Heres the diary from Mary Maloney's point of view.
Dear diary,
Today, I know that I have done some things which I know I should not have done, particularly killing my husband. However, it is not entirely my fault. We have been together for over 20 years. How could he just suddenly want a divorce. That was totally outrageous. Anyway when the police came, I didn't feel a bit nervous at all. After all I had had practice. The policemen were all fools. They actually ate the murder weapon. They were pretty dumb and gullible. Well since my husbands gone i better get on with life. He deserves it. Who asked him to mess with Mary Maloney....
