The Sky Original crime series Under Salt Marsh has viewers hooked with its moody Welsh setting and a mystery tying two tragic cases together. The show, starring Kelly Reilly and Rafe Spall, continues its weekly rollout, and the next episode is almost here. This is your complete guide to Episode 4, including the official release time, where to watch, and a look at the intense story developments leading up to it.
Fans saw the first two episodes debut on January 30, 2026, with Episode 3 following on February 6. The series follows a weekly release pattern, with new installments arriving every Friday. This schedule means the suspense builds from one week to the next, rather than the entire story dropping at once.
Under Salt Marsh Episode 4 Release Date and Time
Episode 4 of Under Salt Marsh is scheduled for release on Friday, February 13, 2026. The episode will be available to stream on Sky Atlantic and the NOW platform in the UK. For viewers in the United States, Canada, Australia, and other international regions, official release plans have not been confirmed, as the series is a Sky Original exclusive.
Based on the pattern from previous weeks, the episode typically becomes available for streaming at 9:00 PM GMT on its release date.
What to Expect in Under Salt Marsh Episode 4
The series centers on former detective Jackie Ellis (Kelly Reilly), whose career was destroyed by the unsolved disappearance of her niece, Nessa, three years ago. Her quiet life as a teacher is shattered when she discovers the body of her young pupil, Cefin, on the marshes. This brings her estranged ex-partner, Detective Eric Bull (Rafe Spall), back to the fictional town of Morfa Halen to investigate, reopening old wounds.
Early details for Episode 4 promise major emotional and investigative twists. The official description states:
“Jackie struggles after her estranged sister returns and reignites years of guilt and betrayal, while Bull finds himself faced with two cases that are undeniably linked. A confession is made, but he suspects it has been designed to protect someone closer to home, while DNA evidence exposes a devastating truth and both Jackie and Bull must choose between protecting themselves or those they love.”
This suggests the personal stakes for Jackie will skyrocket as family turmoil collides with the criminal investigation. For Detective Bull, a confession in the case may not be what it seems, leading him to question the motives of the tight-knit community. The mention of “devastating truth” from DNA evidence indicates a breakthrough that could change everything for the main characters and the town.
The Story So Far: A Recap of Episodes 1-3
To understand where Episode 4 picks up, here is a quick summary of the key events from the first three episodes of the season:
Episodes 1 & 2 (Released January 30): The series opened with teacher and former detective Jackie Ellis finding the body of her student, Cefin, who appeared to have drowned in a drainage ditch on the salt marshes. Detective Eric Bull arrived to lead the investigation, revealing a strained history with Jackie from the unsolved case of her missing niece, Nessa. Initial clues—a missing pair of blue wellies and evidence Cefin was moved after death—pointed to foul play. The investigation led Jackie and Bull to “the bee man,” an apiarist named Kieran on nearby Spider Island, who had been a suspect in Nessa’s disappearance. The looming threat of a massive storm added pressure to solve the case before evidence was washed away.
Episode 3 (Released February 6): This episode likely delved deeper into the connections between the town’s residents. Prior episodes established that both Nessa and Cefin had drawn a mysterious picture of what looked like an astronaut, which Cefin’s friend called “the bee man”. Bull was also shown to be keeping a significant secret of his own after being recognized by someone from an environmental institute. Jackie’s personal life became more complicated through her interactions with local Dylan Rees, whose alibi was not fully established.
