Masterstroke of Malevolence was the thirteenth episode of Fillmore! to be produced and the tenth to air. It was originally broadcast on February 15, 2003
Fillmore, Ingrid and O'Farrell get the day off thanks to a field trip. But what should be a quiet trip to an art museum turns noisy when a prize painting gets a new addition...an ink marker mustache. Unless they can find the marker that was used to deface the painting before the ink dries, the masterpiece will be ruined forever. It's a classic whodunit with plenty of suspects, and not a lot of time to put the pieces together.
- This is the only episode where an adult is responible for the crime.
