Pierre Bedard was an Immortal with a reputation as a master forger. When he found the newly Immortal woman, Felice Martén in 1714, just recovering from her first death, he kept her as a plaything. She learned by watching him, both in questions of Immortality and forgery.
Bedard kept her with him until he grew tired of her, and when he tried to take her head, he learned exactly what she had managed to assimilate, and lost his head to her.
