You're probably still getting over the shock of that cliffhanger to Monday night's Apple Tree Yard finale. But don't spend too long chewing it over, because it looks like we could be getting a second series of the BBC One thriller.

The TV hit of the year so far came to a stunning conclusion absolutely no-one saw coming as Emily Watson's sexual assault survivor Yvonne Carmichael took the stand in the trial of the murder of her rapist.

The jury ultimately found Yvonne innocent of conspiring to kill the man who'd raped her - but it didn't end there. Moments later, we realised that Yvonne HAD conspired to murder him - by setting up her boyfriend Mark Costley (Ben Chaplin) to take the fall.

Still, as good an ending as that was, there may be more where that came from. According to The Sun, Apple Tree Yard writer Louise Doughty is planning to pen a follow-up novel to her bestseller the four-part TV series is adapted from.

Reportedly, the sequel could delve deeper into Chaplin's character Costley and explore Yvonne's future after the trial, with the BBC also keen to develop the next novel into a second series.

Digital Spy has reached out to the BBC for comment.

Actor Mark Bonnar, who plays the downtrodden husband of Watson's eminent scientist Yvonne, recently spoke to Digital Spy about how the drama handled Yvonne's harrowing rape scene... and its agonising aftermath.

"I'm struggling to think of another [TV series] that has addressed rape as honestly as this before," he said. "Certainly from me watching it with my wife - it still hit me deep in the solar plexus. It's a very visceral experience as a viewer, and all power to it for that."

The series is available on iTunes now, and DVD & Blu-ray Box Sets are released on February 20.
