About the book: 2012 / Rico is not an ordinary child; many basic things are difficult for him. “Unusually gifted,” his loving mother calls him. “Moron,” the evil neighbor upstairs simply says. Few people want to be friends with someone like Rico, but one day he was lucky - he met Oscar (also not an ordinary boy - a child prodigy who, just in case, never takes off his blue motorcycle helmet from his head). And for the sake of his new friend, Rico undertakes to unravel a case that has been baffling the entire Berlin police for six months. For middle school children.
