Mrs. Holper is a customer of Molly Foster Graham's dress shop. She tried to return a dress with a big whiskey stain on it that she had worn "to the Jaycee thing". Molly argued with her, and told her that the dress wasn't sold to her in that condition, to which Mrs. Holper replied that "she never had any trouble returning dresses before, which was one reason she shopped at my place rather than some others that she knew about".
Molly recounts this story to Will Graham over the phone while he is investigating the "Tooth Fairy" killings.
