army in both victory and defeat; saw her second husband assassinated, and married his murderer. At twenty-five she entered captivity at the hands of her rival queen, from which only death would release her.The life of Mary Stuart is one of unparalleled drama and conflict. From the labyrinthine plots laid by the Scottish lords to wrest power for themselves, to the efforts made by Elizabeth's ministers to invalidate Mary's legitimate claim to the English throne, John Guy returns to the archives to explode the myths and correct the inaccuracies that surround this most fascinating monarch. He also explains a central mystery: why Mary would have consented to marry – only three months after the death of her second husband, Lord Darnley – the man who was said to be his killer, the Earl of Bothwell. And, more astonishingly, he solves, through careful re-examination of the Casket Letters, the secret behind Darnley's spectacular assassination at Kirk o'Field. With great pathos, Guy illuminates how the imprisoned Mary's despair led to a reckless plot against Elizabeth – and thus to her own execution.The portrait that emerges is not of a political pawn or a manipulative siren, but of a shrewd and charismatic young ruler who relished power and, for a time, managed to hold together a fatally unstable country.
