A transient and not really unpleasant fishy smell in Puerto Escondido a few days ago reminded me of A Shadow Over Innsmouth, so I started to read it.
I first read it about fifteen years ago. My assessment of Lovecraft then was that he was strong on ideas, weak on character, plot, and style. But a revision of my opinion was in order. Stylistically Lovecraft was much stronger than I had realized. Indeed, I was surprised by how Borgesian Shadow was, especially in its opening pages.
A worthy rediscovery.
