I am looking for, in VG or better condition, the following paperbacks by R. Chetwynd Hayes: The Unbidden & Cold Terror. I am only looking for the 1st U.K. paperback editions (I believe that both were published by Tandem). The Unbidden has the Medusa on the cover, Cold Terror has a photograph of a frightened woman with a tarantula on her. Thanks!
You have good taste. I love R. Chetwynd Hayes too, and am always in search of old paperbacks of his (which I would borrow avidly from my local library way back in the 1970s). However, they are very hard to get in good condition now, although I have managed to get two off an online book stockist.
