"Tutankhamun: The Untold Story", Thomas Hoving, Simon and Schuster, (1978).

This book came as a shock to the people who thought Howard Carter was the most perfect of archeologists. Here we learn he pilfered objects from the tomb, violated the rules of his concessions, deliberately snubbed people who were trying to help him, and was an all-around pain in the rear end. The biggest revelation was that Howard, Lord Carnarvon, and Lady Evelyn entered the tomb the night they breached the door, rather than wait for the Inspectors of Antiquities like they were supposed to.

Other people (such as T. G. H. James) have questioned some of the revelations in the book. Tom, though, writes a good story and here you learn a lot about the people involved.
