SVU: "You'll never break another promise to me"

I am going to try my best to summarize what happened on last night's Law & Order: SVU, but if you ever get a chance to watch the episode - which guest starred Eric McCormack - I suggest you do because it was pretty great.

A woman is found dead from strangulation and stuffed naked into a suitcase, which had been thrown from the window of a moving train heading to Florida. The detectives find out that she is a member of a website where younger attractive woman can go if they are in need of a "sugar daddy." The detectives also do some digging and find out that the owner of the website bought it shortly after going on a date with the dead woman. Apparently, they were in love, or at least up until a few hours before her death.

The man, once in police custody, keeps trying to confess and even proclaims guilt while at arraignment. His lawyer announces that he plans to argue that his client was so extremely stressed that he just snapped. So the detectives go through surveillance footage hoping to find him on it to get a glimpse at his facial expression either before or after the murder.

When the detectives cannot find any evidence of the man ever even being at the train station before the murder, they get suspicious and realize the woman they thought was the murdered girl entering the train was really the man's daughter masquerading as the girlfriend. The daughter was the one who really killed her. The father found them and decided that no matter how much he loved his girlfriend, he loved his daughter more so he promised to take the fall for the murder if it came to that. The daughter tells the detectives that this must be proof that he loves her. But he also made the promise to her that he would keep her safe, so when she is arrested she turns on the father and actually kills him by stabbing him in the neck with scissors. She refused to allow her father to disappoint her again.

I gasped rather loudly when the twist at the end happened. As I said at the top, this was a good episode. Catch it next time it is on. It's worth it.
