The British actress has said that it is highly unlikely the BBC drama will return, following reports back in May that a final episode was in the works.
However, Garai - who played Bel Rowley in the series - said that no official plans have been made to bring it back.
"I think there's absolutely no chance that it's going to happen," she told Radio Times.
"I mean, of course I would do it again but I just feel bad because there was all this press coming out saying maybe there's going to be a one-off special.
"I don't think they're going to do that because it was quite a public axing and I think for the BBC to make a decision like that and then go back on it, I don't think that would happen."
