When I watched this very good episode of CSI: NY I was reminded of the classic Hitchcock movie Strangers on a Train. A movie that CSI alluded to in a past episode. I was also reminded of a past episode of CSI: NY titled "And Here's to You Mrs. Azreal" which had a theme similiar to this episode. However, despite this flaw I found this episode to be one of the best of the season (Which looks to be a little shorter due to the Writers Guild strike) so far. Four seasons and CSI: NY is still going strong. Fantastic.
