Philip has got his laptop out, and is showing Caroline and Emma an image of himself in front of the Mona Lisa, but instead of printing off some copies he manages to delete the picture completely. Sophie has also mistakenly just deleted the only other copy of the picture from the camera. Emma persuades Sophie that they could recreate the picture, with Adil's help, so their father won't find out about Sophie's error. Adil "magics up" the Mona Lisa, and the wall on which it hangs, in the hope of persuading an unsuspecting Philip to pose in front of it. The disappearance of the Mona Lisa from the Louvre causes consternation in Paris, of course, but the girls aren't too concerned, until they need to hide the painting from Caroline. Adil hides the painting where no-one will ever need to look, in the waste disposal, and the painting gets destroyed. Ever resourceful, the girls decide to bring back Leonardo Da Vinci to paint another version of the Mona Lisa. He requires paying, and his services do not come cheap, although he eventually settles for payment in Cheese Puffs, which he thinks are delicious, and Philip's Hawaiian shirt. The painting is recreated, and returned to the Louvre, after Philip has had his photograph taken in front of it. The new painting, however, is not quite the same as the old. With Joseph Long as Leonardo Da Vinci, Carl Proctor, the show's casting director, as the News Reporter and Arnold Widdowson, one of the series' regular writers, as the Police Inspector. Written by Grant Cathro. Directed by Jean-Francois Didelot.
