Executive Producer Suzanne Mackie (The Crown) of Orchid Pictures had the following to say;

“I am excited to be bringing The Seven Dials Mystery to life, and to be introducing a new generation of iconic Christie characters to the screen. It has been a joy to work with Chris Chibnall in creating this bold, authored and ambitious vision for the series. Together with Chris Sussman and Agatha Christie Limited and, under the masterful direction of Chris Sweeney, we are thrilled to embark on this creative journey. I could not think of a more exciting first project for Orchid Pictures, or a more perfect home for this story than Netflix.”

James Prichard of Agatha Christie had the following to say about the project;

“Bundle Brent is one of my great grandmother’s raft of interesting humorous sharp young female characters. To see her brought to life through the words of Chris Chibnall and this production with Orchid Pictures and Netflix is a dream come true. I think viewers will love this world that we have created, and hope for more.”


What is the plot of The Seven Dials of Mystery?

From the Agatha Christie website, the synopsis for The Seven Dials of Mystery is;

“Gerry Wade had proved himself to be a champion sleeper; so the other house guests decided to play a practical joke on him. Eight alarm clocks were set to go off, one after the other, starting at 6.30 a.m. But when morning arrived, one clock was missing and the prank had backfired with tragic consequences.”
