The ame of the dark and decaying old mansion was spoken only in dread whispers. And yet it was to this isolated place on the rugged English seacoast that the exquisitely lovely young Deborah Chantrey had come--summoned by the master of Mullion Hall, Deborah's uncle and now her guardian. Why had he wanted her to come here, she whispered. Gentle and shy Deborah was out of place among her swashbuckling young cousins. With fear and foreboding she began to suspect the sinister nature of their activites at Mullion Hall.

And then one wild and stormy night Deborah was forced to be their accomplice as she rode with them on a terror-filled journey. Now she too was deeply mired in the evil at Mullion Hall--an evil from which even a deepening love seemed only to increase the hopelessness of escape.
