A Good Girl’s Guide to Murder Summary: The Full Investigation

⚠️ SPOILER WARNING: This section recounts the complete plot, including the ending and all major revelations.

The story begins in Little Kilton, a small English town still haunted by the 2012 disappearance of seventeen-year-old Andie Bell.

Police ruled that Andie was murdered by her boyfriend, Sal Singh, who then took his own life.

The case was closed.

But five years later, high school senior Pippa Fitz-Amobi isn’t convinced.

For her Extended Project Qualification, Pip chooses to investigate the media’s influence on the case. Her real goal is to prove Sal’s innocence. She approaches Sal’s younger brother, Ravi Singh, who agrees to help her.

Together, they start pulling at the threads of the official story. The timeline doesn’t hold. Witness statements conflict. And the town’s collective memory of Andie as a perfect victim begins to crumble.

Pip discovers that Andie Bell led a double life. She sold drugs—including Rohypnol—at parties dubbed “calamity” events. She blackmailed classmates.

She was secretly meeting an older man at the Ivy House Hotel.

As Pip builds her “murder map,” several suspects emerge. Max Hastings bought drugs from Andie. Howie Bowers supplied her. Nat da Silva sent her a death threat after years of bullying. And the “Secret Older Guy” remains unidentified.

The investigation turns dangerous when Pip receives anonymous threats warning her to stop. Then her dog, Barney, is kidnapped and killed. Devastated but determined, Pip pushes forward and uncovers a massive conspiracy.

Sal’s closest friends—Naomi Ward, Max Hastings, Jake Lawrence, and Millie Simpson—had lied about his alibi. They were being blackmailed by someone who knew about their involvement in a hit-and-run accident on New Year’s Eve 2011.

Pip finds photographic proof on a secret Facebook profile: Sal was with his friends until after midnight on the night Andie disappeared. He could not have killed her.

The blackmailer, Pip realizes, is her own history teacher—Elliot Ward, the father of her best friend Cara. Pip tracks him to an old house where she discovers he’s been holding a young woman captive in a hidden loft.

Elliot confesses. He was Andie’s “Secret Older Guy.” On the night she vanished, they argued, and Andie hit her head. Believing he had killed her, Elliot murdered Sal and staged his suicide to protect himself and his daughters.

But Andie hadn’t died that night. She wandered away, disoriented. Months later, Elliot found a vulnerable young woman he mistook for Andie and imprisoned her to keep his secret. The captive is actually Isla Jordan, a missing person with a learning disability.

Elliot is arrested. The town is stunned. Yet one question remains: where is the real Andie Bell?

Pip pieces together the final clues and confronts Becca Bell, Andie’s younger sister. Becca reveals the truth. Andie came home that night injured from her encounter with Elliot.

Becca, who had been drugged and sexually assaulted by Max Hastings—using drugs Andie provided—confronted her sister.

Andie was cruel in response. During their struggle, Andie became sick and began to choke on her own vomit. Becca watched and did nothing. She let her sister die.

Becca then hid Andie’s body in a septic tank at an abandoned farmhouse and ditched her car near Howie Bowers’ property to frame the drug dealer.

When Pip uncovers the truth, Becca attempts to drug and kill her. Ravi and Pip’s father rescue her at the last moment. Three months later, Pip presents her completed project to a packed school hall, publicly clearing Sal Singh’s name.

Elliot Ward faces charges for murder and kidnapping.

Becca Bell is charged for her role in Andie’s death. Max Hastings and Howie Bowers face criminal charges for their separate crimes. Justice, long delayed, finally arrives in Little Kilton.
