Thanks to this subreddit, I'm starting Le Carre

Thanks to stumbling onto this subreddit a few days ago, I've started reading Call for the Dead. I'm really enjoying it so far. I'm planning to read all of the Smiley novels in order and then move from there. I really enjoy the writing style as well as Smiley being much more realistic than many other spy novel/spy movie characters that are just another type of action hero.
