As Salman Rushdie knows, the pen may be a deadly weapon. His real name is David Cornwell, but as JOHN LE CARRE, this son of the Cold War has plumbed national security anxieties and inner-family conflict again and again, in books that even academics are not ashamed to read on the plane. The newest novel from the best-selling spy novelist, Single & Single, once again recasts the "spy" as the "spy in the family," pitting son against father. Corrupt liaisons, financial whitewashing, the new Russia, and his own past all comprise Le Carrè's complicated and sometimes controversial politics. He makes a rare appearance here to read from his new book.
