London, George Allen & Unwin, 1933. First edition, first impression. Hardback. A very good copy. Inscribed by the author. An uncommon book. A science fiction piece and his second novel, this one involving an increase in the sensitivity of smell. Some chipping to the spine tips, some toning to the spine, a few short tears, some tanning. The price has been 'clipped' (i.e. torn off). Pencil lines have at one point been drawn across the endpaper. [9639, Hyraxia Books].
