Shadows of Heroes Author: D. M. Ulmer; Editorial Assistant: Doris Littlefield; Managing Editor: Dari Bradley; Executive Editor: Nelson O. Ottenhausen. January 1949, early in the undeclared Cold War, the U.S. diesel-electric submarine Kokanee has illegally penetrated deep into Soviet Union waters of the White Sea and is detected by a pair of Russian destroyers. Depth charges fall on Kokanee and seem on the verge of tearing the besieged ship apart. A vindictive Russian captain is determined to eradicate the Americans. Two U.S. intelligence agents have been put ashore, their mission: determine whether the Soviets are developing a nuclear powered submarine. Commander Terry Martin violated Kokanee's patrol orders and risks everything, including his career, against the long odds of acquiring information essential to the long term security of the United States.
