The main issue that Nine Lives has to overcome is the one that has attended Aimen Dean (a pseudonym) since he went public in March 2015 with an interview he gave to the BBC, claiming he had been a British spy within Al-Qaeda between 1998 and 2006. That issue is overcoming the doubts about his story. Nine Lives goes a long way to solving this by bringing in Paul Cruickshank, the editor-in-chief of CTC Sentinel, one of the premier academic resources in the terrorism field, and Tim Lister, a terrorism-focused journalist with CNN, as co-authors. As well as helping structure the book from Dean’s memories, the two co-authors note they had been able to “corroborate key details” that convinced them: “In the years immediately leading up to and following 9/11, Aimen Dean was by far the most important spy the West had inside al-Qaeda”.
