Manville and McMullan are set to return in addition to Rebecca Gatward, who will direct. In a statement, Horowitz said, “I’m so happy to bring the team back—stars, director, producers, and crew—for a third installment of what has been a fantastically successful TV series.

The BBC has acquired Marble Hall Murders, an adaptation of the third and final instalment in best-selling novelist Anthony Horowitz's Susan Ryeland series. Marble Hall Murders serves as a follow-up from the acclaimed Moonflower Murders and Magpie Murders, with their TV adaptations averaging 4.9m viewers across the series.

Expected to commence production in March with filming locations spanning Dublin, Corfu, and London, Marble Hall Murders will welcome back Lesley Manville and Tim McMullan to reprise their intriguing roles. Helming the project once more are director Rebecca Gatward and producer Suzanne McAuley.
