Have to say I enjoyed the first review here, "Different but PC" very much, as the reviewer describes all the different minorities and physically challenged who appeared in this episode.
DCI Vera Stanhope investigates that death of a man found in a slurry pit on a farm owned by Danny Pryor. It is found that he was strangled before being weighted down and thrown in.
When Vera sees that the man had a tattoo removed, a Romani one, she turns her investigation toward a Kosovoan worker, Goran Vlasic, who works on the Pryor farm. The head of the "travelers" identifies the man as Jack Reeves. Reeves is estranged from his parents, who didn't seem to know he was living in the area.
Then another migrant farm worker is killed. It seems to Vera that all the action centers on the farm.
Very good episode, and a poignant one, with Vera unaggressively asking very important questions and calling people "pet." The acting is terrific, with a standout performance by Jennifer Hennessey, as Jack Reeves' mother.
Brenda Blethyn really becomes Vera, so much so that it's hard to imagine her doing anything else. But of course she has, and brilliantly.
