A couple are being harassed by a man in a car, it turns out his son was killed the husband.
It does feel as if the show is once again in the middle of a purple patch, new year, very much a new approach to the show, it's as if a concerted effort was made to freshen things up.
I enjoyed the complexity of the episode, you will probably agree with one party, but the law is very much with the other, it's that clash, that conflict that makes it so interesting.
Whilst Polly is the one who remains professional, cool and level headed, it's hard not to agree with George's feelings on this one, you can almost see the loathing on his face.
Ian Gelder is great as the grief stricken dad, Daniel Ryan, I'm a big fan of, when isn't he cast as the villain of the piece.
Very good, 8/10.
