A few years back I was reading 'Rivers of London' by Ben Aaronovitch on the London Underground on my way to work when I realised he was talking about a body being found in the actual tunnel I was passing though at the time.
Back in the early '00s I read Stoker's Dracula and then just by chance ended up going to England for a work assignment. I visited Whitby and saw the steps at the church that Stoker described. Utterly amazing to be in a place described in a book written 100+ years prior.
