John le Carré's classic novels deftly navigate readers through the intricate shadow worlds of international espionage with unsurpassed skill and knowledge. A Perfect Spy is one of his richest and most morally resonant novels.

Magnus Pym - son of Rick, father of Tom, and a successful career officer of British Intelligence - has vanished, to the dismay of his friends, enemies, and wife. Who is he? Who was he? Who owns him? Who trained him? Secrets of state are at risk. As the truth about Pym gradually emerges, the reader joins Pym's pursuers to explore the unsettling life and motives of a man who fought the wars he inherited with the only weapons he knew, and so became a perfect spy.
