Lewis is a British television detective drama made as a spin-off from Inspector Morse. Like that series, it was set primarily in Oxford, England. Kevin Whately reprised his character Robert "Robbie" Lewis, who had been Morse's sergeant in the original series. Lewis had now been promoted to detective inspector and was assisted by DS James Hathaway, portrayed by Laurence Fox.
The series was produced for ITV. Following the broadcast of a pilot in 2006, a first series of three episodes was broadcast in February and March 2007. A second series of four episodes was broadcast in early 2008. A third series of four episodes was broadcast on ITV from March to April 2009, but this was not shown in Scotland. A fourth series was broadcast throughout the UK from 2 May 2010, a fifth series from 3 April 2011, and a sixth series from 16 May 2012, each again of four episodes. The final, seventh series, was broadcast from 7 January to 11 February 2013, and consisted of three two-part stories.
PBS broadcast the series, as Inspector Lewis, in the United States and Canada, as part of its Masterpiece Mystery series.
In May 2012, after the show was renewed for a seventh series, Fox told The Daily Telegraph it would be its last, as both he and Whately wished to move on to other things. But according to the ITV spokeswoman Kate Bain, Lewis may still return to television in 2014, either as another series or as a one-off.
