"The Werewolf of Paris" was a #1 "New York Times" bestseller upon publication. The thriller went through numerous printings of the clothbound first edition (pictured above right), now increasingly rare. It is rumored that Endore, suffering under the impact of the Great Depression, sold the manuscript outright to Farrar & Rinehart for a flat fee, thus receiving no additional royalties from its subsequent success. Given that Endore's next novel, "Babouk" (1934), was published by the leftist Vanguard Press, this story could have merit, although that work's revolutionary Haitian subject matter might simply have proven too controversial for Farrar & Rinehart.
