Wednesday on Britbox: The Agatha Christie classic, first published in 1944, gets a glossy BBC makeover. The arch three-part miniseries, set in the 1930s, stars Hollywood royalty Anjelica Huston as the bedridden widow Lady Camilla Tressilian. The aristocratic owner of an English seaside estate hosts a coterie of strange and suspicious characters. Upon the discovery of a corpse, Inspector Leach (“
Perry Mason”’s Matthew Rhys) arrives to exhume secrets and unravel the mystery. Christie’s adeptness at plot and keeping audiences guessing never grows old.
