what happens in part three Immorality ? what's the outcome of henrietta's story?

Bobbette happens to find out, from her friend Gardenia’s brother-in-law who worked at the National Cancer Institute, that Henrietta’s cells are still alive and being used for research. There is more hardship for the family. Deborah dies of a heart attack, Gary dies of a heart attack, Cootie kills himself, Fred dies of throat cancer....Eventually Henrietta will get the recognition that she deserves.
