I've been thinking about that, myself. If she catches us slinking around her home, she won't be too happy to see us, I suspect. On the other hand, we already ARE sneaking around her house anyway, so announcing our presence might not do anymore harm than's already done.
Even if we find the wine, we're gonna need to find the thief, as well, or this'll probably just happen again.
I'm inclined to think Mole youkai, but, that seems the obvious answer, and I'm never inclined to believe the 'obvious'.
I think we should wait until Draco's next post, see what we can see, and then go from there.
EDIT: I might add, that, after the spider debacle, I'm really not looking forward to anymore trouble, so, if it's the choice between the two, I REALLY hope we get a nice friendly mole that we can tap, not a badger that'll tap us sideways with a forklift.
