Your Scholarly Diploma
A return gift from Young Moriarty.
This diploma certifies that you meet the scholarly requirements of a high school graduate. James Moriarty conducted a rigorous examination before certifying your graduation. It carries no legal power...except, according to Moriarty:
"I assure you, show this to any school, and you'll be a qualified graduate."
Mysterious in the extreme, but you gratefully accept.
