Greeves

"Oh good heavens!"

- Greeves

Greeves was one of the butlers at Eddison Manor. He was one of the main suspects after his kind of mysterious behaviour. He served at the meal, the one after the murders of Gerald Peach and Chandrakala, and the poisoning of the Doctor. He saved Donna Noble's life after the Vespiform was about to kill Roger Curbishley.

Behind the Scenes
It is possible that his name is pun on the fictional valet Jeeves in the short stories by P. G. Wodehouse.
