"The king was in the counting house counting out his money,
the queen was in the parlour eating bread and honey...."

The flag was flying, so it must be presumed that "royalty" was in residence. I heard one of the guides say to a child, that sometimes the queen waves to her public from one of the windows. Well, I kept a keen eye open for the royal wave; must have missed it when my back was turned.
