The Delphi Bureau is a top-secret spy cadre answerable only to the U.S. president. The organization may have just one field operative, a supposed researcher named Glenn Garth Gregory. He gets his orders from an in-the-know Washington, D.C. socialite, and he relies on a resource that makes him a one-of-a-kind asset: his photographic memory. This adventure-packed, tongue-in-cheek pilot sets the pace and style for the 1972-73 series it launched. In it, Gregory sets out to find who's behind the disappearance of jets, tanks and other surplus weaponry.
