EAST END:  A place for a soap opera?
LAURA:  Could be a pioneer girl; could leapfrog for a listening exam.
SHARKEY: He advocates teenage kicks.
E  They’re very musical.
WALDA:  Twelfth king, or one of Martin’s women?
HAMA:  A city on the Orontes.  Is he?
EGLANTINE:  She’s fragrant, and Chaucerian.
R  She was a Seventies copper.  Different gender, though.
EORL:  That Crabtree!  He’s a rugby player!
Exactement.  Not a bad song, actually.  Feargal Sharkey did some solo stuff after The Undertones, too.  John Peel played Teenage Kicks quite a lot, I think - a DJ who really encouraged and helped new talent.
Rohan ... Fangorn ... I was in roughly the right part of the story. 
 
...
The R that I'm looking for is classed as a sitcom, not a cop show.  It was a sitcom about a police station, with a young PC as the central character.
It was renamed with that copper's nickname from Series 2 onwards.
