The Mathematics of Magic (L. Sprague De Camp) (L. Sprague De Camp)

Harold Shea is a psychologist who dreams of adventure, but never gets beyond learning to fence and occasionally showing up at staff meetings dressed in horseback riding garb. But when he learns that his boss, Dr. Reed Chalmers, has developed a theory which allows a person to transport himself to any world he can imagine, Harold Shea decides to give it a whirl. This volume includes all the De Camp and Pratt Enchanter stories.
