Cuthbert Simpson was a Time Lord pursuing the Doctor. He took on the role of butler and general servant to George and Elizabeth Wallace in Banquo Manor.
Biography
Finding the Doctor
Using quantum extrapolation, the Time Lords predicted where the Doctor would next visit. There were several hundred possibilities, Simpson was sent to Banquo Manor in 1898. He served there for 100 years before the Doctor's arrival.
At Banquo Manor
Simpson's had his own quarters; they were located under the stairs. He resented visitors from coming in. The room was well organised with everything in neat piles. When Richard Harries arrived to perform his experiments at the manor, all the staff apart from Simpson and the maid, Beryl Green, were dismissed.
Simpson was present at Harries experiment. Harries was killed when his headset overloaded; Simpson helped retrieve the body when it fell into the fiery wreckage of the machine. He was interviewed by Inspector Ian Stratford and his colleague, Sergeant Baker; they were treating the death as murder.
Simpson informed Ian that he had seen Dr. Friedlander (the Doctor) and his associate, Fitz Kreiner, near Harries' lab in the conservatory, shortly before his death.
Simpson and Beryl found the body of Harries' returned to its former place in the master bedroom. It had been missing for some time after it was stolen. Simpson left Beryl to recover from the shock while he went to tell Stratford. On their return, Beryl was found dead.
Simpson fetched the manor's shotgun for Stratford after the murder of George and Elizabeth. He used it to shoot Harries when he came back to life. Harries then knocked him through a banister, injuring him.
Stratford and Hopkinson carried him as they ran. The residents barricaded themselves into the room. Friedlander deduced that when Catherine fell unconscious during the experiment connection was made with Harries. He was acting as her subconscious dictated. She halted him by thinking hard. Simpson was unable to move greatly due to his leg injury.
Catherine left with Harries. She was controlling him all along, having the residents killed. Harries returned and tore Simpson's eyes out. He then escaped with the rest through the window. However, the others had climbed down; Simpson's injuries meant that he fell. (EDA: The Banquo Legacy)
Personality
Most thought Simpson to be constantly smug. John Hopkinson considered his voice to have a constant condescending tone. He faithfully served George, attending to his problems and helping him out.
Although he maintained a normal tone of voice, Simpson was upset at the death of Beryl. Even near death he refused to give the Doctor the inhibitor. (DW: The Banquo Legacy)
