[3] Generally formidable in appearance, Aunt Agatha is five-foot-nine, with a beaky nose, an eagle eye, and a lot of grey hair.

[4] Agatha had at first been affianced to Percy Craye, though upon reading in the papers of his behaviour at a Covent Garden ball, she had ended the engagement.

[7] Generally, Aunt Agatha tries to make Bertie marry or tells him to do some task that she feels will benefit the family's prestige.

Though Bertie is not financially dependent on her, he has been intimidated by her since he was young and, particularly in the early stories, feels compelled to obey her wishes.

In this story, Aunt Agatha tells Bertie to go to New York to keep his cousin, Gussie, away from the girl he has fallen in love with, Ray Denison.

Aunt Agatha disapproves of Ray because she is a vaudeville performer, and feels that Gussie would disgrace the family by marrying her.

[14] These stories are collected in Very Good, Jeeves, Though she is frequently mentioned, Aunt Agatha does not directly appear in the novels.
