From the Daily Mail:
To her neighbours in the nearby Rue Verdun, Penelope was just another eccentric foreigner living her life as best she could in the heart of war-torn west Beirut.
What has, however, become apparent is that far from being an innocent Englishwoman abroad, Penelope was a Mossad spy trained to use her feminine wiles to inveigle her way into the life of one of the world's most feared terrorists - and then help kill him.
Evidence that has emerged over the years suggests that she was in fact a British woman by the name of Erika Maria Chambers, and she was born and brought up in London as part of a wealthy Anglo-Jewish family.
But there is one further, extraordinary, twist to the story. Erika Maria Chambers, 'Mossad assassin', has a brother. His name is Nicholas Chambers - and he is a QC and leading civil court judge who is a pillar of the British judicial establishment.
