The new year on Netflix began with the release of Run Away, the latest adaptation of a novel by Harlan Coben. The eight-part series follows Simon Greene, a father whose life shatters when his daughter Paige disappears into a world of drugs. While the core mystery of a parent’s desperate search remains faithful to the 2019 book, the show’s creators have made several significant changes for the screen, expanding roles, inventing new characters, and adding deeper backstories to heighten the drama.
For fans of the book, the series offers a familiar yet fresh experience. The shocking final twistโwhere Simon learns his wife, Ingrid, unknowingly killed her own sonโis intact from the source material. However, the journey to that revelation is different, with the Netflix version introducing new layers of personal intrigue and moral complexity.
How Key Characters Were Transformed for Television
One of the most notable changes involves the character of Lou, the tech expert who assists private investigator Elena Ravenscroft. In Harlan Coben’s novel, Lou is a man with a relatively minor role in the story. For the series, the character was completely reinvented. Lou is now a woman, played by Annette Badland, and she is specifically Elena’s mother-in-law. This change adds a personal dimension to their professional relationship and integrates Lou more deeply into the emotional subplot surrounding Elena’s late husband.
The series also introduces characters who do not exist in the original book. A major addition is Maria, a woman Elena secretly investigates. Elena discovers that Maria is the secret daughter of her late husband, a revelation that leads to high-stakes drama, including a break-in and an arrest. This entire storyline was created for the television adaptation to flesh out Elena’s personal motivations and grief.
Another new character is Doctor Jay Stanfield, a colleague and former love interest of Ingrid Greene. In the show, Jay fights to save Ingrid’s life after she is shot and provides her with a false alibi for the night of the murder. His presence creates tension in Simon and Ingrid’s marriage, leading Simon to suspect an affair and even question the paternity of his children. Jay’s character is absent from the book, where Ingrid’s actions and alibi are handled differently.
Expanded Backstories and Added Violence
The television adaptation gives much more depth to the hired killers, Ash and Dee Dee. While the book mentions their troubled upbringing, the Netflix series shows it in a visceral, added scene. In the show, Ash and Dee Dee visit their former foster mother, Mrs. O’Hara, and confront her about the physical abuse she inflicted on them as children, which involved burning them with an iron. The tense visit turns deadly, and they murder her. This violent side-quest does not happen in the novel, serving to make the assassins’ characters more complex and their bond more tragic.
The central mystery of who killed the drug dealer Aaron Corval has the same answer in both versions: Ingrid Greene. Desperate to free her daughter Paige from Aaron’s grip, Ingrid murders him and stages the scene to look like a gang-related crime. The fact that Paige knows her mother is the killer and that Simon eventually uncovers the truth are also key plot points faithfully adapted from the book.

The most devastating revelation forms the climax of both the book and the series. After the immediate chaos has settledโwith Ingrid awake from her coma and Paige returning from rehabโSimon uncovers a final, horrific secret. He learns that Ingrid, in her youth, was a member of a cult called The Shining Truth (referred to as The Shining Haven in the series). She became pregnant and gave birth to a son but was told the baby was stillborn. In reality, the cult leader had the child illegally put up for adoption.
That child grew up to be Aaron Corval. Paige and Aaron discovered they were half-siblings through a DNA genealogy website. This means Ingrid, in her mission to protect her daughter, actually killed her own long-lost son. The story ends with Simon and Paige agreeing to carry this unbearable secret, vowing never to tell Ingrid the truth to protect her from the unimaginable pain.
โThis one has more twists and turns than any. Episode 8 especiallyโฆ It has to be emotional, it had to be a twist that would not only make you gasp out loud but hits you in the heart a little bit,โ said Harlan Coben about the finale’s revelations.
The series concludes on this moment of quiet tragedy, with the family together but forever burdened by what they know. All eight episodes of Run Away, starring James Nesbitt, Minnie Driver, and Ruth Jones, are available to stream globally on Netflix.
