The mystery of Dr Aafia Siddiqui

The prosecution is but the latest twist in one of the most intriguing episodes of America's "war on terror". At its heart is the MIT-educated Siddiqui, once declared the world's most wanted woman. In 2003 she mysteriously vanished for five years, during which time she was variously dubbed the "Mata Hari of al-Qaida" or the "Grey Lady of Bagram", an iconic victim of American brutality.
