Book: "Bitter Harvest" by Ann Rule

http://www.canoe.ca/JamBooksReviewsB/bitter_rule.html
Bitter Harvest: Debora Green, 
the physician convicted of poisoning her husband, Dr. Michael Farrar, 
and of setting the fire that killed two of her three children is still 
in prison in Topeka, Kansas and her sentence is a "hard 40" years. 
She has worked to train dogs for the handicapped, and writes that she 
spends much of her free time crocheting. Last year, she withdrew her 
appeal for a new trial, realizing that if she failed to prove her innocence, 
she would be risking the death penalty. Debora is adamant that she has 
little memory of the years during her alleged crimes or of her first years 
in prison because she was heavily sedated. Debora's personality is one 
of the most baffling have ever encountered. She insists that the full 
story has never been told. We still correspond from time to time, and 
I may go back to visit her once more as she does want to talk with me.

In fact, we found several thousand cases from 1990 to 1999 involving 
mothers who killed their children, and we researched over 200 of them. 
Approximately 10 percent of these women had killed more than one child. 
However, other than Susan Smith, who drowned her two small sons in 
Union, S.C., most people would find it difficult to name another one 
of these mothers.
