This is the account of the heroic deeds of Margery Booth, a mezzo-soprano from Wigan, Lancashire who married a powerful German industrialist Herr Strohm. She captured the hearts of all who heard her sing, including Adolph Hitler, who was so taken with her that she was invited to join him, at his famous stronghold, the Eagle's Nest.
Her ability to move freely within the higher echelons of Germany's leaders, made her an obvious candidate for recruitment by MI6, British secret services, and in the years leading up to the war she managed to obtain a vast amount of important information. She continued to work for MI6 throughout the war, and after one infamous incident, became affectionally known by her controllers as 'The Knicker Spy'.
In the period following the war she was instrumental in the convictions of Lord Haw-Haw and John Amery, yet her heroic spying exploits were never acknowledged by her country, nor was she to recieve any medals for her services. This is the story of her time in the employ of MI6, including the tale of how she got her infamous nickname.
