IT IS DECEMBER ON EARTH, AND CHRISTMAS IS approaching. Wilfred Mott is in church when he encounters an enigmatic woman who recounts the legend of the Blue Box and a “sainted physician” who smote a demon in the 1300s. The following day, the woman reappears on Wilf’s television screen. Her message this time is less cryptic: Wilfred must take up arms to protect the Doctor.
At Broadfell Prison, the fanatical followers of the Master bring him back to life by following the detailed instructions he left before his death. But their ceremony is sabotaged, and the tormented Master emerges in dangerously unstable form.
