The Spy who Billed Me:
Forget the cover story of waterboarding-leads-to-courier-leads-to bin Laden (not to deny the effectiveness of waterboarding, but it’s just not applicable in this case.) Sources in the intelligence community tell me that after years of trying and one bureaucratically insane near-miss in Yemen, the US government killed OBL because a Pakistani intelligence officer came forward to collect the approximately $25 million reward from the State Department's Rewards for Justice program.
The informant was a walk-in.
The ISI officer came forward to claim the substantial reward and to broker US citizenship for his family. My sources tell me that the informant claimed that the Saudis were paying off the Pakistani military and intelligence (ISI) to essentially shelter and keep bin Laden under house arrest in Abbottabad, a city with such a high concentration of military that I'm told there's no equivalent in the US.
read into it what you will; I don't know the veracity of the author:
Dr. Hillhouse has run Cuban rum between East and West Berlin, smuggled jewels from the Soviet Union and slipped through some of the world’s tightest borders. From Uzbekistan to Romania, she's been followed, held at gunpoint and interrogated. Foreign governments and others have pitched her for recruitment as a spy. (They failed.)
A former professor and Fulbright fellow, Dr. Hillhouse earned her Ph.D. in political science at the University of Michigan. Her latest novel, OUTSOURCED (Forge Books) is about the turf wars between the Pentagon and the CIA and the privatization of national security.
