Prentiss learns from an old friend, John Cooley, that their mutual friend, Matthew Benton, just died from a heart attack. Prentiss had not seen either man in several years, both for different reasons. John also mentions that Matthew thought he was going to be killed just like "T. Valentine". In searching, Garcia does find someone matching that name in the area who recently died from dehydration. There are similarities between the two deaths but no medical rationale for tying the two together as murders. A third person in the area then dies in a similar way but again no medical indication of an unnatural death or rationale tying the death to the first two. However, Prentiss and Rossi, in particular within the team, are certain the three deaths are related and that they are indeed murders. They have to tread lightly and carefully since the families of the deceased refuse to speak to the FBI - especially Matthew's family who know, and do not like, Prentiss - and since there is no ...

When Prentiss and Morgan pull up outside the house near the end of the episode, it is pouring rain, they are even wet when they enter the house. However, when they leave the house it is gently snowing. Its not unusual for rain to turn to snow.

Solid Episode
2 May 2012 | by (United States) – See all my reviews

This will be a short review because the other reviews have covered the details well. I will just add that as a different sort of episode, I liked the departure from the more standard, easily explainable killers. There is a touch of the unexplained , not too much, just a little hint of it that I really enjoyed. The idea of having good Vs. evil where the lines are not so clearly drawn is always interesting. I mostly want to warn that after a really good episode, thy completely blow it with the music at the end. It was the most inappropriate music, especially given what happens. I really can't even stress enough how bad it was. Hit the mute button as soon as it starts for full enjoyment.
