The Mystery of the Candies in Golden Wrapping

Grandma Lorentzia hadn't even moved in yet when thieves broke into her house. Could it be that the old owners left a key? Or were they specifically targeting them?The case is taken up by Lorentzia's grandchildren - brave raccoons Toly and Polya. After all, the theft is more than strange: a brooch made of gemstones and a box of candies are missing. And the young detectives already have their first suspect - the neighbor's fox Leon, who litters with wrappers from exactly the same candies.
