Netflix Releases Three-Episode Agatha Christie Adaptation 'The Seven Dials Mystery'

Chris Chibnall spotlights Bundle Brent as an unusually young sleuth, with Ronda, Spain, setting the series’ tone from the first scene.

Overview

  • The miniseries launched globally on January 15, 2026, with all three episodes available to stream.
  • Set in 1925 England, the story begins with a country-house death that draws Lady Eileen “Bundle” Brent into a larger conspiracy tied to the Seven Dials.
  • Mia McKenna-Bruce leads the cast, with Helena Bonham Carter and Martin Freeman among the principal players.
  • Filming took place in summer 2024 in Bristol and Bath and on location in Ronda, whose Plaza de Toros, Puente Nuevo, Fuente de los Ocho Caños, Palacio del Rey Moro, Arco de Felipe V and Alameda del Tajo appear after digital period restoration.
  • A local report identified Iain Glen in early footage, though his involvement has not been confirmed by official cast lists or the trailer.
