On paper it shouldn’t work. EastEnders characters Kat and Alfie Moon, a soap couple of some 16 years standing, show up in Ireland for their own six-part series on BBC1. Forget everything you think and feel about soap, however, because this series is nothing like EastEnders.

The pair are in the village of Redwater to find Kat’s long-lost son. What they discover is a place steeped in mystery with a dark underbelly. It’s gripping and surprising, has a thoroughbred cast of Irish actors and is more filmic than soap. Worth delving into even if you’ve never heard of Kat and Alfie.
