Kari is shocked by a rude comment made by a man painting at an easel in her local art museum. When she goes to a London museum she sees the same man, but in disguise, painting there too. He's trying hard to hide what it is he's painting and that, combined with the disguise, makes Kari suspicious. What is he painting? Could he be forging one of Rembrandt's paintings? Kari and her friend Lucas decide to solve the mystery and it takes them from Minneapolis to London to Paris and Amsterdam. While the adults are skeptical at first, this mystery turns out to be both serious and dangerous. The best part is, it gets solved by kids!
