Greta Anderson is the secondary antagonist of Agatha Christie's 1967 crime novel, Endless Night. She is Ellie Rogers's Scandinavian, blonde companion with a penchant for arranging and often compared with a valkyrie. In secret, Greta was working with Michael Rogers into killing his wife and obtain her wealth.

She was portrayed by Britt Ekland in the 1972 film adaptation, and by Birgitte Hjort Sørensen in Agatha Christie's Marple which adapted the novel in 2013 and added Miss Marple in it.


Originally, Rogers was shown to meet Greta after he and Ellie was wed. However, in the middle of the story, it was revealed that Rogers already met Greta in Germany before he met Ellie. They have fell in love and was desperate for a better life. They then devised a plan to kill off Ellie and get married. Rogers poisoned Ellie's allergic capsules with cyanide, which killed her during her ride.

However, by the end of the book, Rogers broke down in remorse and revealed himself to be haunted by a vision of Ellie on his way back to the Gypsy's Arch, his new home with her. Greta, however, rebuked Rogers' remorse as weakness and showed utter disdain upon his house. Rogers went infuriated and strangled Greta in rage.
