Again hansom-cabbing around London In the Devil's Footsteps, psychics Dr. and Mrs. Caspian seek to tune into the wavelengths of Ilona, mind-bending priestess of a cult devoted to alchemy, immortality, the zodiac, and suicide. Two deaths--by water and earth--have already occurred; deaths by air and fire will follow unless the Caspians can dispel the bad vibes that hover around a sweet young thing and the sweet, older thing who just married the sweet young's papa. Not lurid enough? And a bisexual pornographer and his teen trollop in residence. Dip into this heavily perfumed vial only if in dire need of ""a susurration like the tug of tipples on shingles."" And have the fumigator on hand.
