How does Emily De Quincey show her generosity and determination in the novel, Murder as a Fine Art?

During the investigation, Emily works alone to make sure that a group of prostitutes will be able to live on a farm and become healthy by enjoying clean air and growing vegetables. She sees that a young acrobatic beggar will be given tuition and board at a school that is commendable and the undertaker will be paid the sixteen pounds he requires for funeral services for the first set of Brookline's victims. She makes sure that her father's promise to the beggars that food will be provided in abundance for the next year is honored by Lord Palmerston and that she and her father have somewhere to stay other than the house arranged for them by Brookline.
