The Amateur — Robert Littell

A spy thriller classic from the author of "The Company"
Before Robert Littell vaulted onto the bestseller lists with "The Company, The Amateur," which has been long out of print, established him as a contemporary master of the espionage thriller. In this sleek and murderous novel, Charlie Heller is an ace cryptographer for the CIA, a quiet man in a quiet back-office job. But when his fiancee is murdered by terrorists and the Agency decides not to pursue her killers, Heller takes matters into his own hands. The fact that he is an amateur makes him all the more dangerous. Mind-blowing in its intelligence, pulse-pounding in its suspense, "The Amateur" is a stunner."
