The crackling new novel in the bestselling Honor Bound series, by the master of the military thriller.     As with his other enormously popular series, the first two novels in W. E .B. Griffin&;s saga of World War II espionage in Germany and Argentina &; Honor Bound and Blood and Honor &; became immediate bestsellers and were hailed as &;immensely entertaining adventures&; (Kirkus Reviews). Now, in Secret Honor, Griffin creates his most rousing novel yet.     In Wolf&;s Lair, a German general works toward the assassination of Adolf Hitler. In Buenos Aires, the general&;s son, code-named Galahad, falls under suspicion by the SS after a Nazi operation suddenly goes bad. In the middle of it all is OSS agent Cletus Frade, who knows the identity of father and son and what they will do next&;if they can survive that long. For not only are SS and Abwehr officers hot on their trails in both countries, but the OSS has branded Frade a rogue agent and is determined to shake the truth from him, at whatever cost. If Frade can&;t figure a way to hold them all off, then the futures of all three men may be very short indeed&;.     Written with the special flair that Griffin&;s readers expect, filled with high drama and real heroes, Secret Honor is further proof, in Tom Clancy&;s words, that &;Griffin is a storyteller in the grand tradition.&;
