Simplistic and straightforward, especially compared to [b:The Secret Pilgrim|46462|The Secret Pilgrim (George Smiley, #8)|John le Carré|https://d202m5krfqbpi5.cloudfront.net/books/1170330461s/46462.jpg|876061], which is the only other John le Carré book I've read.
It's espionage mixed with a murder investigation a la Agatha Christie. I thoroughly enjoyed it.
