Geoffrey de Lacy
Sir Geoffrey de Lacy was an English knight and a cousin of Ranulf Fitzwilliam.
Biography
De lacy went to London to swear the Crusader's Oath before King John of England and upon his journey back to Fitzwilliam Castle he met with Sir Giles Estram - in reality, the Master - who had him arrested and taken before Kamelion, who was in the guise of the King.
The King freed him in favour of executing Estram, but the Fifth Doctor ordered that he be taken down to the dungeons. This was in fact a ploy so that he could show the Doctor the way and, once they arrived, he was freed. The Doctor told him to return to London and warn the King. As he rode from the castle a guard, acting on the Master's orders, shot him with a crossbow. He was returned to the castle where he uttered the words "The King... Doctor... Seek", before he died.
