After enduring the CIA's harshest interrogation methods and spending more than a year in the agency's secret prisons, Khalid Sheik Mohammed stood before U.S. intelligence officers in a makeshift lecture hall, leading what they called "terrorist tutorials."

In 2005 and 2006, the bearded, pudgy man who calls himself the mastermind of the Sept. 11, 2001, attacks discussed a wide variety of subjects, including Greek philosophy and al-Qaeda dogma. In one instance, he scolded a listener for poor note-taking and his inability to recall details of an earlier lecture.

Speaking in English, Mohammed "seemed to relish the opportunity, sometimes for hours on end, to discuss the inner workings of al-Qaeda and the group's plans, ideology and operatives," said one of two sources who described the sessions, speaking on the condition of anonymity because much information about detainee confinement remains classified. "He'd even use a chalkboard at times."

These scenes provide previously unpublicized details about the transformation of the man known to U.S. officials as KSM from an avowed and truculent enemy of the United States into what the CIA called its "preeminent source" on al-Qaeda. This reversal occurred after Mohammed was subjected to simulated drowning and prolonged sleep deprivation, among other harsh interrogation techniques.
