Marble Hall Murders arrives Sept 6 @ 9/8c
Fans of Anthony Horowitz’s deliciously intricate, reality-bending mysteries have plenty to look forward to. Marble Hall Murders, the third and final installment of his Susan Ryeland series, returns with Lesley Manville as the book editor prone to entangling herself in real-life murders, alongside Tim McMullan as the fastidious detective who steps out of his fictional world to help her. This time, Ryeland is hired to work on a posthumous continuation of the beloved Atticus Pünd series, set in sun-soaked Corfu. But a gruesome real-time murder begins to eerily mirror the story she’s editing. As the series reaches its conclusion, the biggest mystery may be what fate has in store for Susan Ryeland.
Magpie Murders and Moonflower Murders are the first two installments in this series and full episodes of both stream on PBS Passport.

Maigret | Season 2 premieres Oct 18
We return to contemporary Paris, where Chief Inspector Jules Maigret faces pressure from within his unit to change his methods—just as he and his beloved wife Louise resolve to continue trying for a child. Homeland writer Patrick Harbinson crafts three compelling crimes across Maigret Season 2’s six episodes, with motherhood emerging as a recurring thread. As the cases unfold, Maigret has more reason than ever to question his future—and whether to stay with La Brigade Criminelle or walk away.
New to Maigret? Catch up by streaming Season 1 on PBS Passport.
The Gold | Season 2 premieres Oct 18 @ 10/9c
The Gold Season 2 propulsively picks up where Season 1 left off, with London police accelerating their investigation into the history-making Brink’s-Mat gold heist. [Spoilers ahead if you haven’t seen The Gold Season 1.] The story resumes when DCI Boyce (Hugh Bonneville) and his team realize the original haul was split in two—they’ve only been following half the gold. The hunt now turns to the fate of the other 50 percent. Season 2 reunites Hugh Bonneville with Jack Lowden and Tom Cullen, while welcoming new cast members including Tom Hughes (Victoria), Stephen Campbell Moore (Downton Abbey), and Sam Spruell (Fargo).
