While the second half of this episode takes paths all over the place, getting to the end the long way, it's an engaging plot. Helen Mirren is one of the our greatest actresses, as her movie roles will attest. Her Jane Tennison continues, facing demons of her own making. Her drinking continues and she gets downright abusive and mean spirited when her father dies. Her sister gets the brunt of the abuse (we don't know very much about her, except she is jealous). She continues her investigation into the murder of the young girl. She finally attends an AA meeting, but it is obvious her heart isn't in it. However, at the meeting, she meets Bill Otley, her longtime adversary. It has been years and he sincerely apologizes to her. They renew a friendship, but, sadly, as she confronts a young suspect, the guy pulls a gun in a parking lot and kills Bill. I won't say more than we find out her murder victim was pregnant at fourteen and this stirs the pot of suspects. Her circle is quite large. There are several diversions as we plod toward the end. I found the ending a bit contrived but it was still satisfying. I'm glad to have chanced upon this series on Hulu. I had never heard of it. It is top quality television, done in a superior way.
