First Edition. Very rare Hubin listed mystery and Bleiler listed fantasy novel. Set in 1942 "television in the coming decade furnishes the initial episode in this unique plot. An unclaimed box from Japan in an Express Company auction sale, its counterpart in London revealed by a new transatlantic television process, and a cable of inquiry are the prelude to a wave of murder, violence and intrigue in Chicago". This copy nicely inscribed and signed at front endpaper. Very Good, bit of sunning to spine, couple square inches of cloth discoloration at lower front cover (likely from moisture exposure), in nearly Very Good dustjacket, very shallow loss at spine ends and flap corners, nickel sized chip at top front panel.
