No news to report about the clock and the panelled wall dilemma. As you can see, the bowing comes from a particular point in the wall. As for why this is happening now, when we haven't seen anything like it yet, well, it's a mystery. Even my father in-law, who is pretty knowledgeable about house things in general, is stumped. It doesn't look like the wall's going to fall in on us or anything, and we're hoping that as outside temperatures decline, the wall will straighten up. In the meantime, my chime clock is still airborne, and now it can't tell time because it's tilted so much. We miss the ticking.
