The nurse speaks these words to Meursault during the long, hot funeral procession in Part One, Chapter 1. On a literal level, the nurse's words describe the dilemma the weather presents: the heat's influence is inescapable. But Meursault's comment, "There was no way out,"" broadens the implications of the nurse's words.
