The Adventure of the Clapham Cook by Agatha Christie A Poirot short story published 14 November 1923
Poirot is not interested in investigating some of the cases which appear in the newspapers and which Hastings tries to bring to his attention. These include a bank clerk (Mr.Davis) who disappears with fifty thousand pounds of securities, a suicidal man and a missing typist. He is put on the spot though when visited by a Mrs Todd who is determined that he investigate her missing cook. Challenged, he decides, with some humour and to avoid an argument, to take the seemingly trivial case. Eliza Dunn, a middle-aged woman, walked out of her job and the Todd'shouse in Clapham two days ago without working her notice and has not communicated with her employer since, except for sending for her trunk that day.
