Amazon Prime’s ‘Neagley’ Cast Guide (With Photos)

Frances Neagley is finally getting her own spotlight after years as Jack Reacher’s most trusted ally. Maria Sten stars as private investigator Frances Neagley in the new Prime Video action series set in the world of Lee Child’s novels, and the show arrives with a supporting cast built to carry a case that stands entirely on its own.

All eight episodes of ‘Neagley’ will be released on Wednesday, September 16, 2026, exclusively on Prime Video in more than 240 countries and territories worldwide, arriving right after the ‘Reacher’ Season Four finale. Here is a closer look at who plays who in the ‘Reacher’ spinoff.

Maria Sten

Frances Neagley, played by Maria Sten, is essentially the only character besides Reacher himself who has stuck around across every season of ‘Reacher,’ with Reacher inevitably calling her for help whenever he realizes he is in over his head. That recurring role has now become a lead one.

Neagley follows Frances Neagley as the former protégé of Jack Reacher who is now a private investigator in Chicago. When she learns that a beloved friend from her past has been killed in a suspicious accident, she becomes hell-bent on justice.

Using everything she has learned from Jack Reacher and her time as a member of the 110 Special Investigators, Neagley puts herself on a dangerous path to uncover a menacing evil. Unlike prior seasons of ‘Reacher,’ this story is not pulled from an existing Lee Child book.

‘Neagley’ is venturing into completely original territory with a story that is not based on any existing book, a distinction that holds true across both Lee Child and Andrew Child’s published contributions to the franchise. That gives Sten’s character room to grow outside the shadow of the source material.

Alan Ritchson

Reacher himself is not sitting this one out entirely. Ritchson is set to appear in the spinoff as a guest star, reprising his role as Reacher, giving longtime fans a direct thread connecting the two shows.

Ritchson’s involvement makes this a genuine extension of the existing show rather than a disconnected spinoff built around a brand new character. His guest appearance is timed closely with the flagship series.

Prime Video has deliberately positioned ‘Neagley’ right alongside ‘Reacher’ Season 4, with an opening sequence that reunites Sten and Ritchson in Chicago. It sets up the transition from one show to the other without losing the connective tissue between characters.

‘Reacher’ Season Four premiered with three episodes on Wednesday, August 12, 2026, followed by weekly episodes that culminated in the debut of ‘Neagley’. That rollout was designed to hand the audience off from Reacher’s story directly into Neagley’s.

Damon Herriman

The spinoff’s antagonist is played by Damon Herriman, who appears as Lawrence Cole. The cast alongside Sten includes Greyston Holt as Detective Hudson Riley, Adeline Rudolph as Renee Birdwhistle, Jasper Jones as Keno, Matthew Del Negro as Pierce Woodrow, and Damon Herriman as Lawrence Cole.

Early impressions of the character suggest he is meant to unsettle rather than simply menace. Damon Herriman is described as playing what looks like a genuinely unsettling villain opposite Sten’s investigator.

His role gives the season an antagonist built specifically for this story rather than one lifted from a Reacher novel. Since the plot is original, Cole’s motivations and connection to Neagley’s investigation are not something audiences can look up in advance.

That unpredictability is part of what separates this season from the source material driven plots of earlier ‘Reacher’ seasons. Viewers heading into the premiere will be working with the same blank slate as the character herself.

Adeline Rudolph

Adeline Rudolph joins the ensemble as Renee Birdwhistle. Along with Ritchson and Sten, ‘Neagley’ features Damon Herriman, Matthew Del Negro, Adeline Rudolph, Greyston Holt, and Jasper Jones rounding out the main cast.

Birdwhistle’s exact role in the season’s central mystery has not been broken down in detail publicly, but her presence in the promotional materials places her among the core supporting characters. Prime Video first teased the series at a San Diego Comic Con panel before releasing the full trailer, where the ensemble was shown together.

The trailer’s tone has been described in strong terms by the network itself. Prime Video described the official trailer as high octane, matching the tone fans expect from this corner of the Reacher universe.

That framing suggests Rudolph’s character will be embedded in the season’s action sequences rather than kept on the sidelines. Her arc is expected to unfold alongside the other investigators as the season’s central case develops.

Greyston Holt

Greyston Holt rounds out the cast as Detective Hudson Riley, a law enforcement presence working alongside or against Neagley’s private investigation. The cast also includes Greyston Holt as Detective Hudson Riley in the confirmed lineup for the season.

The series is created for television by co-showrunners and executive producers Nick Santora and Nicholas Wootton and produced by Amazon MGM Studios, Skydance Television, and CBS Studios, the team responsible for shaping how characters like Riley fit into the larger investigation.

A second season of ‘Neagley’ has not been confirmed yet, though it is considered likely given how the current press has consistently referred to this batch of episodes as Season 1. If that happens, Holt’s character could carry over into future installments.

For now, Detective Riley is positioned as part of the ensemble supporting Sten’s Neagley through her first solo case. With the full cast set and the premiere date locked, the only thing left is to see how these characters play off each other once the season actually airs.
