Kuno und Karo fangen den Diamantendieb

From 1999 onward, Arena published this single-issue comic by writer Friederun Reichenstätter and artist Stephan Baumann. It follows young sleuths Kuno and Karo as they set out to catch a diamond thief. A concise, charming entry in German children’s comics, it showcases the duo’s first and only case.
