Extremely well done portrayal of the hunt for the infamous "Yorkshire Ripper"! Alun Armstrong is superb as the main character, Assist Chief Const George Olfield. He and Richard Ridings, as Det Supt Dick Holland, are excellent and with a great supporting cast who retell this grim chapter in 20th Century England very convincingly and accurately. I'm mystified why these two stars aren't heading the main cast line-up on this web-page. They deserve so much credit.
