New York, Manhattanville Press, 1928. First edition, first impression. Hardback. A very good copy in the scarce jacket. Involves a device that reads details of a murder from the walls [JC/SFE]. We haven't seen a copy in the jacket before. Jacket rubbed to the edges, quite heavily in places with areas of creasing and short tears. Tape reinforcement along most of the top and bottom edges. Appears to be price-clipped to the rear. [10053, Hyraxia Books].
