London, Robert Hale, 1960. First edition, first impression. Hardback. A very good copy. Bloch's best-known novel and a highlight of the genre. This is the first UK edition, preceded by the US edition. Condition is very hood with a vertical crease to the jacket and some gentle wear to the edges and spine tips. Price has been covered by a seller's sticker. Largely a nice copy. [8938, Hyraxia Books].
