I happened to find the pilot episode if this BBC comedy on the iPlayer and I enjoyed it so much I ended up binge watching the entire series.
Basically it’s about 2 half sisters who find each other following their fathers death . Born only a few days apart and strangely both named “Catherine” They are like chalk and cheese .
I do hope there’s a second series, I enjoyed it so much .
