Hard to say how this was an insiders story. The author having only worked for NR for less than 3 years, can hardly know the ins and outs of the company. Quite a large portion of the book is dedicated to his own self promotion, in his role. Similarly, being only middle management, did not have access to management information about the crisis. Much of the information presented, was at best anectodal from news reports or simply taken from publications in the public domain, such as treasury select committee minutes and FSA publications. Likewise the author can't really give a full story, there is still much more to tell. His story ends, when the real story begun. A rat jumping a sinking ship and simply wanting to 'cash in'.
