Beyond Paradise most recently aired during Christmas 2025, for its special festive episode.
The installment followed Humphrey and the team trying to figure out the identity of a man with dementia who has a photo of Humphrey, claiming that he knows him.
The BBC's synopsis states: 'An elderly man living with dementia turns up on the police station steps, clutching only a photograph of Humphrey.
'He's searching for his sister, Louise, and believes that Humphrey is his last hope. But with precious few clues to her whereabouts, the team must work against the clock to unravel the mysteries of his past.
'Just as they dive into the search, the station is rocked by another call. There's been a break-in at a local wine bar, where the team celebrated their Christmas party just hours before. On top of this, Kelby is called to an unusual emergency: a man hopelessly trapped inside a snowman suit after his head was glued on as a prank.
'As the clock ticks down, could the snowman hold a vital clue to solving another festive mystery?
'With an influx of unexpected visitors, a slew of holiday crimes to crack and a heartwarming reunion on the line, can the team juggle it all and still be ready for a life-changing reveal?'
The episode left many feeling very emotional and many took to X, formerly known as Twitter, to share their thoughts.

'Beyond Paradise doesn't get the credit it deserves. Brilliantly written, brilliantly cast, brilliantly acted.'

'What a great episode the Christmas special was.'

Talking about the episode, actor Kris told the Beeb: 'It's such a personal story for Humphrey. A man turns up on his doorstep with a picture and we're not sure why, but it soon becomes a deeply touching story.
'I find it becomes especially personal because of the eventual reason as to why he has Humphrey's photograph - it's a very Christmassy story that warms the cockles.'
Beyond Paradise airs on BBC One and iPlayer.
