British television marks the end of an era on 12 March. The Inspector Morse franchise finally comes to an end after close to four decades on screen. The last Endeavour on ITV is the finale after 102 films concerning the Oxford detective.

Inspector Morse, starring John Thaw as the eponymous policeman, has been a staple of ITV’s drama offering since the late 1980s. At its peak, up to 18 million people tuned in to watch the sullen sleuth on Sunday nights. In 2018, Radio Times readers voted it “the greatest crime drama of all time”.

Based on the first two acclaimed novels by Peter James called Dead Simple and Looking Good Dead, the two films star Jon Simm (Doctor Who) as Roy Grace, the tenacious Brighton based Detective Superintendent.

Lewis said: “Each story is a fantastic, hair-raising, twisting, switch-back of a roller-coaster ride that grips the reader from first to last, and the opportunity to translate that best-selling magic to television is like all one’s Christmases and birthdays come at once.”
