She is described as a "handsome woman in a masculine weather-beaten way, with a deep hearty voice". She is involved in many activities in Lymstock, such as Guides, the Women's Institute, and various committees, and so keeps herself busy.
She had wanted to be a doctor, but her parents were not willing to pay the tuition fees, even though they paid them readily for her brother.
She was secretly in love with Richard Symmington. When Mrs. Symmington died, Aimée feared that Symmington's governess, Elsie Holland, would have designs to become the second Mrs. Symmington. She decided to send her an anonymous letter to scare Elsie away. She likely hoped that if Elsie showed the letter to the police, it would be regarded as one of the many sent by a posion pen writer. Sadly when Mr. Symmington, the real posion pen writer, figured out what Aimée had done, he decided to use it to put an end to the police investigation by having Aimée arrested. She later planned to travel the world along with Emily Barton.
In the ITV 2006 adaptation of the novel (Episode 2, Series of Agatha Christie's Marple), the name of the character reverts to "Aimée Griffith" and is played by Jessica Hynes. As with the original novel, she was also portrayed as a fairly gossipy woman. She did not approve of the idea, for example, of Megan Hunter staying with Jerry and Joanna Burton after the death of her mother and told Jerry so.
