[1] Narrated by protagonist Chapman Jones ("Chappie"), the stories involve his pulp-style adventures with colleagues Dr. Ken Wilson and others in combating menaces of supernatural horror.

Madame Tara, the old fortune teller living upstairs from Chappie, has been murdered, and her death is investigated by a certain Inspector Ferguson.

While being questioned by Ferguson, Chappie realizes his neighbor must have been involved in something truly occult; the corpse has in hand a scrap of paper inscribed with the Solomonic seal of Belial.

A villainous cabal seeking a magical Egyptian artifact steal and trap the souls of Dr. Wilson and Yalna in order to use their bodies to further their quest.

Chappie and Hassim pursue them through London's seedy night scene in the doctor's Rolls-Royce to thwart the plot and restore their friends.
