Set in England in 1925, Agatha Christies Seven Dials follows Lady Eileen 'Bundle' Brent, an inquisitive young socialite who investigates events at a lavish country-house weekend after a practical joke turns apparently murderous. As Bundle probes hidden alliances and secret societies centered on the enigmatic Seven Dials, she uncovers a conspiratorial plot that transforms her role from amateur guest to central investigator in a classic country-house mystery.
