A riddle inside of a mighty book

Covered by work?
Yes indeed, but, always, come hell or high water, making some little time for reading... No matter what, matter of fact, I've unplugged my TV/ DVD player, literally, no temptations whatsoever.

Finished the Beevor one on D-Day; it was really good, certainly I can see why it got all that attention it got, but, for the moment, my favorite on the Europe campaign remains Ambrose "Citizen Soldiers".

The one I'm reading now, Beevor's one on Stalingrad it is, to put it simply, quite an amazing book.
