Gaither Stewart’s The Trojan Spy [Punto Press, 2012] takes the thriller genre an important step forward, advancing it from the work of his predecessors John le Carré and Robert Ludlum. Le Carré and Ludlum rebelled against the conventions of the classic spy thrillers, which assumed that we’re the good guys who are under attack by bad guys so evil that we’re justified in bending the rules to save ourselves from them. In that world, lies, deceit, sabotage, and even murder are sometimes necessary to defend peace, justice, and the American (or Western) Way against (pick one, depending on when the book was written) Nazis, communists, or terrorists.
