The Pembrokeshire Murders had people absolutely gripped when it landed on ITV on Monday night, telling the story two real life double murders from the 1980s, which were reopened as cold cases back in 2006.
The show, starring Luke Evans as DS Steve Wilkins and Keith Allen as serial killer John Cooper, has had viewers on the edge of their seats ever since it landed on screens.
But it isn't just the two main characters who have got everyone talking, some viewers found themselves distracted by one of the other policemen on the case, too.
Yep, take a closer look and you might well recognise DI Lynne Harries from his role as Owain Hughes in Gavin & Stacey.

Steven appeared as Owain in the BBC comedy back in 2009, and in case you need reminding, Owain was one of Gavin's Welsh work colleagues.
He's famed for one of the most inexplicable jokes of the series, introducing himself and adding: "And before you ask, no I don't," - referring to an in-joke which was funny precisely because nobody ever got it.
Back in Gavin & Stacey, Owain had long wavy tresses and a clean shaven look
But, unsurprisingly, given it is over a decade later, he looked almost unrecognisable as DI Harries, with a shorter haircut and a trimmed beard.

That didn't stop some hard-core fans of the show spotting him, though.
"Watching The Pembrokeshire Murders on ITV. Owain Hughes from Gavin & Stacey is in it and now I can't concentrate... #anddoyou #noidont," one person wrote.
While another penned: "Glad to see Owain Hughes has had a promotions to investigate the Pembrokeshire Murders#gavinandstacey #pembrokeshiremurders".

"S**ting hell, it's Owain Hughes! (And before you ask, no he doesn't) #PembrokeshireMurders," wrote a third.
The ITV crime drama saw 6.3 million tune in for its opening night, making it the biggest opening audience for a new drama on the channel since 2016.
Owain really has landed on his feet since his office job!
