[1] Released in 1977 this is the third of the Jack Flanders adventure series, and combines elements of Americana and Old-time radio with metaphysical concepts such as Sufi wisdom and Tibetan Buddhism.

Jack Flanders is approached by a mysterious research institute; the head of one of its departments, Jack's uncle Sir Seymour Jowls (brother to Lord Henry Jowls who was introduced in The Fourth Tower of Inverness) claims to have discovered the location of the fabled City of The Ah-Has, the source of the great ideas and inventions of the future, in the keeping of the higher powers, for their timely release to mankind.

Sir Seymour wants Jack to go to the city and steal the Ah-Ha of the grand Unified Field Theory.

Seeking the help of Chief Wampum, Jack travels to the land of the City of Ah-Has, meeting a pesky troll and an eccentric wizard along the way before he must face the perils of the great city itself - source of the haunting music ("Angel Baby") that Jack has pursued through dimensions, demons and dire deeds...

Chief Wampum's role is clearly a homage, albeit a comedic one, to Don Juan Matus, the Yaqui shaman from the writings of Carlos Castaneda.
