I'm currently writing a horror serial set in contemporary Liverpool and I'd love to set some of it under the city. I'm researching the Williamson Tunnels, gonna go take a look next week, but I was wondering whether anyone has any links or stories about the underground - specifically, are there tunnels down there that don't get used anymore, where do they go, are there any ghost stories people know of set down there? Any help, signposting etc would be very gratefully received!!
ps. I know there's some discussions on tunnels already here but I'm specifically thinkin about the tubes, and also drawing on old ghost stories.
