Minako is on holiday with her parents. In Amsterdam, they are staying at a very large hotel in the heart of the city. There are mirrors all over the building. At breakfast, she sees four sad little boys who look exactly the same ? oh no, there are only two! One set of twins at breakfast and one set in the mirror. The twins just turned six. Their grandmother got them a dog, but he ran away. Minako decides she?s going to help find him. But how do you find a very small dog in a very large hotel?
