Full and detailed views of the cover of the 1990 Harper Paperbacks edition of The Fly on the Wall. Design credit: Cover design and illustration by Peter Thorpe, Hillerman's long-time graphic collaborator. Notice the design elements Thorpe carries over from what he is best known for, cover design and illustrations for Hillerman's Navajo Detective series: framing devices on the back cover, in this case columns and bunting as opposed to his typical use of yei, and a horizontal landscape populated with significant iconography relevant to the novel's plot line.
