All Her Fault Is the Best Upcoming Mystery Series of 2025

All Her Fault is an eight-episode mystery-thriller miniseries that premiered on the streaming platform Peacock on November 6, 2025. Based on the 2021 bestselling novel by Andrea Mara, the series is one of Peacock’s major original releases for the fall-season slate.

Premise & Plot Overview

At its core, All Her Fault follows Marissa Irvine (portrayed by Sarah Snook), a high-powered professional and mother whose life takes a terrifying turn when she arrives at what should be a routine playdate pickup—and is told her son doesn’t exist. According to the official synopsis:

“Marissa arrived to collect her young son Milo from his first playdate, but the woman who answered the door isn’t a mother she recognises. She doesn’t have Milo and has never heard of him.” 

This moment sets off an intense chain of events: the disappearance of the child, the surface-scraping of buried secrets, the fraying of relationships and trust. Although the show is built on a fictional foundation, the author of the original novel reveals that parts of the inspiration came from a real-life “what-if” moment when she found herself at the wrong house picking up her daughter—a moment of panic that triggered the big question: What if there were no answer? 

The first season comprises eight episodes, each with a runtime of roughly 46–56 minutes. Importantly, it is structured as a limited series—streamed all at once on its premiere date—though there has been talk of possible future expansions.

Cast & Creative Team

The series features a strong ensemble cast:

• Sarah Snook as Marissa Irvine
• Dakota Fanning as Jenny Kaminski
• Jake Lacy as Peter Irvine
• Sophia Lillis, Michael Peña, Abby Elliott, and Jay Ellis in significant supporting roles.
  On the creative front: the series is adapted by Megan Gallagher from Andrea Mara’s novel, with Mara also serving as an associate producer. The production companies include Carnival Films and Universal International Studios.

Production & Release

Although set in the Chicago suburb context, filming took place in Melbourne, Australia, which gave the production both flexibility and visual polish. The miniseries was shot in 2024 and finished in time for its November 2025 premiere. All eight episodes were made available at once, encouraging binge-watching from the drop date.

Themes & Tone

All Her Fault explores multiple themes: the anxiety of modern parenthood, the fragility of trust, the pressures on working mothers, and the dark undercurrents lurking beneath suburban normality. Critics highlight the show’s layered depiction of maternal guilt and societal expectations placed on women — especially those juggling professional ambitions and family life. The tone is suspenseful, tense, occasionally melodramatic — designed to keep viewers hooked with twists and reveals.

This tv show is coming on Peacock TV, if you are in Mexico so you cannot access  Peacock TV in Mexico because Peacock streaming is ban in Mexico.

What to Expect

If you decide to watch:

• Be prepared for a strong performance from Sarah Snook, who anchors the series with emotional intensity.
• The pacing delivers early shock (the missing child scenario) and then settles into an “unmasking” rhythm of secrets, alliances, betrayals.
• The story is as much about the relationships (between mothers, between spouses) as it is about the mystery.
• While it has many genre thriller elements (kidnapping, hidden identities, unexpected connections), the production tries to weave in commentary on gender roles, parenting, and social image.

Reception

Early reviews are mixed-to-positive. Some critics praise the performances (particularly Snook and Fanning) and the underlying themes about motherhood and trust. Others feel the plotting sometimes leans on familiar thriller tropes and that the narrative occasionally becomes uneven. Overall, if you enjoy domestic thrillers, this is a solid addition.
On aggregate sites, the series holds decent ratings for its category.

Why It’s Worth Watching

• It offers a “what if” scenario that taps into a universal parental fear, which gives the mystery an emotional punch.
• The cast is high calibre, bringing a level of craft that elevates the material beyond straightforward suspense.
• The production values (setting, cinematography, pacing) reflect streaming-era expectations of premium television.
• Thematically, the show gives more than just surface thrills: it prompts reflection about identity (who we are as parents), accountability (who is at fault when something goes wrong), and the hidden lives people lead.
• Because all episodes are available, it’s perfect for a weekend binge—once you start, the momentum carries you through.

Audience Fit

If you like shows such as Big Little Lies, Gone Girl, or earlier “suburban thriller” types, All Her Fault will likely appeal. It will especially resonate if you’re interested in women’s perspectives in thriller settings — how the expectations around motherhood and career collide under pressure. On the flip side, if you prefer very tight, ultra-realistic thrillers with minimal melodrama, this might feel slightly more heightened.

Final Thoughts

All Her Fault is a compelling addition to Peacock’s original roster, offering both entertainment and some deeper thematic threads. While it may not reinvent the genre, it brings together a strong cast, a provocative premise, and the kind of binge-friendly format that streaming audiences respond to. For anyone curious about a twisty domestic thriller with emotional stakes, this is worth your time.
