Doctor uncovers ship sinkings conspiracy

The Doctor and Jo arrive at the island prison to visit the Master, only to find Colonel Trenchard dismissive of their concerns. His casual mention of recent ship disappearances sparks the Doctor’s suspicion while Trenchard boasts about his security measures, including guards immune to hypnotism. The Doctor presses about the Master’s behavior, hinting at unchecked influence behind bars. What begins as a formal visitation quickly shifts into an investigation of global threats, as Trenchard’s offhand comments reveal a pattern far more dangerous than either realizes.
