London, Hodder & Stoughton, 1959. First Edition. First Impression. Hardback. A near fine copy. Quite uncommon, but not impossible. An alien invasion piece, made into a 1967 film with Christopher Lee [Clute & Nicholls, p742]. Block a little foxed, jacket a little nibbled to head and tail of spine, but excellent for the year. Slight bumping to the spine tips. Cover art by Peter Rudland [7586, Hyraxia Books].
