When Belle Boyd, the Rebel Spy, learned of a plot to organize the Southern States in an attempt to secede from the Union, she faced a problem. During the War Between the States, she had rendered loyal service to Dixie. At its end, she had taken the oath of allegiance to the Union and was now a trusted member of the U.S. Secret Service. Any clash of loyalties was averted when the Frenchman, a leader of the Brotherhood for Southron Freedom, caused the deaths of two of Belle's friends. The Rebel Spy swore that she would avenge them...Even if it had to smash the Brotherhood to do it!
