Fan Casting Arc 3 Culprit in Nancy Drew The Animated Series Season 1

While it is revealed that Abby was causing fake hauntings throughout the house with special effects, she isn't the one causing the accidents. THAT was Louis, who had learned that Valdez had hid the gold he had stolen somewhere in the mansion. When Nancy and George finally find Valdez's gold, Louis attacks them and attempts to steal the gold. However, thanks to some quick thinking, Nancy drops the chandelier onto Louis, trapping him until the authorities arrive. Thanks to finding the gold, the bank that had owned it back then awards Rose and Abby with enough money to finish renovations on the BnB. The arc ends clearing up that there's no such thing as ghosts... probably.
