Manslaughter by Alice Duer Miller

It was noticeable -- though no one noticed it -- that a month after Lydia went to work in Mrs. Galton's organization everyone in her immediate circle was doing something for released convicts. Bobby, Miss Bennett, Eleanor, Wiley, all suddenly began to think that the problem of the criminal was the most important, the most vital, the most interesting problem in the world. The explanation was simple: A will like Lydia's, harnessed to a constructive purpose, was far more irresistible than in the old days when it had been selfish, spasmodic and undisciplined.

She was given a little office, like Miss Galton's, and she was in it every morning at nine o'clock. Miss Bennett, who had worried all her life because Lydia led an irregular, aimless, idle existence, now worried even more because her working hours were long.
