The murderer in Corfu claims another victim. Back in reality, Eliot's condition worsens, and Susan unexpectedly finds herself a suspect in a murder case.

Marble Hall Murders reunites audiences with the clever meta world first brought to life in Magpie Murders (2022) and Moonflower Murders (2024).

In Marble Hall Murders, editor Susan Ryeland is pulled into a new literary puzzle when she’s hired to work on a continuation novel in the Atticus Pünd series, penned by a troubled young writer. But when the assignment draws her into another very real murder case, Susan soon finds herself cast as a suspect. Meanwhile, within the world of the novel, the enigmatic detective Atticus Pünd travels to the Isle of Corfu where he becomes embroiled in the murder of Lady Margaret Chalfont.
