Netflix has released the trailer for Agatha Christie’s Seven Dials, its murder mystery starring Mia McKenna-Bruce and Helena Bonham Carter. It is based on the author’s 1929 novel of the same name. The three-part series will be available for streaming starting on January 15, 2026.
“England. 1925. At a lavish country house party, a practical joke appears to have gone horribly, murderously wrong,” reads the official synopsis. “It will be up to the unlikeliest of sleuths — the fizzingly inquisitive Lady Eileen ‘Bundle’ Brent, to unravel a chilling plot that will change her life, cracking wide open the country house mystery.”
