As addictive as it is ludicrous, The Masked Singer appeals to pretty much everyone to shout "take it off!" at their screen on a Saturday evening.

Last week, Katherine Ryan was the surprise celebrity behind Pigeon and previous unmaskings have included Lulu, Chris Kamara, and Martin and Shirlie Kemp.

It's rare these days that appointment-to-view TV exists at all, never mind having such a universal appeal as Happy Valley does.

But Sally Wainwright's gritty drama about Sergeant Catherine Cawood (Sarah Lancashire) battling Yorkshire's drug problem as well as her own personal animosity with criminal Tommy Lee Royce (James Norton) has got the nation speculating over what the finale might be.

Apparently, multiple endings have been filmed for the last ever episode, set to run at 10 minutes longer than usual to cover the many loose ends - but whatever Catherine and Tommy's fates, you won't want to risk spoilers by missing this one.
