Sky has officially greenlit a second season of the crime drama Under Salt Marsh, following the strong performance of the show's debut. Creator Claire Oakley will return to spearhead the narrative, with lead actor Rafe Spall reprising his role as Detective Eric Bull. Production for the new six-episode run is scheduled to begin in Scotland in 2027.
Production and Creative Team
Little Door Productions will produce the sophomore season in association with Sky Studios. Oakley leads a writing room that also includes In-Sook Chappell, Jonathan Harbottle, and Scott Graham. The production moves away from the coastal setting of the first run, relocating filming to a remote Scottish mining village where the plot unfolds.
Narrative Direction
The second season follows Detective Eric Bull as he relocates to the Scottish Highlands. In his new posting, he investigates a murder directly linked to unresolved events from his past. This storyline shifts the tonal and geographical focus of the series while maintaining the central protagonist.
Audience Reception and Platform Rollout
The renewal follows strong viewership metrics for the first season, which premiered in January and reached a 28-day audience of 2.5 million viewers across platforms, establishing it as Sky's leading entertainment title of the year.
The upcoming six episodes will air on Sky and the streaming service Now in the UK, Ireland, and Italy after production wraps. NBCUniversal Global TV Distribution manages international sales for the property outside these territories.
This remarkable ratings performance proved instrumental in securing the swift greenlight from network executives, cementing the psychological thriller as a cornerstone of the broadcaster's scripted portfolio. As the creative team prepares to transition from the writers' room to active principal photography, anticipation builds around how the expanded collaborative writing structure will influence the pacing and depth of the overarching mystery. By bringing together diverse narrative voices under Oakley's continued creative vision, the production aims to elevate the psychological stakes for Spall's beleaguered detective. Fans of the inaugural run can expect a meticulous narrative construction that balances the claustrophobic atmosphere of the isolated mining community with the sweeping, rugged terrain of the Scottish landscape.
Ultimately, this strategic expansion positions the franchise for long-term international success. With NBCUniversal Global TV Distribution steering overseas sales, the psychological drama is poised to captivate a broader global audience when it finally lands on screens following its 2027 production schedule.
