Cuthbert Simpson Cuthbert Simpson was a Time Lord who pursued the Eighth Doctor . He became the butler 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 a century before the Doctor ' s arrival . During this time , Simpson set up an Artron inhibitor to drain the Artron energy from the Doctor ' s TARDIS should it land . Another of its effects was to prevent any nearby Time Lords from regenerating . At Banquo Manor . Simpson had his own room under the stairs . He resented visitors entering . 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 implanted Harries ' rat s with nano - cam s and used them to keep tabs on the residents . 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 . When Friedlander went for a walk , Simpson attacked him and believed that he had killed him . Simpson and Beryl found the body of Harries returned to its former place in the master bedroom . It was believed to have been 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 ' re - animated body . Harries then knocked him through a banister , breaking his leg . Friedlander joined them , unaware who had attacked him . Stratford and Hopkinson carried him as they ran . The residents barricaded themselves into the room . Friedlander deduce d 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 easily 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 climbed down ; Simpson ' s injuries meant that he fell and was gravely injured . Despite his blindness he was still able to see via the rats . He then seemingly died of his injuries , unable to regenerate due to his Artron inhibitor . Gaining the code . However , Simpson had not died ; it took him fifty years to recover from his injuries and another twenty to find Susan Seymour . He visited her and she gave him the randomiser seed code for the Doctor ' s TARDIS and the accounts of her late husband , Hopkinson and also those of Richard Harries . Simpson could only read these via the nano - cams in the rats . He then transmitted this information to Gallifrey . ( PROSE : " The Banquo Legacy " ) Personality . Most thought Simpson to be constantly smug . John Hopkinson considered his voice to have a condescending tone . He faithfully served George , attending to his problems and helping him out . Although he maintained his normal tone of voice , Simpson was upset at the death of Beryl . Even near death , he refused to give the Doctor the inhibitor and when he finally learnt the Doctor ' s randomiser seed , Simpson looked forward to returning home . ( PROSE : " The Banquo Legacy " )
