How To Get Away With Murder will come to an end after the sixth series, it has been announced.

The US drama, which stars Oscar-winning actress Viola Davis as defence law professor Annalise Keating, debuted in 2014.

Announcing the news, the show’s writer and creator, Pete Nowalk, wrote on Twitter: “Deciding to end this series was a brutal decision, but ultimately the story tells you what to do – as it did here.

“For me, Annalise Keating’s journey has always had a clear ending. Knowing I have 15 episodes left to finish her story, and the chance to give all the characters their own killer endings, is a gift rarely given to a network series creator.

“I’m grateful to ABC for the opportunity and creative freedom. I am also beyond thankful to the brilliant cast, writers and crew for dedicating themselves to this show for the last six years.

“HTGAWM only exists because of your loyalty and enthusiasm. I can’t wait for you all to see how it ends. Buckle up.”

Viola, who won an Emmy for her role in 2015, described working on the show as “one of the greatest rides of my life”.

Posting a short trailer for the programme on Instagram, she added: “Here’s to the final, extraordinary curtain call.”

The show’s producer Shonda Rhimes, who is also responsible for Grey’s Anatomy and Scandal, said: “#HTGAWM has brought us six years of twists & turns.”

“Thank you to the cast, crew, and writers for your dedication and passion,” she continued on Twitter.

“Thank you to the fans who have watched every Thursday since the beginning.

“Finally, thank you, @petenowalk. Working with you has been a true pleasure.”

She added: “This might be the last season, but there’s still so much to cover. Get ready for a wild ride.”

Since debuting as Annalise five years ago, Viola has won numerous awards, including the Emmy, a Screen Actors Guild prize and a People’s Choice award. 

She’s also been nominated for a Golden Globe.
