Night of the Half-Moon — J.H. Rhodes

Dark, mysterious Ravenwing...It was the terrifying house that had long haunted Anne Brannon's dreams. And when she inherited the place, she was determined to sell it to pay up some family debts. As she drove to the eerie mansion, she knew her plans would be resented by the relatives and servants who were its regular inhabitants. But Anne knew nothing of Norman Franken, Ravenwing's current visitor who hated all change. And even as she drew closer to the forbidding house, she had no idea how far Franken or someone else would go to prevent the sale. Then, in the dark of night, she ran out of gas and was picked up by strangely attractive Craig Allyson, who just happened to be heading for Ravenwing himself.

And the stage was set for Anne's drama of horrors...
