Dr. De Soto, a mouse dentist, and his assistant, Mrs. De Soto, make a nearly fatal error in judgment when they agree to accept an ailing fox as a new patient. Bright full color illustrations fully integrated with the text add humor to a remarkably well-written, imaginative story in which the De Sotos out fox the fox. Outstanding in concept and development.
