 After being in hospital, Danny discovers a famous art collector, Meredith Gates, who has an exhibition in London. Her most prized pieces are those by Mondrian, and the gang comes up with the idea to make a fake Mondrian to sell to Meredith. However, so that Tip Jones, the art forger (or "cloner"), can design the masterpiece, he needs many materials from all over the world, including an existing real Mondrian to help him - but can the team steal one from the exhibition? Will the gang manage to convince Meredith that it was actually Mondrian who invented cubism before picking it up from Picasso? And how will the team resolve the "jinx" that has been plagued upon them when nearly all their money is going into this painting?
