Mona Lisa
The painting is thought to be a portrait of Lisa Gherardini, the wife of Francesco del Giocondo, and is in oil on a white Lombardy poplar panel. It had been believed to have been painted between 1503 and 1506; however, Leonardo may have continued working on it as late as 1517. Recent academic work suggests that it would not have been started before 1513. It was acquired by King Francis I of France and is now the property of the French Republic, on permanent display at the Louvre Museum in Paris since 1797.
Mona Lisa's Revenge
The Mona Lisa tries to unleash a beast in the gallery basement, which she refers to as her brother. This creature is locked up in a vault and can only be released by using a puzzle box key. This key is destroyed by Harding who, despite his admiration for La Gioconda, cannot allow her to unleash the beast on the world. Luke, Clyde, and Rani have to try to solve the problem without Sarah Jane as she is now trapped in a painting. The Dark Rider captures Clyde and takes him to the vaults along with the Mona Lisa and Harding. As Mr Harding has destroyed the original key, Clyde is encouraged to draw another, that the Mona Lisa can bring to life as a replacement. This is done and the key is used, but before the beast can escape, a picture of K-9 drawn by Clyde also comes to life and fires at the beast, causing it to retreat into the vault. This sets off a chain reaction causing all the painting people to revert to being just works of art, and all those trapped in paintings to be released. The story ends with the Mona Lisa restored to her frame and Luke promising to tidy his room.Pearson Education published a simplified novelisation of this episode by Trevor Baxendale under the title "Painting Peril" for school literacy programs in September 2010.
