chunk: During an evening's game of dominoes with friends, Madame Raquin manages to move her finger with an extreme effort of will to trace words on the table: "Thérèse et Laurent ont ...". The complete sentence was intended to be "Thérèse et Laurent ont tué Camille" (Thérèse and Laurent killed Camille). At this point her strength gives out, and the words are interpreted as "Thérèse and Laurent look after me very well".
  Eventually, Thérèse and Laurent find life together intolerable and plot to kill each other. At the climax of the novel, the two are about to kill one another when each of them realizes the plans of the other. They each then break down sobbing and reflect upon their miserable lives. After having embraced one last time, they each commit suicide by taking poison, all in front of the watchful gaze of Madame Raquin.
