"Unfortunately, we only have one Ali Soufan. Had American intelligence listened to him, 9/11 might never have happened. No one did more to unravel the story of al-Qaeda than Ali Soufan. Thankfully, he's left another legacy in this book. Anyone who wants to know what really happened should read it. It's an inspiring but wrenching story told from the heart of a great American." -- Lawrence Wright, author of The Looming Tower: Al-Qaeda and the Road to 9/11.

It is 7pm on a Friday and more than 200 people are queuing for a chance to buy an iPad at 30 per cent off. Those who succeed immediately rip open the box to admire the results of their hard work.

"You can't stop the mujahideen," Abu Jandal told me on September 17, 2001. "We will be victorious." We sat across a rectangular table from each other in a nondescript interrogation room with unadorned white walls in a high-level national security prison in Sanaa, the capital of Yemen.

A former FBI agent who worked at the heart of America's battle against al-Qaeda has told the BBC he is being prevented from telling the truth as he challenges the back story of 9/11 and what has happened since. Mr Soufan also argues against the effectiveness of interrogation techniques used by the CIA, such as water boarding.

As an Arabic-speaking FBI agent, Soufan was at the center of several Al Qaeda investigations before and after 9/11.
