This is the trade version of the Armchair Detective Library hardcover edition of The Fly on the Wall, published in 1990, with a new introduction by Tony Hillerman.
This is a hardcover book with a dust jacket. The cover design (uncredited) has an overall marbled background in gray, green, yellow and brown, with a few orange highlights. The author's name is printed on a beige inset, in black with light blue drop shadow, above a diamond-framed black and white drawing of Tony Hillerman by Carolyn Hartman.

The back cover has the same marbled background and beige insert, with a brief biography of Tony Hilerman and advance praise for the novel. The publisher logo is at the bottom of the back cover. The front fold-out has a synopsis of the novel, and the back fold-out describes other books in the Armchair Detective Library series. The inside front and inside back cover are blank, and the end papers are white.
