Absolute Power

From: Martha
Description: The Huntress said that sometimes she encounters psy-werewolves branded with a mark. I found the mark that the Huntress described to me in the Book of Magical Seals. It’s a symbol of submission. If the Doctor placed it, we’ll find the seal among his things. Can you help?
Completed: The Detective found the Doctor’s fingerprints on the seal of submission you brought. This means we were right to assume that the scientist branded psy-werewolves in order to completely bend the creatures to his will. But is there a third interested party in this story?
