One word: excellent. This is by far the best episode of the seventh season of CSI to date. Terrific nail biting suspense that will keep viewers guessing to the very end. It's all capped off with an absolutely spectatcular climax. In the end I actually found myself feeling very sad about the death of Keppler. Very rarely do viewers feel genuine emotion for a character in this or any show. This episode will make many people emotional guaranteed. Now in its seventh season CSI continues to be one of the best shows on television.
