Title: Ultimate betrayal
Description: "When the mansion of Dr. Debora Green and her separated husband burned to ashes, killing two of their three children, arson was immediately suspected. In this program, police investigators apply pyroanalysis, hair analysis, and old-fashioned questioning to link Debora to the crime and toxicology to determine that she had been slowly poisoning her unfaithful husband with deadly castor beans as well. Faced with probable conviction, Debora confessed to all charges."--Container.
