Keeley Hawes has admitted she felt a bit of an outsider filming BBC drama Line Of Duty.
The Ashes To Ashes actress stars in the second series of the hit show as Detective Inspector Lindsay Denton, the latest officer to be investigated by anti-corruption unit AC-12. Keeley admitted joining Martin Compston, Vicky McClure and Adrian Dunbar, who all appeared in the first series together, felt strange, but that suited her character.
She explained: "It was quite odd, because it's quite unusual Line Of Duty, in that you always have a guest lead within the show. So when you go into it it's not like going into a series where you know that you're going to get to know the people and hopefully come back, so you build friendships. I knew as I went into it, that that was going to be me, one series and you're out, like Lennie James was in the first.
"So it's quite an odd feeling because it's a lot of work and you're with everybody a lot of the time, but they already have these relationships that they've built up and it's sort of slotting in.
"Lindsay is a bit of an outsider anyway, so in a way that was quite good. They're all great buddies, which is fantastic, but it worked for me, in that I am an outsider within the show."
And the Spooks star revealed she didn't know if her character was guilty or not when she auditioned for the part.
Keeley revealed: "I had read the first five [episodes] and I went to meet Jed Mercurio who is the writer and creator of the show and I said, 'I've got to know in episode six - Is she guilty? Isn't she guilty?' And he said, 'Um, I don't know yet'!
"So it was brilliant because I read some of the scenes and you don't play anything if you don't know if there's guilt or not."
Line Of Duty returns to BBC Two on February 12.
