Mrs. French is a character who appeared in Double Down. Susan Heffley hired her for private lessons to teach Greg to play the piano. Mrs. French also owns a Beginner's Songbook. She is known to give up easily on kids who aren't very good at learning the piano, as she stopped helping Greg after a few lessons, and eventually Greg and Mrs. French did their own things during the lessons. Eventually, Susan Heffley saw what was happening and ended the private lessons for Greg teaching the piano lessons. Luckily, she got back with him that the piano was not suitable for Greg and he will have to play the other musical instrument instead.
