Lewis ITV, 9pm
It’s 10 years since Kevin Whately returned to the Morse universe to play Robbie Lewis. In that time, this spin-off series has become hugely popular - almost as big as the drama that spawned it - and is a global success. It looks set to continue for some time too, because the standard of the scripts is as high as ever. The latest run begins with a two-part case for Lewis and his sidekick Hathaway. The duo have a new boss to contend with - Chief Superintendent Moody - who isn’t sure that Lewis should have come out of retirement, putting pressure on the detective.
