In Search of the Great Beast 666: Aleister Crowley Directed by Simon Langton, 2004

While spending the weekend at his cottage outside London, Hercule Poirot is invited to dinner by Sir Henry and Lady Angkatell. Leaving immediately after dinner, he returns the next day to find that a weekend guest, John Christo, has been shot dead. There is any number of suspects: his former lover, Veronica Cray whom he had not seen for 12 years but suddenly turned up at a nearby cottage; his wife, Gerda who was deeply hurt by his womanizing; his current mistress Henrietta Savernake; Midge Hardcastle, who was very much in love with him, but whom he constantly ignored; and Edward Angkatell, who was in love with Midge. What Poirot finds however is that the evidence equally implicates everyone just a little too equally for it all to be just by chance.
