Synopsis: Publisher: Spectre of Doom. When world-famous spiritualist Sigmund Foster went to his death, he left behind a fabulous estate -- and legacy of towering evil that would draw Gail Canby to the brink of madness. For no sooner had Gail come to his fabled manor than she was caught between greedy relatives clamoring for spoils, and the far more deadly appetite of the spirit that watched her from the darkness of the nether world. Now the wrath of the mad magician was upon all who dwelt at the accursed Willow House -- at treasure palace that threatened to entomb them in a terrifying maze of magic and destruction unleashed from beyond the grave.
