Zebra Books, 1979. FIRST EDITION, Second printing #89083. Soft cover. SIGNED BY AUTHOR on title page. Illustrated wraps embossed with reptilian arm holding a goblet of apparently lethal liquid. Very good condition, perhaps unread, tight, bright, clean, square, no reading creases or damage of any kind. Slight yellowing to inside covers and pages, minimal edgewear. "They all sensed something evil lurking in the shadows, but no one dared mention it--until they were caught in the deadly grip of THE CUNNING." The author of PSYCHO once again scares the marrow out of our bones. An increasingly scarce title in any edition. Excellent addition for the Robert Bloch completist collection.
