Agatha Christie’s Seven Dials Mystery (1981)

A lavish weekend party in a venerable old house promises to be frightfully jolly. Punting and pranks top the agenda until one morning a late sleeper doesn’t wake up at all. Another death, whispers of a secret society called the Seven Dials and stolen state secrets thicken the plot.

Feisty Lady Eileen “Bundle” Brent (Cheryl Campbell) runs her roadster right into the middle of the mystery and teams up with charming “man about town” Jimmy Thesiger (James Warwick) to find the fiends. Full of sly Christie wit, this ingenious mystery also features Sir John Gielgud in top form as Bundle’s distracted but indulgent father.

Based on The Seven Dials Mystery (1929), the all-star cast includes Sir John Gielgud, Rula Lenska and John Vine.
