A smart pace for the events -- lethal in intent -- aboard the cross country train carrying Governor Martin, a presidential candidate, his two children, secretaries, newspapermen, guards and political advisers. The Governor is shot at; his second secretary is ready to join the killer if she can discover him; each stop is a threat and there are professional and personal clashes as they head east, until the secretary plays ball with the would be killer and emerges a heroine. Good hunting.
