Lewis, ITV1, review - Telegraph From Sherlock to Barnaby to Poirot, we do grumpy middle-aged men solving obtuse crimes better than anyone. Curmudgeonly old Morse was one of the finest, but Kevin Whately has made a good fist of Lewis (ITV1) too. Amid rumours that it could be his last series, he returned last night, as welcome as your own bed after a long journey. The investigation converged on the botanical gardens, an unusual hub for intrigue and grisly comeuppance, but apart from that all the old elements were in place. There was a Miss Marple-esque vigilante (Celia Imrie), a sinister academic (Alex Jennings) and a foxy woman (Nadine Lewington) for sidekick Hathaway (Laurence Fox) to flirt with. The denouement came in a secret lab underneath the gardens, and as is the rule, the villain turned out to be a well-regarded British character actor. How much easier real-life detective work would be if you could ascertain guilt simply by recognising someone from, you know, that thing, with that other guy. I did briefly wonder how one goes about installing a £2m subterranean medical research facility without attracting any suspicion, but I'm splitting hairs. This was as good as ever. Whately was gruffly ethical. Fox smoked a lot and talked about CS Lewis - he's really the star of the show now, the sidekick usurping the sidekick. Oxford's haughty masonry provided the backdrop.
