Taking over the role of “mentor” detective, Lewis returns sans Morse after being widowed and taking a long holiday to drink a lot and forget. Once back in Oxford, he is partnered with a new sergeant (a little less naive than Lewis used to be with Morse, but still pretty green) and they begin protecting Oxford from all things nefarious. The one major difference here between this show and Morse is that the new assistant, Hathaway, is the more cultured, educated one…taking those reins from Morse. Lewis is once again, usually a step behind. So, even though he is Hathaway’s mentor, once could also say Hathaway teaches Lewis a lot too. Excellent stories and wonderful acting really round out this series as a winner. I thought for sure I would be lost without Morse. Yes, Oxford is different without the old guy, but Lewis is a more than capable replacement.
