NEL, London, 1976, 1^st/1^st.  ISBN 0-450-02559-4.  MMPB, 190 pages.  Wraps show some edge and cover wear, small lower front corner crease, light impressions, faint reading creases on spine.  Binding sound.  Interior clean and unmarked with lightly tanning pages.  ‘In a nightmare second, Liz Frele simply, suddenly, vanishes and her husband, Peter, losing both wife and happiness in that one moment, begins a frantic search to find her – ‘whoever or whatever she is’ – for Liz was not what she seemed.  Pete’s search leads him to Morocco, to the mysterious Dr. Raven and to the world of the occult.  But he is only a pawn in their game.  The Powers of Darkness are everywhere, and he becomes part of an irrevocable pattern of evil where the boundaries between truth and illusion are as evanescent as his joy had been.  Was there ever a Liz Frele?’ (from rear wrap)
