Inspector Morse - Cherubim And Seraphim - Series 6 - Episode 5 [1987]

At the heart of Morse's professional life is his awkward partnership with Detective Sergeant Lewis, the resolutely ordinary, worldly sidekick who manages to keep his boss in an almost permanent state of exasperation while retaining his grudging respect. It's a testament to Kevin Whateley's consistently excellent performance that from such unpromising material Lewis becomes as indispensable to the series as Barrington Pheloung's hypnotic, classic theme music. Morse's investigations do occasionally take him abroad to more exotic locations, but throughout 14 successful years of often gruesome murders, the city of Oxford itself became a central character in these brooding two-hour dramas: creator Colin Dexter stating he finally had to kill Morse off because he was giving Oxford a bad reputation as a dangerous place! -- Piers Ford
