Alastair Lethbridge-Stewart

Brigade Leader Alistair Lethbridge-Stewart was a high ranking member of the Republican Security Forces in a parallel universe. He was in charge of security at the Eastchester Scientific Labour Camp.

He was born on an Earth that existed in between the parallel universe and the normal universe. He was saved from that world by Colonel Alistair Lethbridge-Stewart and Major James Lethbridge-Stewart. His travel across realities cost him his left eye, and he was brought to the attention of Gordon Lethbridge-Stewart, the Director of External Security, who had lost his son, Alistair, some eighteen years earlier.

Unlike his counterpart, the Brigade Leader was clean-shaven. He captured and interrogated the Third Doctor, who had just arrived from his own universe. At first he had trouble believing the Doctor's story of having come from another dimension.

It eventually became clear that the Doctor had been telling the truth and the penetration of his Earth's crust would devastate the planet beyond recovery. He threatened to shoot the Doctor unless the Time Lord rescued him, Section Leader Shaw and Petra Williams, but instead the Section Leader shot him dead with her own revolver to save the other Earth.

Behind the scenes

 * Nicholas Courtney, of course, played the part without the Brigadier's trademark (false) moustache.
 * Dialogue in Inferno only refers to the Brigade Leader by his title and last name, but not by his first name.
 * In the novelisation, the Brigade Leader confirmed that he was called Brigade Leader Lethbridge-Stewart.
