Slightly confused

I'm re-reading the essay I got given feedback on on Thursday (I got a 1st in it - the highest distinction you can get for a piece of work in this country - I was very chuffed about it)
The assignment was to re-write a seventeenth century Spanish story we had read in class as a pitch for a contemporary TV drama, along with a 500 word commentary about what choices we had made and why. Here's what I wrote:
"When we consider Spanish prose of the Golden Age, Miguel de Cervantes is definitely considered one of the auteurs of this field. Of his Novelas Ejemplares he wrote “no hay ninguna de quien no se pueda sacar algún ejemplo provechoso” , meaning that the stories should be both educational and entertaining. Whilst this is a concept that bears relevance to a contemporary readership, many elements of the original work are now out-dated and difficult to understand outside of the original historical context.
The story has been relocated from Seville in the seventeenth century to modern-day New York City. This serves as the place for the male protagonist to live out his days “en quietud y sosiego” and this rings true for both versions. "
After that, I continue talking about "the story", "the characters" etc., but only now do I realise that I never said what the story is! I've not mentioned "El Celoso Extremeno", which is the story in question. I don't even mention it until 500 words in... how did the assesor not flag that up?
Not complaining, though. I was expecting to do awfully in this essay and instead I did one of the best papers in the entire class... not complaining, not complaining at all
