I was rootling around on Google yesterday doing a bit of research for the ghost novella when I came across a link to this article, eye-catchingly headed "8 Houses That Are Actually Haunted".
Needless to say, I just had to go and have a look, but perhaps unsurprisingly the content failed to live up to the headline. Not only were many of the details vague and unproveable (footsteps in a supposedly empty house could so easily be someone who'd got in unseen), but 'actually' hardly applies to Borley Rectory since it burned down in the 1940s!
I remember seeing a much longer description of both Borley Rectory (which does sound as though it had a thoroughly unpleasant atmosphere, whether you believe in ghosts or not), and those faces on the Spanish floor, in a book I had as a kid. Back then, the faces really spooked me. Now I can't help thinking they look very much like medieval tiles, which would, of course, hardly be out of place on an ancient floor.
Ah well. It's still an entertaining read, and good source material if you're looking for a creepy setting for a story or three.
