The first exciting case for Kalle Blomquist, the master detective! He is currently bored to death because he is not in London or Chicago, where crime is rampant, but in the quiet little town of Kleinköping in Sweden! However, he then discovers a strikingly shimmering pearl in an old castle ruin, and shortly after, he hears about a major jewel theft. This is the first unabridged reading of the Lindgren classic, narrated by the number one audio drama detective, Oliver Rohrbeck.
