Blind Walls

It's a monstrous maze of a mansion, built by a grief-ridden heiress. A tour guide, about to retire, has given his spiel for so many years that he's gone blind. On this last tour, he's slammed with second sight.
He sees the ghosts he's always felt were there: the bedeviled heiress, her servants, and a young carpenter who lands his dream job only to become a lifelong slave to her obsession. The workman's wife makes it to shore, but he's cast adrift.
And the tour guide comes home to his cat.
