Joanne Froggatt’s rape drama Liar will return for a new series, ITV has announced.

The tense drama about a teacher (Froggatt) who claimed to have been raped during a date with a surgeon (Ioan Gruffudd) reached its nail-biting climax on Monday, with viewers left reeling at the discovery of Andrew’s dead body.

The new run of the hit show, which will start filming in January 2019, will focus on who killed him.

Froggatt and Gruffudd will both return for the new series, which will again be written by Jack Williams and Harry Williams of Two Brothers Pictures.

Polly Hill, ITV’s head of drama, said: “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.

“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.”

Jack and Harry 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.”
