Book editor Susan Ryeland is hired to edit a new Atticus Pünd continuation novel, written by Eliot Crace, grandson of the world's most famous children's author. As Susan works through the manuscript, she starts noticing uncomfortable parallels to a real death in the Crace family two decades earlier — and finds herself pulled into danger all over again. Lesley Manville and Tim McMullan return for the third and final chapter of Anthony Horowitz's Susan Ryeland trilogy, following Magpie Murders and Moonflower Murders.

About the show
Marble Hall Murders is the third and final installment of Anthony Horowitz's Susan Ryeland series, following Magpie Murders (2022) and Moonflower Murders (2024). Like its predecessors, it follows Horowitz's signature format: a present-day murder investigation that mirrors the plot of a fictional detective novel within the story. The TV adaptation relocates the fictional Atticus Pünd mystery to 1955 Corfu, a change from the South of France setting used in Horowitz's original novel. Lesley Manville and Tim McMullan return as Susan Ryeland and Atticus Pünd, joined by Patricia Hodge, Mark Bonnar, Jamie Blackley, and Zubin Varla.
