New York: Vanguard, 1931. First Edition. Fine in an about Fine dust jacket, with only minute traces of soil on the rear panel. Stout's seventh book and third hardcover title, one of eight novels written prior to his first mystery, "Fer-de-lance," in 1934. The story concerns Marvin Tasker, director of the Marvin Tasker Musical Institute, who spends a lifetime in an effort to break down love into verifiable, scientific terms. A superb copy.
