The Mary Alice Brandon FileEdit
- Main article: The Mary Alice Brandon File
Anna-Marie married Edgar within six months after Edgar's wife Lillian passed away in a supposed "accident". While she treated Cynthia like a pet, she was rather cold toward Alice. Alice became suspicious, given the time it took to prepare the wedding than should have been possible and her off-hand comments. She suspected Anna-Marie to be responsible for her mother's death. By confiding in Edgar about her suspicions, however, she found out that her father was the one who hired an assassin to kill his wife, and that Anna-Marie was in on it all along.
At the town marshal's office, Edgar and Anna-Marie coldly watch Alice get dragged away by nurses after convincing the town marshal that their daughter had gone mad. Alice pulled apart Anna-Marie's pearl necklace before she was whisked away.
Anna-Marie wore her blond hair in a bun and had the round facial features of a young girl. As a person from the 1920s, she used to wear a long necklace made of pearls connected to a silver pendant that followed down to her torso.

Anna-Marie's name was never revealed in the Twilight Saga. Her name was created exclusively for the short film. In The Twilight Saga: The Official Illustrated Guide, Alice's stepmother was known to be a blond Yankee from Illinois who was only ten years older than Alice, and her father was a frequent customer to Mr. Brandon.
