French Catholic churchman who, in 1572, was involved in a plot to assassinate the leading Protestant statesman Admiral de Coligny. The Doctor's companion Steven Taylor met a servant girl who had run away from his household, after hearing threats of a massacre of the Protestant Huguenots. When Steven met the Abbot, he discovered that he was identical in appearance to the Doctor, and for a time he thought it was his friend masquerading as the cleric. When the assassination failed, the Abbot was blamed, and killed on the orders of Marshal Tavannes.
- No images of the Abbot exist, as this story is entirely lost apart from the soundtrack and a handful of photos.
- There never has been anyone with the title of Abbot of Amboise. The story contains a number of real historical figures, but he is not one of them.
Played by William Hartnell. Appearances: The Massacre (1966).
