The Peach can be very sly, or thinks he is.  He’s at the top of his powers of beauty and persuasion, and those can be very intoxicating.

He’s not so full of himself as he gets older and the war gets more personal, but that applies to everybody.

The Brit’s not really insulted that he’s been followed.  If he reports this enemy in his own camp, he won’t get to talk to him any more.  All soldiers will sit down and talk to the enemy, because they’ve been to the same battles, and they have more and different viewpoints about something they — and nobody else — can share.

There’s a silent moment in a Miss Marple (McEwen version) episode — probably not in the book — where two Englishmen and a German are sitting at a table after the war, drinking beer and intently talking and laughing over what they share about their battlefields.  The British film that moment a lot.
