Silverview, by John le Carre

Published posthumously, Silverview is a fitting bow not just to the career of one of the greatest spy novelists ever--but to that of a great novelist, period. In his last work of fiction le Carre continues to ask the questions that fueled earlier masterpieces like The Spy Who Came in from the Cold, but here his interrogation shows his deepest reflections on the moral turpitude of espionage and how it has been complicit in, or even the cause of, many of the world's evils.
