New York: Robert McBride, 1931. First Edition. The author's first book, one of two "Oberon 'One Week' Winble" detective novel, the other being "The Telltale Telegram" (1932), the author's second and final novel. A Scarlet Thread mystery.
Jacket panels affixed to the book, with "scarlet thread" rubber-stamps on the page edges, all presumed as issued. Light rubbing overall, a few small chips and dampstains, slight lean, and owner inscription (dated 1931) on the front endpaper. Very Good plus overall. Scarce.
