Not sure why the reviews for this ep are so low. This is a very good episode. One of those eps that you think is by-the-numbers but things change very quickly. Done realistically and very good suspension of disbelief (the twists in the episode are based on a something that would never happen, but they are something that really could happen, at least as they are presented here.) Very well done. No Grissom or Willows, but cut them some slack for a great episode.
