LONDON (AP) – The laws of television decree that a show that’s both a critical hit and a ratings success must return to our screens. The laws of crime thrillers say that once you know whodunit, the case is closed.

That’s why some viewers were surprised to learn there would be a season two of the BBC’s murder mystery series “Broadchurch” – and why the cast was initially skeptical, too.

“You want to make sure it’s being faithful to the thing that you love,” said Olivia Colman, who plays detective Ellie Miller alongside David Tennant’s investigator Alec Hardy.

“Most of the cast thought, ‘It was great. I don’t know if I want to do it again.’ And then Chris (Chibnall, the show’s writer) talked us through the idea of the second one. And we all said ‘Oh yeah. OK. Lovely. Count us in.'”

The second episode of season two airs Wednesday on BBC America. The first eight-part series, which ran in Britain in 2013 to huge acclaim, showed how the murder of an 11-year-old boy devastated his family and shook their picturesque seaside town.
