Question: is happy valley coming back for season 3

Answer: Yes, Sarah Lancashire initially said that she would not return for a third series, but later confirmed to the news media that she will return. However, no date has been set because Sally Wainwright has previous commitments to work on other projects. ``Sally has told us she wants to write another series, which will be the final one. We don't know when it will happen,'' Sarah Lancashire said in September 2016. Producer Nicola Shindler has confirmed that the series would not be broadcast until 2018 at the earliest.
