In the palace of Ruby land there was a ruby thief. No one knew who it was, and the thief had everyone so fooled that the only thing known about him was that he lived in the palace, and that when you were in the palace you should always hide your jewels.
The King decided to find out who it was, and he asked for help from a wise dwarf who was famed for his intelligence. The dwarf spent some days there, watching and listening, until there was another theft. The following morning the wise dwarf made all the palace inhabitants meet up together in the same room.

And the footman, now found out, was arrested by the guards and taken immediately to court.
The King, grateful, generously rewarded his wise adviser, and when he asked the dwarf what his secret was, the dwarf smiled and said:
-“I only try to get the person knowing the truth to reveal that truth.”
