The Good Daughter on Peacock: Cast, Release Date and Karin Slaughter Book Connection

Karin Slaughter’s bestselling thriller The Good Daughter is officially coming to Peacock and the adaptation now has a confirmed release date, a six-episode format and a cast led by Rose Byrne and Meghann Fahy.

Peacock will premiere The Good Daughter on November 12, 2026. Byrne and Fahy play Samantha and Charlotte Quinn, two estranged sisters whose lives were shattered by a violent attack during childhood. When another horrifying crime occurs in their Georgia hometown, they are forced to confront the secrets and trauma their family never escaped.

The series is directly based on Slaughter’s 2017 standalone novel. Even more encouraging for readers, Slaughter adapted her own book for television and wrote all six episodes.

The Good Daughter on Peacock at a Glance

Peacock has confirmed the premiere date but has not yet clarified in its official announcement whether all six episodes will arrive together or follow a weekly schedule.

What Is The Good Daughter About?

The Good Daughter follows sisters Charlotte “Charlie” Quinn and Samantha “Sam” Quinn, whose family was destroyed by a brutal attack on their home.

Their mother was murdered, the sisters suffered lasting physical and emotional consequences, and their father, controversial defense attorney Rusty Quinn, was left trying to hold the remains of the family together.

Twenty years later, Charlie has followed her father into the legal profession and remained in their hometown of Pikeville. Sam, meanwhile, has built a separate life away from the family.

When another violent attack shocks Pikeville, Charlie becomes the first witness at the scene. The investigation forces her to revisit memories she has spent years trying to suppress. Sam returns home, bringing the estranged sisters together as questions about their childhood and the secrets surrounding their family begin to resurface.

Peacock describes the adaptation as both a suspenseful thriller and an emotional story about family, survival and resilience. The mystery may pull viewers into the series, but the complicated relationship between Charlie, Sam and their father appears to be its emotional center. NBCUniversal’s official announcement confirms that the limited series will consist of six hour-long episodes.

Who Is in the Cast of The Good Daughter?

The series has assembled an impressive cast, with Rose Byrne and Meghann Fahy playing the two Quinn sisters at the center of the story.

Meghann Fahy as Charlotte “Charlie” Quinn

Meghann Fahy plays Charlotte Quinn, the younger sister and a defense attorney who has followed in her father’s footsteps.

Charlie remained in Pikeville after the attack that destroyed her childhood. When she witnesses a new act of violence, the case brings back memories and questions she has tried to bury.

Fahy has become a familiar face to mystery and thriller audiences through projects including The Perfect Couple and Sirens. She also received an Emmy nomination for her performance in the second season of The White Lotus.

Rose Byrne as Samantha “Sam” Quinn

Rose Byrne stars as Samantha Quinn, Charlie’s older sister.

As a child, Sam attempted to protect Charlie during the home invasion and suffered injuries that continued to affect her as an adult. She eventually became a patent lawyer and established a life away from Pikeville, but the new crime draws her back toward her estranged family.

Byrne is also an executive producer on the series. According to the first-look report from Vanity Fair, she worked with a physical therapist while preparing to portray the lasting effects of Samantha’s injuries. The first-look feature also reveals that the production consulted organizations including Brady and RAINN when depicting gun violence and sexual assault.

Brendan Gleeson as Rusty Quinn

Brendan Gleeson plays Rusty Quinn, Charlie and Sam’s father.

Rusty is a defense attorney whose willingness to represent unpopular clients has made him a divisive figure in Pikeville. His professional choices are also connected to the attack that changed his family forever.

The relationship between Rusty and his daughters is essential to the story. Both women must decide what they owe their father—and what being a “good daughter” has already cost them.

The Supporting Cast

The confirmed cast also includes:

• Olivia Williams as Harriet “Gamma” Quinn, Charlie and Sam’s mother
• Audrey Grace Marshall as young Samantha
• Drew Cheek as young Charlotte
• Michael Dorman as Ben
• Harper Steele as Lenore

Peacock’s earlier casting announcement also included Paula Malcomson and Jake McDorman among the series regulars. The platform’s official cast introduction provides a closer look at the ensemble assembled for the adaptation.

Is Peacock’s The Good Daughter Based on a Book?

Yes. The Peacock series is based on Karin Slaughter’s novel The Good Daughter, which was published in 2017.

The novel begins with two masked men entering the Quinn family home. The attack leaves the girls’ mother dead and sends Samantha and Charlotte into the woods at gunpoint. One sister manages to run, while the other is left behind.

Nearly three decades later, Charlie is present when another devastating act of violence occurs in Pikeville. As she becomes involved in the new case, memories of the original attack return and previously hidden details about that night begin to emerge.

Slaughter’s official description of the novel presents it as a mixture of psychological suspense, cold-case mystery, courtroom drama and family tragedy. Those elements appear to have been preserved for Peacock’s version.

Is The Good Daughter Part of the Will Trent Series?

No. The Good Daughter is a standalone Karin Slaughter novel and is not part of the Will Trent or Grant County series.

That means viewers and readers do not have to know anything about Will Trent, Sara Linton or Slaughter’s other recurring characters before starting this story. Charlie, Sam and the Quinn family have their own self-contained storyline.

There is, however, a related digital short titled Last Breath. That story follows Charlie during an earlier case in her career as a defense attorney. It provides additional background about the character, but it is optional and is not required before reading The Good Daughter or watching the Peacock adaptation.

How Closely Will the Peacock Series Follow the Book?

Peacock’s official synopsis follows the central premise of Slaughter’s novel closely: the Quinn sisters survive a childhood attack, Charlie becomes a lawyer and a new crime forces the family to revisit its past.

One already visible change concerns the timeline. The book’s present-day story occurs 28 years after the attack on the Quinn family, while Peacock’s synopsis describes the sisters as having spent the last 20 years trying to rebuild their lives.

The television version may also expand certain characters and relationships to support six hour-long episodes. However, the biggest reason to expect the series to preserve the book’s emotional core is Slaughter’s direct involvement.

Slaughter is not simply receiving an executive-producer credit. She serves as showrunner and wrote every episode, while Steph Green directed the complete limited series. Slaughter reportedly completed the initial six scripts during an intense two-week writing period, giving her unusual control over how her novel was translated for television.

That does not guarantee a scene-for-scene recreation. An author adapting her own work may still change timelines, combine characters or rewrite plot points that function differently on screen. It does suggest that any major alterations will come from someone who understands why the original story resonated with readers.

How Many Episodes Will The Good Daughter Have?

The Good Daughter will have six episodes, with each episode running approximately one hour.

The limited-series structure should give the adaptation more room than a two-hour movie to explore both timelines. The novel gradually reveals what happened to Charlie and Sam as children while also following the new crime in Pikeville.

That structure is particularly important because The Good Daughter is more than a conventional whodunit. Its suspense depends on memory, family resentment and the different ways two sisters remember the same traumatic event.

Why The Good Daughter Could Become Peacock’s Next Major Thriller

The combination of Karin Slaughter, Rose Byrne and Meghann Fahy makes The Good Daughter one of Peacock’s most promising literary adaptations.

Slaughter has already seen several of her books reach television. Her Will Trent novels inspired ABC’s ongoing crime series, while Netflix adapted Pieces of Her into a limited series starring Toni Collette and Bella Heathcote.

The Good Daughter offers something slightly different. The story contains a central mystery, but it is equally concerned with the long-term effects of violence and the relationship between two sisters who survived the same night in very different ways.

The first look suggests that the adaptation will retain the novel’s darker material while keeping its focus on survival rather than treating trauma as a source of spectacle. That approach could help the show appeal to fans of character-driven thrillers such as The Perfect Couple, Sharp Objects and The Better Sister.

When Does The Good Daughter Premiere on Peacock?

The Good Daughter premieres November 12, 2026, exclusively on Peacock in the United States.

The complete limited series will contain six episodes. A full official trailer has not been unveiled at the time of writing, but Peacock has released first-look images featuring Rose Byrne, Meghann Fahy and Brendan Gleeson.

For readers who want to experience the original mystery before the adaptation arrives, The Good Daughter can be read without starting any of Karin Slaughter’s other books.

Final Thoughts

Peacock’s The Good Daughter has the ingredients of a gripping and emotionally complex book adaptation. The cast is excellent, the six-episode format gives the story space to develop, and Karin Slaughter’s role as writer and showrunner should reassure fans worried about the novel losing its identity on screen.

The series may begin with a murder and build around another shocking crime, but the real story is about Charlie and Sam: two sisters trying to understand what happened to them, what they owe their family and whether surviving the past is the same as escaping it.
