The opening music and high class cocktail party in this episode lulls viewers into thinking that this episode is gonna feature a murder at a high class social function (something that certainly has been done before). Instead it focuses on the rape of a woman as she makes her way through Central Park by herself in the dead of night (something not even I would do).
Due to the nature of the case, Stella gets rather emotionally attached to the victim to the point that Mac has to remind her to focus on her job and not the victim. In the end, she manages to find her suspect and, much to his dismay for reasons I won't mention, arrest him. She also has a moment where she completely tells off the victim's father after he makes a sexist comment about how boys are tougher than girls.
The secondary crime which involves a dealer who was shot by a revolver is a nice contrast and offers some humorous moments between Aiden, Mac, and the exterminator. In the initial crime scene processing she has a minorly creepy moment with the way she comments on her speculation of the weapon. As she says "I guess the murder weapon is a revolver" is rather hilariously creepy with her neutral expression. Aiden and Mac also have a great moment with the general 'I don't care' attitude when the exterminator is giving an endless speech about his job to the two.
Bill Brown also does a wonderful job with composing the music in this episode, especially the transition between Stella processing the vic and Danny processing the evidence as the transition between the songs is seamless.
