Fire Eye - the Story of a Boy and a Horse
Albert Whitman & Company, Chicago, 1948, 32 pp, illus the author
When his family moves to the city, Bob has to part with the filly he raised from a foal. He is reassured to learn that the new owner plans to train her as a show horse, and she will receive the greatest of care. Bob adjusts to the city, but never forgets Fire Eye. Two years later, Bob is walking with a friend, and sees a thin, tired horse pulling a wagon. He is stunned to see it is Fire Eye, and is determined to find out how she got there, and equally determined to get her out of there.
