The episode ends on a hopeful note, as Lucille’s husband, Cyril, surprises his wife with an open ticket to Jamaica – news which goes a long way towards lifting her spirits, as she has been aching to see her family amid the growing racial tensions in the UK following Enoch Powell’s hateful ‘Rivers Of Blood’ speech.

“I want to go, but I don’t want to leave,” she tells him, her sense of displacement all too apparent.

“The sooner you get to Jamaica, the sooner you’ll be coming back,” replies Cyril.

Perhaps Lucille might return, then, before the new season is out? We shall have to wait and see.
