Printed in Super-Mystery Comics V1 #5, December 1940, with 10 color pages.
Arnold Rire, foreign spy, has stolen charts of U.S. Fortifications. Q-13 has been assigned to catch Rire before he can get out of the country with the charts. (Oddly, a telegram he receives right away has him following Rire to Tajan, Mexico, which is already out of the country.)
