Susan Polk enters into a relationship with her therapist when she is a young girl. Years later, after 20 years of marriage, she will claim she has been abused by her husband for decades.  After he is found dead in their guest house the question would be, was this a case of self-defense or a cold-blooded murder?  Several resources were used in the research of this case including: Court record: The People, Plaintiff and Respondent, v. Susan Mae Polk, Defendant and Applellant, Contra Costa County Super. Ct.
