What is Marble Hall Murders about?
Eleventh Hour Films and MASTERPIECE
This series sees Manville (The Crown, Phantom Thread) return as Susan Ryeland, a book editor who all too often finds herself involved in baffling murders. Returning to England, she is reluctantly drawn into a new Atticus Pünd mystery, this time written by a new, young writer. “Pünd’s Last Case” is a story set in 1955, in an exotic villa in Corfu, but the identity of a real killer is hidden in the book and once again Susan is going to find herself in grave danger.
McMullan (Patrick Melrose, The Crown) reprises his role as Atticus Pünd, the literary detective who steps out of the books to help Susan unravel the real-life mystery. Who killed Miriam Crace, the most famous children’s author in the world?
Here’s the description for Marble Hall Murders: “In Marble Hall Murders, editor Susan Ryeland is hired to work on a continuation novel of the Atticus Pünd series, written by a troubled young author (Jamie Blackley). When the job leads Susan into another murder case, she unexpectedly finds herself a suspect. In the world of the novel, Atticus Pünd is visiting the island of Corfu when he becomes embroiled in the murder of Lady Margaret Chalfont (Patricia Hodge), whose family he investigates with the assistance of a Greek detective (Zubin Varla).”

Is Marble Hall Murders the final season?
Yes, PBS confirmed that this is the final installment of the series.
“We are beyond thrilled to once again be partnering with Eleventh Hour Films to bring one of Anthony’s brilliant novels to life and to have Lesley and Tim return in their roles,” Masterpiece Head of Scripted Content and Executive Producer Susanne Simpson said in a statement when the third season was announced. “The first two series were incredibly successful for us and we can’t wait for our audience to see Marble Hall Murders.”
Executive producer Jill Green implied it could be the show’s end because there are no more books to adapt from this specific story.
“Anthony has once again brought his unique and original perspective to the world of murder mystery. Marble Hall Murders completes the trilogy and the scripts and lead actors are once again at the top of their game,” Green’s statement said.
