Alice Vernon writes as an investigator rather than as a believer or a debunker, which is the harder and more interesting position to hold. Ghosted sits across three of our shelves at once, spirituality, society and travel, and that spread tells you most of what you need to know about her method: she treats hauntings as something people do as much as something people see.
The result is writing that takes belief seriously without surrendering to it. Places are visited, accounts are weighed, and the question quietly shifts from whether ghosts are there to why we keep going out to look for them. It is a curious, generous line of enquiry, and it gives the book an appeal well beyond the usual audience for the paranormal.
