Mrs. Beale, née Miss Overmore Timeline and Summary

As a governess, Miss Overmore follows Maisie from her mother's house to her father's, saying that she can't bear to be without little Maisie.
Soon enough, though, it's clear that Miss Overmore has other plans: she and Beale start living in sin, using Maisie as a mere pretext for their relationship.
The plot then thickens when, having married Beale, Miss Overmore (now Mrs. Beale) starts seeing Maisie's stepfather, Sir Claude.
Things get even more complicated after that, as Mrs. Beale fights with Mrs. Wix over what Sir Claude should do.
Mrs. Beale remains unwilling to sacrifice Sir Claude, and in the end, she wins him back, having almost lost him following his flight to France.
Mrs. Beale and Sir Claude end up together, just as Maisie and Mrs. Wix do. But Mrs. Beale has made such a nasty scene at the end that we wonder whether "together" really means happily ever after in this case. We think not.
