This is a screen shot taken from the pre-credits sequence of Casino Royale. Dryden, the corrupt Head of Station in Prague, has just entered his office late at night, unaware that Bond is waiting for him. He suddenly realises that he is not alone, although with his back turned towards Bond he doesn't know as yet who is with him. There is a quick cut to his point of view, still facing away from Bond, and this shot is what he sees.
What is it? I have looked and looked at this, but I can't make sense of it--any guesses?
