Synopsis by Hal Erickson
The technical wizardry of the IMF is given a real workout in "The Double Circle." Anne Francis guest stars as IMF agent Gillian Colbee, who poses as the owner of a valuable antique. Gillian's impersonation is part of a master plan to recover a stolen rocket fuel formula from mercurial art collector Victor Laszlo (James Patterson). Other vital ingredients to the success of the plan include the precise re-creation of Laszlo's apartment, and a delicate electronic rigging on the villain's private elevator. First seen on November 9, 1969, "The Double Circle" was written by Jerry Ludwig.
