Chris Cool, TEEN's brilliant secret agent, investigates international intrigue in the Middle East.

       After probing into a ticklish Turkish caper in New York City, Chris follows the clue of a flaming crescent moon to the exotic city of Istanbul. With the aid of a beautiful Turkish girl, he picks up the trail of his quarry, a vengeful ex-Nazi scientist known as Dr. Death.

       Weird, menacing developments involving a band of fanatical thugs and two objects of antiquity lead Chris and his fellow agent, Geronimo Johnson, to an archaeological dig in Sardis, reputedly haunted by ghosts of fierce whirling dervishes. The daring TEEN agents' hunt for Dr. Death and his political plotters plunge Chris and Geronimo into a dangerous chase in an eerie cone-studded volcanic valley which holds a fantastic treasure and a world-terrifying secret.
