Call for the Dead, John Le Carre

Finished listening to Call for the Dead. This is the first Le Carre novel, and for a first one, it’s written pretty well. It was obviously influenced by Julius and Ethel Rosenberg couple.
Listening to it after “The Spy Who Came in from the Cold” is interesting, because you can see how Mundt was retrofitted to be a double agent later on. There’s very little wiggle room for that in the original novel.
Also interesting that Dieter, Smiley’s pupil that switched to work for East Germany after the war, is confirmed dead by the end of the novel. I’d thought author would leave it hanging.
