ENDEAVOUR 9 p.m. on PBS. A prequel to the “Inspector Morse” series, this detective drama follows a young Inspector Endeavour Morse (based on the character from Colin Dexter’s novels), whose tastes for opera, crossword puzzles and poetry make him a beneficial anomaly for the Oxford City Police in the 1960s. In the Season 6 finale, Morse (sporting a stylish mustache) investigates the aftermath of a deadly tower block collapse, which may be connected to a fatal stabbing at a local library.
