Agatha Christie's Seven Dials plot: A prank that leads to murder

The plot comes from Christie’s 1929 novel, The Seven Dials Mystery. The story is set in the wealthy world of England in 1925. A group of wealthy young guests gathers at a grand country house party. These guests decide to play a lighthearted trick on Gerry Wade. Gerry Wade is known for sleeping soundly. They set eight alarm clocks to wake him early.

The joke turns horribly, murderously wrong. Wade is found dead. One of the eight clocks is mysteriously missing. This shocking event forces one guest to act. Lady Eileen "Bundle" Brent has a sharp curiosity. She becomes the unexpected detective. Her search leads her far beyond the manor.

Bundle must unravel a chilling plot of Agatha Christie's Seven Dials. The plot involves secrets, international intrigue, and a secretive organization called the Seven Dials. The story promises clever twists that only a Christie tale can deliver.
