The word ‘illusion’ means ‘an idea or belief that is not true’. It is inappropriate here. The correct word is ‘allusion’, which means ‘a brief or indirect reference’. This was an allusion to the most infamous murder committed by the two anti-heroines of the book as they are on the run through France.              Â
