Kate Winslet has said the possibility of a second season of the hit HBO whodunnit Mare of Easttown is the subject of an "ongoing conversation".

The British actress played Detective Mare Sheehan, a gruff, grieving detective investigating a murder in a small Pennsylvania town, in the mini-series. It concluded it's seven episode run in May to widespread acclaim.

Winslet, who was singled out for praise for her convincing and understated performance, previously revealed that she misses playing Mare, and would leap at the chance to portray her again.

The Oscar-winner has now said a potential second run is being discussed.

"I would love to play her again, I absolutely believe there's more chapters to her story," she told Deadline.

"However, just because the story has touched people that doesn’t necessarily mean creatively we can do it again.

"But it doesn’t mean closing doors; we’re opening doors, exploring what’s behind the doors."

The audience reaction to Mare was so positive that HBO signed a three-year exclusive deal with screenwriter Brad Ingelsby, the creator and writer of the series.

Winslet added of the role: "Brad Ingelsby wrote this middle-aged heroine; not many writers have written this before, and I felt so honored and excited when he asked me."

Head of HBO Casey Bloys previously hinted that there may be a second series of Mare Of Easttown despite the original plan of the whodunnit being a once-off.

Bloys told Variety: "If Brad felt like he had a story to tell that felt like it would be at the same level, I think everybody would be open to it.

"Right now, he doesn't have that story. Who knows? We'll have to wait to see if they come up with something they're dying to tell."
