Plot
Ben, an 11-year-old boy, hates his granny and hates having to stay with her every week because his parents go to see a dancing show. He finds her boring and repetitive because his granny always feeds him cabbage-related dishes, most commonly cabbage soup, they are constantly playing Scrabble and her television hasn't been working since the 1980's.
One day, Ben calls his parents and asks them to take him home. It is suggested that his gran overhears the conversation as he cannot hear her snoring. The next day, his gran seems somewhat depressed and crestfallen.
On his next stay, his granny tells him she is an international jewel thief, stealing her first diamond when she was very young, and living in the country, from a nearby large mansion.
