I am a great fan of Robert Harris's fiction but this was my first of his nonfiction books and it did not disappoint. The book tells the incredible story of how a rather  lazy and greedy journalist at a German magazine in the 1980s is convinced that Hitler had written a series of personal diaries and that these had been recovered from a plane crash and were being smuggled out of east Germany. His magazine hands over millions of marks for the purchase of the diaries with plans to publish them in a series of articles. The story of greed and ineptitude unfolds very slowly (at time agonizingly) to the eventual testing of the material by real experts in Hitler's writing and forensic testing of the materials. 
I must say it took me a long time to read this book with many intervals, but I am glad I read it.

There are quotes on the book's cover saying 'Impossible to stop reading' and 'utterly fascinating'
They are both absolutely right, I could not put this book down, Harris expertly displays the main players and the narrative. All this without showing a bias one way or another, except like the reader, an incredulity that it happened in the first place.

Highly recommend, an excellent example of gripping Non-fiction

Audiobook. It felt very low stakes to me while being high intensity, drama, and risk to all the misguided men involved. This is frankly the ideal.
