BEWARE... THE BLACK ORDER! So comes the warning from the spirit of Myra Maynard's father, who reaches out to her from beyond the grave to warn her of danger from the masters of the occult arts that lurk in the shadows and mark her for murder on her eighteenth birthday. Only the world's first psychic detective, Dr. Payson Alden, and his friend Haji the Brahman mystic, can save clairvoyant Myra from the terrors of The Grand Master of the Order, who tries to claim not only her fortune but her life by means of suicide-inducing spells, invasion of her chamber by spirit assassins, and even reanimation of the dead by a fire elemental. Alden and Haji show Myra how to tap into her own psychic powers and use automatic writing, crystal gazing and astral projection in what becomes a battle of wills between her and the malevolent Master, who finally resorts to conjuring a "thought monster" from the hatred of fifteen men in his attempt to destroy the innocent girl.
