I was curious - what was the angle on Hythe in the book?

These days Hythe seems like a posh seaside town with a Waitrose, a nice canalside park, a cute steam railway, lots of boutiquey shops and cafes, etc.

I know a lot of places in the area (e.g. Folkestone, Margate, Whitstable) have all been heavily "gentrified" in the last few years, but I sort of assumed Hythe was always this way? Is that not the case?

And even allowing for a bit of gentrification, it seems wild in 2025 to select it for a "crap towns" award ahead of somewhere like Dover or New Romney.
