A party at Lily Rowan's Park Avenue penthouse includes a roping contest between some cowboy friends, with a silver-trimmed saddle as the prize.

In his limited-edition pamphlet, Collecting Mystery Fiction #10, Rex Stout's Nero Wolfe Part II, Otto Penzler describes the first edition of Three at Wolfe's Door: "Orange cloth, front cover and spine printed with dark brown. Issued in a mainly green-brown dust wrapper." In April 2006, Firsts: The Book Collector's Magazine estimated that the first edition of Three at Wolfe's Door had a value of between $200 and $350. The estimate is for a copy in very good to fine condition in a like dustjacket. 1960, New York: Viking (Mystery Guild), July 1960, hardcover
The far less valuable Viking book club edition may be distinguished from the first edition in three ways:
 The dust jacket has "Book Club Edition" printed on the inside front flap, and the price is absent (first editions may be price clipped if they were given as gifts). Book club editions are sometimes thinner and always taller (usually a quarter of an inch) than first editions. Book club editions are bound in cardboard, and first editions are bound in cloth (or have at least a cloth spine). 1961, London: Collins Crime Club, January 20, 1961, hardcover
