New York, Henry Waterson Company, 1927. First edition, first impression. Hardback. A very good copy. A story of criminals with the power of invisibility! Chipping to the jacket particularly at the spine tips, some dustiness and a little bumping. Lengthy tear to the spine covering probably 60% of the length, fixed with brown tape to the reverse. Small ink price stamp. [10834, Hyraxia Books].
