There was an amusing scene in the second episode of Strike: The Cuckoo's Calling, on BBC One last night.
Set in a central London pub, it featured Tom Burke, playing private investigator Cormoran Strike, and Holliday Grainger as Strike's "intelligent and resourceful new temp" Robin Ellacott.
Confessing he was a "wee bit pissed", Strike had a cigarette between his lips and was asking "Have you got a light?" when it was gently removed by his assistant who reminded him, in a non-hectoring way, "You can't smoke in here."
To which Strike groaned and replied: "They've ruined pubs. Pubs used to be bloody brilliant."
Strike: The Cuckoo's Calling is based on a book by Robert Galbraith which, as most people now know, is a pseudonym for J K Rowling who is also credited as executive producer on the TV adaptation.
The third and final part is on Sunday. Worth watching, not least for the likeable lead characters.
The real question though is not 'Whodunnit?' but 'Has J K Rowling just revealed her thoughts on the smoking ban?'
