A story for younger readers.
When Lucy's Grandma comes over from Italy to stay, there are lots of problems, especially when Grandma arrives wearing "witchy black" clothes. Worse still, Lucy isn't allowed to go on the class farm holiday. She has to "grandma-sit" instead.
But "grandma-sitting" leads Lucy into lots of adventures, the unravelling of the mystery of the secret box and pride in her Italian heritage.
