Goodbye, Mrs. Boynton. I hope you'll have a nice trip. You've wanted to be very rude to me. You've tried to prevent your son and daughter making friends with me. Don't you think, really, that that is all very silly and childish? You like to make yourself out a kind of ogre, but really, you know, you're just pathetic and rather ludicrous. If I were you I'd give up all this silly play-acting. I expect you'll hate me for saying this, but I mean it-and some of it may stick. You know you could have a lot of fun still. It's really much better to be friendly and kind. You could be if you tried.
~ Sarah King's commet towards Lady Boynton and her death

Sarah King, also known as Nurse King, is a nurse for Boynton family and a major protagonist in Agatha Christie's 1938 Hercule Poirot novel, Appointment With Death. She is also the lover of Raymond Boynton and the archenemy of his abusive mother, Lady Boynton.

She was portrayed by Jenny Seagrove in 1988 film, and by Christina Cole in the 2008 television film from Agatha Christie's Poirot, who previously portrayed Lettice Protheroe in Agatha Christie's Marple.


Nurse Sarah King was in love with Raymond Boynton, the eldest son of the abusive Lady Boynton, who detested her for coming from a low-standard family. Being disgusted by Lady Boynton's control freak behavior, Nurse King and her friends like Dr. Gerard, her colleague and working partner, were planning to help Boynton children to leave their mother's tyrannical control, being sympathized with their experience, before the murder of Lady Boynton occured. She later assisted Poirot in investigating the case.

Sarah King revealed to Poirot that she was verbally mistreated by Lady Boynton, and had overheard the abusive lady threating her that she (Lady Boynton) never forget about anything, something that she once thought it was for her.

Nevertheless, it turned out to be a threat to the real culprit of the case, who was once a prisoner but now stayed in a high status. The culprit killed Lady Boynton only to keep their dark past in secret. After the case was solved and the culprit killed themselves, Nurse King married Raymond Boynton, who was finally relieved from his mother's control alongside all of his siblings.
