Keeping Faith (2017)

Faith Howells is on maternity leave with her third child when her husband, who is also her partner at the family law firm, goes missing. As she goes back to work to keep things afloat, she learns how little she knew about him, and the small Welsh town around her has opinions about all of it. Eve Myles carries it with real warmth and fury, and the series is as much about holding a family together while you wait as it is about the mystery. It was filmed at the same time in Welsh and English and became the most downloaded non-network show on BBC iPlayer. The first season is the one for this list; the two that follow move on to new trouble.
