Fran

Fran was Harlan's housekeeper. She apparently loved working for Harlan but couldn't stand his family, especially Ransom.

Personality
Fran was friendly and nice to Harlan Thrombey and Marta Cabrera but she wasn't quite as pleasant as Marta as she had a much more difficult time dealing with the rest of the Thrombey family. She especially despises Ransom and had a hunch he played a part in Harlan's death from the beginning.

Trivia

 * Despite the movie being a whodunit style murder mystery, Fran is the only person that actually gets murdered and the plot doesn't revolve around her death.
