Obviously from that expression, Inspector Mallory is back. I know people love to hate him. He is definately a curmudgeon. My favorite was the handsome Inspector Sullivan. If you watch the previous episode of Season 8, Ep 10 there is a funny moment when both Inspector Valentine and Inspector Sullivan are back & Mallory is mad & comments to Srgnt Goodfellow about not wanting their "chiselled chins" in his office LOL. Anyway, keeping in mind the effect Covid Restrictions had on filming, this is still a good episode.
