Found them!

Pretty flashy, huh? You'd think it would be hard to lose something this, er, bright. But lose one we did, for a good 24 hours. It wasn't in her bin, where I expected it to be, nor in any of the likely spots: under a piece of furniture, on the stairs, in a toy bin.
But wait! Did something just glitter in the dog's crate?
Let's take a closer look... Yes, yes that's where it was.
And while the culprit may seem to be clear, the evidence is merely circumstantial. A critical piece of missing data is the fact that Dominic and Nora both looooooove to drop things through the bars and into the dog's house.

We may never know who was responsible for the purloined bling, but Willa is very happy to have them back!
