The series is moving beyond the early episodes' introductions and careful explanations to show a quicker pace through the mystery plot. Patrick Jane provides the dazzle, as usual, but he also helps unravel significant parts of the mystery. He's always watching the various suspects, and it's fascinating to try to see what he does. Some of his outrageous behaviour is a little unbelievable, but it's tv and it should be fun.
I've never been one to try to solve the case before the detectives, and I don't think the show is really designed for that. Perhaps you are given all the clues to put it together yourself, but it seems more like a magic trick. You're supposed to be amazed by Jane and his leaps that turn out to be right. You're supposed to be impressed and reassured by the CBI agents.
The high point was the human interaction, Jane with the team and with the family of the murder victim. He's flirtatious, charming, serious and intense, and much of the show is all about him and who he chooses to find interesting. The tie-in with the market failure is timely, and the dead banker gets justice.
