I remember seeing a book on a desk somewhere. I have the feeling it was about WW2 or something related. It was a thick black book (or part of the cover was black) with bold white lettering. I'm sorry that isn't much to go on.
The Rise and Fall of the Third Reich perhaps? That's really the best guess I can come up with given such little info.
