The drama is created and written by Mike Bartlett and produced by Drama Republic for BBC iPlayer and BBC One.
What is the storyline for Doctor Foster series 3?
The new series takes place ten years after Gemma discovered Simon's affair and carried out her revenge.
At the time, the fallout proved devastating when her 15 year old son Tom disappeared.
In series three, Gemma remains a GP living in the same house but is preparing for a fresh start after meeting someone new and planning to marry.
As the wedding approaches and loved ones gather, past secrets begin to resurface and threaten both her happiness and her reputation.
Gemma must fight to protect those she loves while uncovering who is intent on hurting her.
What has Suranne Jones said about returning to Doctor Foster?
On returning to the role, Jones said: "When I got the call to ask if I wanted to return as Gemma Foster, I knew the time was right. We needed space from the first two series, and we needed Tom – Gemma and Simon's runaway son – to return as an adult with questions.
"For me, this time around it's about accountability and questioning – 'can we ever truly sever ties with our past and the damage or traumas that haunt us, so we can fully move forward?'
"Gemma and Simon have so much to unpick! It's been an exciting time working with the brilliant Mike Bartlett again, and the team at Drama Republic, on the scripts and now I can't wait to start filming."
Why is Doctor Foster returning now?
Writer Bartlett said: "I always hoped that we'd get to tell the final part of Gemma's story – which is about a woman seeking justice in an unfair world.
"That feels as relevant now as when Gemma first found a blonde hair on the scarf.
"It's been a joy to team up once again with the hugely talented Drama Republic, the now very grown-up and brilliant Tom Taylor, the inimitable Bertie Carvel and of course, the incomparable Suranne Jones, to tell the final chapter of this story and revisit Parminster – where it turns out there's still secrets, betrayals, vengeance and perhaps one last dinner party…"
Executive producers Roanna Benn and Jude Liknaitzky said they were excited to bring the finale to screen and described the scripts as thrilling and gripping.
BBC Drama director Lindsay Salt said: "It's a privilege to welcome Doctor Foster back to the BBC after almost a decade away.
"The extent to which the first two series gripped the nation is a credit to Mike's writing, the talented team at Drama Republic and our magnificent cast – and now we're ready do it one more time in this epic final chapter. Bring it on!"
How successful was Doctor Foster previously?
The drama became a UK ratings hit when it aired in 2015 and 2017, with nearly 10 million viewers tuning in for the series two finale.
It also won National Television Awards for both series, while Jones received a BAFTA for her performance.
The third series will be filmed in and around Hertfordshire, with global sales handled by BBC Studios.
