This is another historical detective set in modern day Egypt. When I started reading it I thought it was one of Will Adams' books. It had a very similar opening as in Adams' "The Alexander cipher" I reviewed few weeks back (in reality, it is likely Adams borrowed book "structure" from Sussman as latter's book was published at earlier date).
Anyone who is into ancient history may know about the army of Persian King Cambyses lost in a desert storm following successful campaign to conquer the ancient Egypt in 6th century BC.
When a fiction novel is about subject known to be inaccessible in reality one can immediately assume that by the time of its ending it should return to status quo. Indeed, this novel describes a rare, once in a life time archeological discovery of the lost Army and in the end the Army is lost again.
The novel is a typical mystery detective story but the ending is actually very surprising and quite unexpecting.
