In Gennifer Choldenko's Al Capone Does My Shirts , Piper Williams is a world-class schemer who manages to get her friends into plenty of trouble. Piper is the daughter of the warden at Alcatraz prison, and she lives on the island with her family. Other families live there, too, including...
that Moose Flanagan (the story'sprotagonist and narrator).
Piper comes up with the idea of selling prison laundry services to the island kids' classmates. For a small fee, the kids can brag that their laundry has been washed by the likes of Al Capone. Moose refuses to participate in this scheme, but when all the kids get caught, he has to share the blame because he knew about it and didn't try to stop it or tell anyone.
The warden scolds everyone but Piper and even threatens that if the kids break the rules again, he will fire their fathers. Piper seems to get off with no consequences, but this is not actually so. For a while after the laundry scheme, Piper goes to live off island with her grandmother on Nob Hill. One of the other kids says that this is her punishment for the laundry scheme, but Piper downplays it and says that she is just "sick to death" of the other kids. Moose is glad Piper is gone. "It makes everything easier," he explains.
