Right now you can watch Under Salt Marsh in Australia on BINGE and Foxtel Now, and in the UK on Sky Go and Now TV — and it earns its twists rather than manufacturing them. The 1-season run is exactly the right length for what it is doing. A 7/10 rating says what the writing already makes obvious: this one works. Kelly Reilly sets the tone, and the ensemble matches it scene for scene. Available now on BINGE — press play and find out why people keep recommending it.

Part of the current wave of titles people are actually watching, Under Salt Marsh earns its spot. Under Salt Marsh treats its mystery as a means, not an end in itself. Morfa Halen is a tight-knit Welsh town precariously nestled between towering mountains and a fast-encroaching sea that threatens its very existence. As a once-in-a-generation storm begins to gather far out at sea, former detective turned teacher Jackie Ellis discovers the body of her 8-year-old pupil, Cefin, seemingly drowned. The discovery sends shockwaves through the community, reviving the ghost of an unsolved cold case that rocked the town three years prior - the disappearance of Jackie’s niece, Nessa, which cost her career. Kelly Reilly and Rafe Spall lead a cast that never lets the mystery feel thin. It was aired in 2026. What makes Under Salt Marsh hold up is that the resolution matters less than how the characters get there. It delivers reliably on what it promises, which is more than most of its competition manages.

If you cannot walk away from a good mystery, Under Salt Marsh will keep you hooked. Agatha Christie's Marple is the obvious comparison, but Under Salt Marsh earns its own place alongside it. Short enough to finish in a weekend, substantial enough to feel satisfying. Kelly Reilly's performance is the kind that shows up on best-of lists years later. If you have been looking for something to fill the gap left by a recently finished story, this is a reliable answer.

Under Salt Marsh wrapped up in 2026, created by Claire Oakley — and 1 season is available to watch from start to finish.
