Nicola Walker and Stephen Mangan will return for a third and final series of, it has been announced.
The BBC drama about divorce lawyers will come to an end as one of the lawyers faces the end of her own marriage.
Created and written bywriter Abi Morgan, the series will feature Dee Koppang O'Leary as the lead director, while cast members Annabel Scholey, Fiona Button, Deborah Findlay and Chukwudi Iwuji are all set to reprise their roles.
The show follows the lives of the three Defoe sisters, Hannah (Walker), Nina (Scholey) and Rose (Button) and their mother Ruth (Findlay), after Hannah's marriage to Nathan (Mangan) finally fell apart.
Ten months on, the two lawyers have been respectfully negotiating their separation and seem to have reached an amicable agreement.
But as they divide up the contents of their lives together, Hannah faces what she is about to lose and a shocking revelation changes the stakes, leaving their dream of achieving a "good divorce" in tatters.
Walker added: "I can't wait to be back in the Defoe family, we are all looking forward to the journey Abi has planned for us. I don't know if Hannah will cling to the wreckage or walk away, but I do know it's going to be a fantastic ride."
The series, produced by production company Sister, is due to start filming later this year.
