"Bitter End" is the first Nero Wolfe mystery novella by Rex Stout, originally published in the November 1940 issue of The American Magazine. The story is a re-working of Stout's Tecumseh Fox story Bad for Business, published later that year. "Bitter End" first appeared in book form in the posthumous limited-edition collection Corsage: A Bouquet of Rex Stout and Nero Wolfe edited by Michael Bourne, published in 1977 by James A. Rock & Co., Publishers. It subsequently appeared in Death Times Three, published by Bantam Books in 1985.
