BBC One thriller The Pact has been another hit of a drama for the nation's broadcaster gripping viewers every Monday night for the last four weeks.
Set in Wales, The Pact is a murder mystery about four friends and colleagues after their boss is found dead.
With any hit show, fans always want more and lead actress Rakie Ayola has teased the potential for additional seasons of the show.
"If you think about it, you could have a series where the world blows up and there's nothing left except a blade of grass and if someone wanted to get 17 years out of it, they could," she told Digital Spy, before adding, "But as it is... it's so beautifully formed. So you never know. We shouldn't jinx it. These six episodes are worth investing in because they are fantastic and there really is a story that goes from A to Z."
Teasingly, Rakie also stated, "We might be here in 20 years talking about it. Who knows?"

Will there be a second season of The Pact on BBC One?
A second season of the show has not been commissioned just yet, with the first series having only recently debuted on BBC One, so it's not yet possible to predict when a second season might land, or if there will even be one.
The first run ends pretty conclusively, but that doesn't mean there's no chance of a second season, at least not according to creator Pete McTighe.
Speaking to RadioTimes.com ahead of the series debut, he said: "It was important to me that there was a really clear satisfying conclusion to the show.
"I think a lot of shows nowadays they kind of hedge their bets a little bit because they obviously want a second season, and we want a second season too but it’s important to me that actually, this story does have the closure that I think audiences want.
"So there’s definitely more stories left in The Pact if we’re lucky enough to get a second series, and I’d love to do it."

Who could star in a second season?
If McTighe does choose to tell a new story with the same characters, we can expect to see more of The Pact cast including Laura Fraser, Jason Hughes, Eiry Thomas, Rakie Ayola, Helen Gwynn and Abbie Hern, provided the actors were all keen to reprise their roles.
Julie Hesmondhalgh's character Nancy ended the season just starting a presumably lengthy prison sentence, so it's unlikely we would see her again, while the characters played by Aneurin Barnard and Eddie Marsan both died during the events of the first run.
It's likely that whatever approach is taken a second season would also see some new characters introduced, and should there be any developments we'll update this page.
What could The Pact season 2 cover?
At this stage, it's impossible to make too many predictions about the plot of a second series – especially given we don't even know if it will get the go ahead.
If a second season does get the green light, it's possible that McTighe could opt to tell a different story with the same set of characters, or shift it up entirely and introduce a new batch of characters – essentially turning the Pact into an anthology series along the lines of The Syndicate.
One thing that we know for sure is that any second season certainly won't involve the case of the murder of Jack Evans, with that storyline having been tied up at the end of the season one finale.
