Just when it looked like Liar was wrapping up and serial rapist Andrew Earlham was headed for prison, the ITV drama delivered one final surprise. [SPOILER ALERT]


In the final moments we saw Andrew Earlham (Ioan Gruffudd) half-submerged in the muddy marshes, his throat slashed and blood on his shirt. So who killed him?

ITV has confirmed that the Harry and Jack Williams' psychological thriller will return for a second series, with both Joanne Froggatt and Ioan Gruffudd reprising their roles for a final run focusing on who killed the serial rapist.

“Liar has gripped the nation over the last six weeks and we’re delighted both Joanne and Ioan will return to play Laura and Andrew," said ITV's head of drama, Polly Hill. "Jack and Harry Williams are incredible storytellers and part two of Liar will have the audience equally gripped, as we find out who killed Andrew Earlham."
Harry and Jack Williams added: “We always hoped this story would return for its final chapter, and we can’t wait to be reunited with the brilliant Joanne and Ioan.”
