THE BEASTS OF VALHALLA. Hardcover – January 1, 1985 by George C. Chesbro
Book 4 of 14: The Mongo Mysteries
 
A detective takes on mad scientists when a D&D fantasy world turns deadly in this “ thrilling combination” of “not-quite-science-fiction and suspense” (Playboy).
 
With a genius IQ, a past career as a circus acrobat, and a black belt in karate, criminology professor Dr. Robert Frederickson—better known as “Mongo the Magnificent”—has a decidedly unusual background for a private investigator. He also just so happens to be a dwarf.
