The Heat of the Day is a novel written by Elizabeth Bowen, first published in 1948 in the United Kingdom, and in 1949 in the United States of America. The Heat of the Day revolves around the relationship between Stella Rodney and her lover Robert Kelway, with the interfering presence of Harrison in the tense years following the Blitz in London. Harrison, a British intelligence agent who is convinced that Robert is a German spy, uses this knowledge to get between the two lovers and ultimately neutralise Robert. Stella finds herself caught between spy and counterspy. The narrative reveals the "inextricable knitting together of the individual and the national, the personal and the political."
