In this exciting children's book, the sheep Charlotte takes center stage, as she plays the lead role in a real sheep mystery. One day, the smallest lamb on the farm disappears without a trace. Shortly after, another lamb goes missing, and then even one more. All the animals are terribly upset but do nothing, while the children Max and Line argue about who will solve the case first. Fortunately, sheep have great insight, and Charlotte especially so. She puts two and two together and ensures that the culprit can set things right. Because, in fact, there isn't really a thief at all... An adventure among sheep that's full of laughter and fun.
