There were elements of the episode I really enjoyed. Matt and Ronnie in the field forensicating. ;) Discovering the murder victims were not the intended victims. And having a murder suspect whose motives kept you guessing. But then I felt the episode fell apart as the trial progressed. Are defense attorneys allowed to change their defense mid case in the UK? The ex-wife was portrayed as a selfish, thieving witch before, suddenly, becoming a tearful victim. Then, of course, there was her big WTF revelation discussed above.
And while I like Jake, I'm over his apparently sleeping with every female attorney who has crossed his path. He's really not that irresistible. ;p
