Rose of the Yukon1949

Major Geoffrey Barnett, U. S. Army Intelligence Service, is sent to Alaska, to apprehend a deserter, Tom Clark, who was presumed to be dead as a member of a small force wiped out on Attu in World War II. With the aid of Rose Flambeau, he finds evidence that the now-prosperous Clark killed his own comrades to prevent their reporting of a deposit of uranium, which he is now mining with the intention of selling to a foreign power.
