Mr. Tristan Quick is a P.E Teacher at The Bruce Stock Academy in the NPLH universe portrayed by Paul Ballard. Coming from a broken home and falling into a bad crowd, Quick was always on the fast-track to destruction. His debts grew and his gambling habit increased, but eventually was saved by his sporting skills. He was appointed P.E Teacher for the Academy after being spotted playing by the founder, Bruce Stock.
But all of this good work goes to waste episode "Reign Will Fall", in which he appears as the main suspect behind the theft of the school funds. Eventually, the truth is revealed by Holmes, and Miss Constance is found to be the mastermind behind the theft, resulting in a forced resignation, and allowing Mr. Quick to remain in his role.
