It's about an investigator of Erocide, which is the murder of a couple's cupid. It's their real world manifestation of love for one another. When you kill the cupid, the love ends.
It reads like a monologue, or a rant even, stream of consciousness. This made it fairly easy reading. It kind of reminded me of the style of Catcher in the Rye. Except while that book condemns vulgarity, this short story is extremely vulgar. However, it is not obscene.
"The Death of Love" is the result of a great idea, and exploring the idea is what the story is about. I thought it was an interesting concept and metaphor for love.
