Creativity! It's like making sausages.
Who would have thought that a well-travelled chest of drawers could serve as a plot device for a book. Sylvia Vetta bought it and then wrote about it and then fashioned an entire novel about it. This is something only truly creative people can do. They see something and it churns around inside their heads and comes out in all sorts of ways. Umberto Eco, author of the Name of the Rose, once wrote an article about how creativity was like making sausages - you never throw anything away.
Here is the article that Sylvia first published about her well-travelled chest of drawers.
