Filming begins on the second series of Liar. Who killed Andrew Earlham?

The second series of ITV and Sundance TV’s award-winning six-part thriller Liar, written by Harry and Jack Williams, returns.

9.1m viewers were left reeling at the discovery of Andrew Earlham’s murdered body at the climax of season 1.  Series 2 picks up three weeks after an arrest warrant was issued for Andrew Earlham for the sexual assault of 19 women.  When Andrew’s body is found in the Kent marshes, Detective Renton alongside DS Rory Maxwell are tasked with uncovering clues about Andrew’s past and unpacking the events of the three crucial weeks leading up to his murder.

Joining Joanne Froggatt and Ioan Gruffudd for this final chapter are a number of new characters including Katherine Kelly (Cheat, Mr Selfridge, The Night Manager) as DI Karen Renton, Howard Charles (The Widow, Musketeers) as Carl Peterson and Amy Nuttall (Downton Abbey, My Fair Lady) as Winnie Peterson.

Harry & Jack Williams commented:
“It has been a joy returning to Liar and our reunion with Joanne and Ioan. Equally we are thrilled to have Katherine Kelly on board as DI Renton after her stellar performance in Cheat.”

Liar is commissioned for ITV by Head of Drama, Polly Hill. Commented Polly Hill:
“We’re delighted both Joanne and Ioan are returning to Liar as Laura and Andrew with Katherine Kelly joining the cast as DI Karen Renton.  We’re sure audiences will once again be gripped by the story as Harry and Jack Williams keep you guessing over who killed Andrew.”

“We are thrilled to be working once again with our partners at ITV, Harry and Jack Williams and this exceptionally talented cast on a thrilling new season that will dive deeper into the complicated relationship between Laura and Andrew and the mystery surrounding his death,” said Jan Diedrichsen, Executive Director, SundanceTV and Sundance Now.
