Black aura

Thackery Phin, the delightfully eccentric American University philosopher turned detective, is attracted to the headquarters of a spiritualistic group and the beginning of his second case.When a rock star is killed after trying to levitate from a fourth story window, and another member disappears behind a locked door while demonstrating astral projection, Phin begins to suspect that the members of the society may be involved in something far blacker than seances.The curse of an Egyptian amulet, a dark seance parlor, lurking death in an orgone box, psychic poison and live burial--Sladek's brainteaser fairly creeps with fiendish happenings.
