The Mysterious Incident at the Vienna Ball Larry Mystery is not the most successful student in his detective school, but he is good at tap dancing. Only at the Vienna Ball, where he is sent on a new assignment, it is customary to waltz! True, the dance is just an excuse to constantly be with the young aristocrat, guarding the “Tear of Burmese,” a unique family jewel that the girl will wear to her first ball. Of course, the jewel very quickly disappears from under the nose of the unlucky detective. But nothing will escape the penetrating gaze of his sister Agatha!
