Published in the 12/1936 issue of Secret Agent X.
"Secret Agent X knew that the destiny of millions of honest people rested in his judgment of a beautiful but crafty woman. And all the Agent’s plans fell to pieces when his most important confederate, Harvey Bates, rebelled against orders. For Bates insisted that Charlotte, the glamorous and powerful spy of old, was incapable of any evil."
