From the back cover of the Signet first edition: "His glowing eyes, light streaming from them, paralyzed me! I was transfixed and while fear climbed into my throat and choked off my breath, he smiled. It was a terrible, knowing smile, inhuman - alien! A shriek of terror died within me as he reached up with an enormous hand and removed it from his gaping mouth. As I cringed helplessly beneath him, the towering figure held the offering before me - the Communion offering of the mysterious Church of the Brotherhood - a pulsing, amorphous object of translucent white jelly. I trembled and gagged. It was alive! As I stared in horror, it transformed itself into a mouth - and smiled!"
