Here's a different kind of spy story, one that takes in a lot of local history and crime, uninvolved but related to the situation. Pug Potter, self-made businessman, is recruited to assist a tough Marine Major in discovering and exposing the enemy agents who are determined to obtain the secret formula for the violent high explosive that is protecting American ships and troops by destroying wolf-pack submarines.
