"Drawing on interviews with active and former British, American, Russian, European, and Asian intelligence officers and agents, . . . creates a layered portrait of why spies spy, what motivates them, and what makes them effective. Love, sex, money, patriotism, risk, adventure, revenge, compulsion, doing the right thing--focusing on the motivations, [this book] presents a wealth of spy stories, some previously unknown and some famous, from the very human angle of the agents themselves.
