01
Magpie Murders
Suffolk village textures meet Dublin doubles in the adaptation that introduces editor Susan Ryeland and fictional detective Atticus Pünd.
Three books, three adaptations
The mysteries
Each story contains a contemporary Susan Ryeland investigation and an Atticus Pünd mystery within it—two eras, two visual worlds and twice the location detective work.
02
Moonflower Murders
Crete’s light frames Susan’s new life, while the investigation leads back to an English hotel recreated through Irish locations.
03
Marble Hall Murders
The final adaptation expands the trail through London, Dublin and Corfu, including atmospheric island villages and mansion settings.

The mysteries within the mysteries
Case files
Each adaptation combines Susan’s contemporary investigation with a manuscript case solved by Atticus Pünd. Reveals stay closed until requested.
Magpie Murders
A missing final chapter and the death of Alan Conway force Susan to read his last Atticus Pünd mystery as evidence.
- Susan Ryeland searches for Conway’s missing chapter.
- Atticus Pünd investigates deaths in Saxby-on-Avon.
- Alan Conway has modelled suspects on people in his life.
Television spoilers
The modern and manuscript mysteries converge because Conway embedded personal grudges and real identities in his fiction. The full solution belongs behind the site-wide spoiler control.

- Susan returns from Crete to investigate Cecily MacNeil’s disappearance.
- Frank Parris’s earlier murder is reopened.

Television spoilers

Rights and distribution
Who brings the trilogy to viewers
Distribution is recorded separately from the UK-first broadcast history. A distributor does not guarantee that a title is currently available in every territory.
BBC and BritBox
BBC One dates remain canonical on this guide. Magpie Murders had an earlier UK release on BritBox; that release is shown as secondary history rather than substituted for the BBC date.
PBS Masterpiece
Masterpiece is the principal US broadcast home recorded for the adaptations. PBS premiere dates are kept separate from BBC dates.
Sony Pictures Television
BBC production information identifies Sony Pictures Television as the international distributor for Marble Hall Murders. Territory partners are listed only when an authoritative current source confirms them.
