HOUSE OF UNHAPPINESS The mansion on Telegraph Hill had been the scene of many tragic deaths. Arlene Dade's parents had moved away from it because of its overwhelming air of gloom and darkness. Now they too were dead, and the house was hers. Would it bring another tragedy to her, or could it hold the chance for a bright new life? She didn't know. And she had many doubts about her new husband, the dashing but unpredictable Alan Caswell. Did he love her, or was he merely using her as a key to unlock a hidden fortune? Did the fog outside hold menace...and was there a worse, more sinister fog within?
