Fingerprints
A:N: Here's one for all the Animaniacs fans out there. You know I had to do this at some point.
"In order to solve this mystery, we need to search for clues," Hermione declared, her bushy hair bristling like she'd just passed through an electrical storm. "Harry, you're familiar with Muggle methods, so I want you to dust for fingerprints while I question the students in the common room."
Harry scurried off, trying his best to be useful.
"Ron, it's going to be a long night," Hermione continued, turning towards the red haired wizard. "I want you to go to the kitchen and ask the house elves if they'll make us some snacks."
Ron eagerly hurried out the door, thinking he could stuff his face while his friends did all the work.
A short while later, Harry stepped through the entrance with Professor Snape. "I found Prince!" he announced to everyone in the common room.
Hermione shook her head. "No, no, no. I said fingerprints."
Harry looked at the Professor. "Yeah, I don't think so."
