Dr. Robert "Mongo" Fredrickson, a.k.a. Mongo the Magnificent, is a fictional private eye and criminologist who has dwarfism, appearing in several books by George C. Chesbro. His rather unusual nickname is actually his stage name, from his days as an acrobat in a circus (a career that is over by the time the book series begins).The novels are usually classified as mysteries, but frequently contain strong elements of speculative fiction such as extra-sensory perception and cryptozoology.
