It's like James frames it as a ghost story, which I think most ghost stories take for granted that the ghost is real. And then that's just supposed to scare you or make you think about other things. Whereas if he had just kind of written it without that frame narrative, it might be a bit more of the like unreliable narrator thing. But I don't know a lot of unreliable narrators from the 19th century. That seems like a very 20th century thing to do.
