Definitely an episode worth catching, even if you've been a bit wearied by the past couple of seasons of SVU. The beginning isn't much to write home about, but things start to speed up once Detective Ash Ramsey is introduced. Naveen Andrews plays the role with aplomb, bringing a breath of fresh air into the SVU cast and characters. The story is fairly simple and isn't so much about finding out who did it as trying to find evidence to convict the killer. Throw in a couple of appearances by the Chief of D's, who, as always, is trying to keep things from being a political catastrophe, a bit of intrigue that involves Benson playing the dominant, and a fast-paced ending that will have you alternately upset and cheering, and the greater part of the episode is a good example of what works.
Downsides were Benson's nasty attack on people who like BDSM play after trapping the head of a foundation with her dominant act, the complete lack of Munch and the totally unnecessary moment of Benson-Stabler tension (because boohoo, my partner wants to do something without me).
