Review
David Brown
Were it not swimming dangerously close to the title of a recent ITV1 drama, this moody whodunnit could have been called Before the Flood, as the small Welsh town in which it’s set is bracing itself for a storm that threatens livelihoods and maybe lives themselves. The advancing sea serves also to highlight the fragility of this close-knit but secretive community, something that’s intensified by ex-police detective-turned-teacher Jackie Ellis (Kelly Reilly) discovering the seemingly drowned body of one of her young pupils.
It’s a blow that brings to the surface silty memories of a cold case, one that has especial resonance for Jackie. And the reappearance of her former partner from the force, Eric Bull (Rafe Spall), adds to the feeling of the past breaching the present in strange, unsettling ways.
