This is not the only Brighton. There is a city called Brighton on every continent. There is even a bar of that name in Antarctica (it is little more than a cupboard with a fridge of beer, but it does have a reputation).
There is a New Brighton in the Wirral. And there is a Brighton Beach in New York, on the Coney Island peninsular. There are Brightons on the shores of Australia and New Zealand, places linked only by their haphazard naming.
But the mystery is the landlocked Brightons, the ones without a seafront, where the name seems like mockery. Places with no piers, no beaches, and no waves. But sometimes, in the heart of the night, a lonesome seagull can be heard crying in Brighton, Illinois.
