After 18 years in jail, Jeremy Kent obtains a retrial for the brutal murder of lonely old Thomas Harrott during a robberies spree. It was Catherine's first unsupervised case and far from up to since much stricter evidence rules. While she and captain Brass just race to uphold the conviction, Nicks spearheads the unbiased search for the truth. After the murder weapon, a hammer, is finally found, and the emergency services' recording expertly analyzed, the plot proves more complicated then anyone anticipated, with major consequences for more people then Kent.

Did You Know?


After finding the hammer, they say that the tree grew around it and preserved the prints. However, this process would have taken months or years to occur. Until the hammer was encased by the tree it was exposed to bacteria, insects and all kinds of weather. This would have destroyed almost all traces of the fingerprints and made any kind of print match impossible. It would have also degraded any DNA in the blood and made any genetic match to the victim or suspect(s) impossible. See more »

By far the best episode of CSI in a while
24 April 2009 | by (United States) – See all my reviews

After last week's mess of an episode, CSI proves that it's not lost its touch yet. This was one of the better episodes this season. Marg is finally given the opportunity to shine as the star of the show and she makes it count, delivering one of her finest performances. I have always felt that she should have been the one to replace Peterson as the star f the show. Nothing against Fishburne, I liked that they brought him in, he's a great actor, but this should have been Marg's show, and she shows why in this episode. The supporting cast was good too. I liked the plot, and thought that the ending wasn't too predictable. You kind of saw parts of it coming, but it wasn't that bad. I thought the resolution was actually solid and made sense. There were a few factual errors here and there, but nothing too egregious. CSI has found the right path again, let's hope they don't wander off again. Well done CBS, keep it up!
