Unlike some villains who are easily fooled, Aranda is sharp and constantly looks for flaws in the IMF’s story.

The IMF must prevent from seizing the throne of a small African nation. Since the rightful heir is missing, the team uses a blind, elderly woman and a "miraculous" discovery to verify a new claimant. Director: Alexander Singer Written by: Robert E. Thompson Original Air Date: October 20, 1968

If you’re interested in more details, I can provide a of the climax or a list of other high-stakes episodes from Season 3.

The IMF relies on psychological manipulation and theatrical effects rather than brute force.

The science is typical 1960s "tech-magic," but the suspense comes from whether the Queen will react as the IMF predicts.
