‘Agatha Christie’s Seven Dials’ Review: Lavish Netflix Adaptation Builds to a Terrible Ending

It’s a classic setup: a country house, a party full of colorful characters, and at some point during the night, a murder. For Lady Eileen “Bundle” Brent (Mia McKenna-Bruce), a glamorous shindig at her family home is an opportunity to get close to Gerry Wade (Corey Mylchreest), a Foreign Office employee for whom she harbors a soft spot. But the very next morning, Gerry is found dead in his bed. Everyone suspects it to be an accident or suicide. But not Bundle, and she won’t stop until she uncovers the truth.
