The Norman Rockwell Code.

A parody of The Da Vinci Code. When the curator of The Norman Rockwell Museum in Stockbridge, Massachusetts is murdered, police call in symbology professor Langford Fife (son of Mayberry Deputy Barney Fife) to investigate. Teaming up with Sopha Poisson, the Québécoise granddaughter of the murdered curator, they set out to decode secret messages hidden in Rockwell's paintings and uncover a grand conspiracy that they may have already had an unwitting part in.
