(The third story, Envoy Extraordinary, was first published in a collection in 1956. The other two are presented here for the first time.)
About the book (from Goodreads):
Three short novels show Golding at his subtle, ironic, mysterious best. The Scorpion God depicts a challenge to primal authority as the god-ruler of an ancient civilization lingers near death. Clonk Clonk is a graphic account of a crippled youth’s triumph over his tormentors in a primitive matriarchal society. Envoy Extraordinary is a tale of Imperial Rome where the emperor loves his illegitimate son more than his own arrogant, loutish heir.
