Trick or Treat

My name is Nadia, and I'm a Marshal of the High Queen of the Elves, which means I have a lot of responsibilities. 

Some of them are ceremonial, and that includes overseeing trick-or-treating for the children of friends and family.

But when a criminal hides a stolen item at a Halloween party, I need to think quickly.

Else a lot of people are going to have a much scarier Halloween than they really want...
