and Lewis become a couple during the seventh (US sixth) season. Rebecca Front as Chief Superintendent Jean Innocent (2006–2014): She is the senior officer supervising Lewis and Hathaway. When Lewis returned from his overseas secondment, Innocent was not convinced that he would be of value, but he proved himself to her on his first case. Innocent is frequently at odds with Lewis over his investigation style. In Series 9, it is revealed that she has gone to work for Suffolk Constabulary. Angela Griffin as Detective Sergeant Elizabeth "Lizzie" Maddox (2014–2015): She becomes Hathaway's DS, following his promotion to detective inspector. Steve Toussaint as Chief Superintendent Joseph Moody (2015): He arrives at Oxfordshire Police as the new chief superintendent, replacing Innocent. He soon clashes with Lewis over the latter's more traditional approach to detective work. Production Colin Dexter, the author of the Inspector Morse novels, makes a very brief cameo appearance in several episodes, including one as a porter at Wadham College. The episode scripts follow Dexter's approach, but each of them is credited to one of several other writers including, most frequently, Russell Lewis, Alan Plater, and Stephen Churchett. The music for the series was composed by Barrington Pheloung, who created the music for the original Inspector Morse series. Following the broadcast of a pilot in 2006, the show's first series was commissioned by ITV, consisting of three episodes that were broadcast between February and March 2007. Following this, further series were commissioned, each with four episodes—the second series was broadcast in 2008 from 24 February to 16 March, the third series in 2009 from 22 March to 12 April, the fourth series was aired in 2010 throughout May, the fifth series was aired throughout April during 2011, and the sixth series was broadcast in 2012 from 16 May to 6 June. During May of that same year, after the show was renewed for a seventh series, Fox made a statement it would be the show's last, as both he and Whately wished to move on to other things. The seventh series was broadcast during 2013 from 7 January to 11 February, and consisted of three two-part stories. On 10 February 2014, an official announcement was made that the show was to return, with all four original main cast members coming back to do another series. The eighth series consisted of three two-part episodes, with shooting beginning in March 2014.
