Claw marks left on storage units

Exploration Stage: City Hall
From: Detective
Description: If the doctor was planning revenge, wouldn't it be natural to send the werewolves he has following him to get to the guy? Why go all the way to city hall? We need to find out what he was looking for. I see the werewolf's claw marks on the shelves over there, too. Let's find a step ladder and check it out.
Completed: Thanks for finding this stomping ground. I see the werewolf scratches on this one, too. Hey, there's a document stuck next to the claw marks. Let's see what it says.
