A Young Man
The women of Wisteria Lane listen to Mary Alice's therapy tape. They discover that her real name was Angela. Susan convinces the others that they should show Paul the threatening "I know what you did" note. He is shaken, but later tells Lynette and Gabrielle that Mary Alice was "not a well person." She probably wrote the note herself. Gabrielle thinks he's lying. And after Paul hires a private investigator to find out who sent the note, we think so, too. Later, Paul knows Mrs. Huber is the sender of the mysterious Mary Alice note, so he decides to take the matter into his own hands. When he confronts her, she admits she did it and says she's not sorry. Wrong move, Mrs. H. Paul snaps and strangles her to death.
