John Roeburt - The Long Nightmare

Originally published in hardback as "The Climate of Hell" by Abelard-Schuman in 1958. Published in paperback as "The Long Nightmare" by Crest in 1958. This U.K. edition published by Digit (R246) is undated but is circa 1959. Digit tended to swipe cover art - this Barye Phillips image originally appeared on the Crest edition of "Evil in the Night" by Erico Verissimo.
