Doctor Identifies Master’s Hypnotic Scheme

In the Brigadier’s office, Chin Lee recounts her fragmented memories of meeting Professor Keller (the Master in disguise) at an embassy reception, where he invited her to Stangmoor Prison under the pretense of discussing prison reform. When pressed for details about her visit, she struggles to recall anything specific, her mind clouding over—a telltale sign of post-hypnotic suggestion. The Doctor immediately recognizes the pattern, deducing that Keller’s true identity is the Master, who has been using advanced hypnotic techniques to manipulate delegates like Chin Lee. This revelation confirms the Master’s broader plot: leveraging Stangmoor’s technology to control key individuals and trigger a global conflict by hijacking a UNIT nuclear missile. The moment marks a critical turning point, as the Doctor’s realization forces the narrative toward direct confrontation with the Master’s escalating scheme.
