In Fox Tracks, New York Times best-selling author Rita Mae Brown delivers another exciting episode in her popular foxhunting series. When Master of the Jefferson Hunt ''Sister'' Jane Arnold is confronted with two ominously similar deaths, she begins to suspect that the killings are linked- and part of a much larger plot. Voicing her opinion soon puts Jane's life in danger. Fortunately, she can turn to her four-legged friends- including horses Keepsake and Lafayette, and even the fox Aunt Netty- for help.
