Johnstone learned from the master, Uncle William W. Johnstone.     He began tutoring J.A. at an early age. After-school hours were often spent retyping manuscripts or researching his massive American Western History library as well as the more modern wars and conflicts. J.A. worked hard—and learned.    “Every day with Bill was an adventure story in itself. Bill taught me all he could about the art of storytelling. ‘Keep the historical facts accurate,’ he would say. ‘Remember the readers, and as your grandfather once told me, I am telling you now: be the best J.A. Johnstone you can be.”
