Usually I do not enjoy CSI: New York as much as I do CSI: Vegas but this episode was different and exceptionally brilliant. I never expected the sister of the murdered guy to be crazy. She seemed quite sane to begin with although I did think that she committed the murder out of malice. In other words, something about her story did not sound quite right but I was genuinely shocked when I realized what had actually happened.
I was also happy with the extra bit of focus on the private lives of the characters. I am really looking forward to finding out how Stella tested and I was happy to see Mac and Peyton - we hadn't seen much of their relationship for a while before this.
All in all, a suspenseful, well-written, well-acted episode.
