Cagliostro

 was a carnival store holder who had a mummy Khaset which could speak. He was a showman when he presented the mummy on stage. He used it to commit burglaries. He got himself shot in the foot which hindered his escape from the Eighth Doctor and Charlotte Pollard. He told the Doctor how Le Roi found Khaset during the Napoleonic invasion of Egypt and how it came it to be in his possession. (AUDIO: The Mummy Speaks!)
