The The Charitable Society of Ladies Who Lunch is an organization that Evelyn Fraser-Hyde is part of. It is comprised of New York women who are wealthy. The goal of the organization is to help those less fortunate through donations of money, time, and companionship. The women in the organization help look after children whose parents are either at work or are looking for work in the Depression.
Evelyn looks after Johnny McMurray every few weeks. During The Adventure Upstate, Evelyn tasks Sadie with looking after Johnny. While Sadie is not an actual member of the society, Evelyn ropes her into helping out with the organizations functions anyway.
