Book excerpt: It’s been two years since Milo March sneaked into East Germany to capture a valuable Western deserter. Now, as a major in the Army Reserves, he is recalled to tackle a much weirder case. No one knows why Hermann Gruss, head of the counterespionage police in West Germany, disappeared behind the Iron Curtain. Did he defect voluntarily, or was he taken by force? Either way, Milo has to get him back before he reveals secrets that the U.S. shared with him. Some say Gruss suffers from a dread disease and is being treated in East Berlin with the latest wonder drug by his friend Dr. Oderbruch. Milo suspects that Oderbruch, a former Nazi, is experimenting on Gruss, bouncing him in and out of insanity like a yo-yo by dosing him with LSD, then healing his “schizophrenia” with an antidote. Withholding the antidote is a handy way to squeeze information out of Gruss, and the drug experiments are part of a larger, fiendish project involving mind control of the military. In his effort to gain access to Oderbruch and find Gruss, Milo ends up in the arms of the lustful Frau Beate, who plies him with Soviet champagne and vodka. Milo is reasonably safe if hangovers are the only menace. But when his disguise as a Russian secret-police agent is blown, he is packed off to a mental hospital. There he joins Gruss as the doctor’s latest guinea pig. Milo survived a marathon interrogation by the Communists during his last mission. But this is different—the hallucinogenic effects of LSD threaten to splinter his mind into pieces. How will he escape the closely guarded hospital, bringing both Gruss and the evil Oderbruch back with him to the West? Milo’s quick-witted action and sheer nerve, not to mention his irreverence toward authority figures on both sides, make for the wildest trip of all—an insane car chase back to the Free World.
