I'll be posting my favorites on Facebook and here too for seven days. Here's favorite #1--A Perfect Spy, by John le Carré. A Perfect Spy is really a perfect book; a masterpiece of psychological insight into the life of double agent Magnus Pym, whose father was a con man and a huge influence on his life. I won't give the story away; I will just say that you won't want to put it down.
And after you read the book, I recommend the BBC TV series of the same name that was first broadcast in 1987: http://www.imdb.com/title/tt0092425/?ref_=fn_al_tt_1
