Doctor exposes Trenchard Master conspiracy

The Doctor and Jo piece together the threads of deception after Smedley reports an officer stealing equipment and assaulting him. Jo recognizes the description as the Master, who should be imprisoned, while the Doctor deduces Colonel Trenchard’s involvement by noting his suspicious timing. Trenchard’s earlier talk of a golf tournament ironically highlights his cover for the Master’s activities. This moment forces Hart to confront the conspiracy unfolding under his command, as the Doctor seizes control of the investigation and demands immediate transport to pursue the escaped antagonist.
