Three Doors to Death is a collection of Nero Wolfe mystery novellas by Rex Stout, published by the Viking Press in 1950 — itself collected in the omnibus volume Five of a Kind (Viking 1961). The book comprises three stories that first appeared in The American Magazine:

• "Man Alive" (December 1947)
• "Omit Flowers" (November 1948)
• "Door to Death" (June 1949)

• 1950, New York: The Viking Press, April 21, 1950, hardcover^[1]

In his limited-edition pamphlet, Collecting Mystery Fiction #9, Rex Stout's Nero Wolfe Part I, Otto Penzler describes the first edition of Three Doors to Death: "Green cloth, front cover and spine printed with black; rear cover blank. Issued in a mainly reddish-orange dust wrapper."^[2]

In April 2006, Firsts: The Book Collector's Magazine estimated that the first edition of Three Doors to Death had a value of between $300 and $500. The estimate is for a copy in very good to fine condition in a like dustjacket.^[3]

• 1950, New York: Viking (Mystery Guild), August 1950, 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).^[4]
