The Sibyl in Her Grave, by Sarah Caudwell.
Oxford professor Dr. Hilary Tamar (gender unknown) is the narrator. Here she (or he, as the case may be) comments on the season:
It was, as I have mentioned, the second week of August: that season of the year when the warm days of summer draw luxuriantly towards their fruitful and abundant climax and there is an almost universal impulse to give thanks in some way for the richness and generosity of the earth; that is to say, in the case of an upper-class Englishman, to go out and kill something.
This has to be one of the most entertaining first person narrators I have come across, but I expect he (or she, as the case may be) would be terrifying in a class-room.
