Between the Lines: Five women. One killer. And a dead friend who left the answer hidden in plain sight.

They spent a year studying how to get away with murder... now, one of them is putting the theory into practice.

Nora Gallagher prefers the quiet of her workshop, where broken things stay fixed and the past stays buried. But when her close friend Pam is found dead, the peace of Cranthorpe village is shattered. The crime scene is chillingly familiar - not because Nora has seen it in the news, but because she just read about it in her weekly book club.

The murder is a carbon copy of the case they discussed over wine and shortbread just days before.

While the police focus on the grieving husband, Nora discovers a secret Pam left specifically for her: a coded clue hidden in a glasses case that points to a betrayal decades in the making. Alongside a cynical young journalist and a sharp-eyed archivist, Nora begins to pull at a thread that connects their reading list to a string of local secrets. They soon realize the books weren't just suggestions - they were a curriculum for the perfect crime.

In a club where everyone is an expert on forensic errors and investigative failures, Nora is no longer just a reader. She’s a target.

The deeper she digs, the clearer it becomes that their curated "Murder Club" has a killer at the head of the table. Someone has been using the group to field-test a map for murder, and they’ve spent eight months ensuring the ending remains unwritten. As the line between fiction and reality vanishes, Nora realizes that the person she’s trusted for years is the one most desperate to close the book on her - for good.
