A scarce science fiction title
First edition, first printing hardback in dustwrapper. 20.5 × 13cm, 172pp

They were robots all, very ancient robots, the sole survivors of a once great civilisation. And yet there was a mystery about them, for it soon proved that they represented a level of technology which even the Canistrans had never reached. Then came the hour when Captain John Rogers had to ask himself whether Hansekar was more than a robot, and just what kind of secret he kept hidden in the basement of his palace..."
This copy is in very good condition. There is light wear to the wrapper which has not been price-clipped. There is light foxing to the pages' top edge but the pages are clean and the binding is secure.
