We are a class of Year Three children and we loved this story. This is the second Jack Stalwart book we have read. Jack is a ten-year-old boy who is also a Secret Agent working for the GPF (Global Protection Force), solving mysteries and crimes around the world. In this book Jack is sent on a mission to save the famous Mona Lisa painting which has been stolen from the Louvre in Paris, France. Using his bag of powerful, incredible gadgets he cleverly escapes being caught by the flame-haired criminal and sneakily manages to rescue the priceless painting from under the robbers' very noses. A page-turning story which kept us wondering what would happen next. We would definately recommend this series. Each book has different gadgets and adventures in different countries.
