No Defense by Kate Wilhelm

What do you do when there really seems to be no evidence that can help your case?  A man has died and everything points to his wife.  She is adamant that she did not do it.  Cryptic clues had been left and the lawyers had to dig through years and years of information that did not seem to have anything to do with his death.  As they dug into the histories of people who had been involved with this mans life more things start to come to life.  There were many twists and turns and things that took me by surprise.  One thing that is true is that you can't escape history, it can come back and bite you in the butt.
