I've started on a bit of a le Carre project - after enjoying the film of Tinker Tailor Soldier Spy I read the book and then watched the Alec Guinness tv series, and now have also worked my way through both The Spy Who Came In From The Cold and The Honourable Schoolboy. I think that Smiley's People is next on my list (then there's more excellent Alec Guinness I can watch!), but after that what do le Carre fans advise? I understand that TTSS, THS and SP are the "Karla Triology" but are there any others with Smiley, Guilliam et al in that follow or proceed those books? And are there any others that are connected in themselves and should be read in a particular order?
All advice most gratefully received. Thanks!
