Query: Highly Believable

The level of investigative effort Asher puts into this book is extreme. And yes, he seems the perfect character to uncover the truth too, being experienced in both the SAS and in Arabic culture, first hand. The book impresses the reader with an honesty missing from McNab's and Ryan's books, without condemning them for wanting to make a truckload of money from their stories.
