TPC 107: "The Son of Smokeless Fire", by Aaron Vlek
This time The Librarian sends Frank on a caper to foreign shores where he gets a taste of magical beasties he’s never even heard of before - Cairo! In that city teeming with ancient magics Frank comes face to face with a jinn, scads of them, including an old friend of The Librarian’s. Frank finds himself blindfolded and marched at sword point out into the desert where he meets a thoroughly revolting congregation of miscreants and the pernicious tome they worship. He was told by the jinn that its nefarious author was long dead these many centuries, but can one ever be certain of anything where the jinn are concerned. Ever heard of the Necronomicon?
