The Seven Dials Mystery plot

The series will unfold in England in 1925 in the countryside – how many great Christie mysteries unfold, of course.

According to the official synopsis: "At a lavish country house party, a practical joke appears to have gone horribly, murderously wrong.

"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."

The original novel by Christie was published in 1929 and was released as a TV movie in 1981, following young aristocrat Bundle, who finds herself looking into a series of murders.

The series is being executive produced by The Crown's Suzanne Mackie, of Orchid Pictures, and Chris Sussman (Good Omens).

On the announcement of the series, Mackie said: "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 Limited) also said: "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."
