The live of sisters Theresa and Helen, and their families are turned upside down when a young boy, Alex is found dead.
It's a slow burner it's fair to say, it improves as it goes on, and ends with a cracking episode, unfortunately episode one is a real clunker. You wouldn't be blamed for switching it off after fifteen minutes, the opener is painful.
It's very well made, smart looking, and features some wonderful acting, Anna Maxwell Martin and Rachel Stirling give amazing performances, particularly in Part four.
It's a clever murder mystery, a whodunnit, you'll guess and wonder, I'm not sure you'll get it, I certainly didn't.
This would have been better over two nights. It's a slow burner, but ultimately rewarding in the end.
Overall, pretty good, 7/10.
