Another Da Vinci Code parody: Alfred Thomas Catalfo's The Norman Rockwell Code. From the website:
A famous museum... a shocking murder... a distinguished symbologist... an alluring cryptologist... secrets written in code.
No, it's not that "other" story.
Movie Shot When the curator of The Norman Rockwell Museum in Stockbridge, Massachusetts, is murdered, the police desperately need help with the investigation. Langford Fife, Professor of Symbology at Stockbridge Community College and the son of a certain Deputy Sheriff from Mayberry, North Carolina, is called to the scene. He may have received his degree in symbology through a correspondence course but he's "just as competent as those high-falutin' professors from Harvard with their fancy sheepskins from accredited schools."
With cryptologist Sopha Poisson of the Quebec Secret Service, Langford sets out to uncover the clues hidden in the paintings of Norman Rockwell... clues which will lead them to a secret society, a legendary bloodline and a battle with sinister forces.
