It was around perhaps midday when a bat came fluttering in. It was shinier than it should be and perhaps if one looked close enough, one could see tiny gears and pieces of metal that held it all together. What was more interesting was the small brown parcel clutched in it's feet, big enough to fit about two cauldron cakes. Held closed with a simple white string, it looked innocent enough. The bat landed on the desk next to the dropped parcel.

No note on the outside, but it's messenger should have been familiar enough.
