The Mona Lisa mystery

Would you risk the future to change the past? Luna, Konstantin and Aidan are time-travelling thieves working for The Butterfly Club. When they are asked to steal a little-known painting called the Mona Lisa, Aidan can only think of one man who can make things disappear - the magician, Harry Houdini. And as luck would have it, Houdini cannot resist a challenge. The three children and Houdini travel to 1911 Paris where they face an impossible task - stealing a painting right off the wall of the fortress-like Louvre Museum.

Her creator, Leonardo Da Vinci, hid mysterious codes within the painting. The race is on to solve the puzzle in time...
