The next morning the coal said to the king:—
“Again this night have I saved your treasure, and mayhap your life as well. Yet a third time I shall do it, and this time you shall learn the name of the thief. But if I do this, you must promise me one thing, and that is that you will place me in your royal crown and wear me as a jewel. Will you do this?”
“That will I, right gladly!” replied King Sligo, “for a jewel indeed you are.”
“That is well!” said the coal. “It is true that I am dying; but no matter. It is a fine thing to be a jewel in a king’s crown, even if one is dead. Now listen, and follow my directions closely. As soon as I am quite black and dead,—which will be in about ten minutes from now,—you must take me in your hand and rub me all over and around the handle of the door of the treasure-chamber. A good part of me will be rubbed off, but there will be enough left to put in your crown. When you have thoroughly rubbed the door, lay the key of the treasure-chamber on your table, as if you had left it there by mistake. You may then go hunting or riding, but not for more than an hour; and when you return, you must instantly call all your court together, as if on business of the greatest importance. Invent some excuse for asking them to raise their hands, and then arrest the man whose hands are black. Do you understand?”
“I do!” replied King Sligo, fervently, “I do, and my warmest thanks, good Coal, are due to you for this—”
But here he stopped, for already the coal was quite black, and in less than ten minutes it was dead and cold. Then the king took it and rubbed it carefully over the door of the treasure-chamber, and laying the key of the door in plain sight on his dressing-table, he called his huntsmen together, and mounting his horse, rode away to the forest. As soon as he was gone, the High Cellarer, who had pleaded a headache when asked to join the hunt, crept softly to the king’s room, and to his surprise found the key on the table. Full of joy, he sought the treasure-chamber at once, and began filling his pockets with gold and jewels, which he carried to his own apartment, returning greedily for more. In this way he opened and closed the door many times. Suddenly, as he was stooping over a silver barrel containing sapphires, he heard the sound of a trumpet, blown once, twice, thrice. The wicked thief started, for it was the signal for the entire court to appear instantly before the king, and the penalty of disobedience was death. Hastily cramming a handful of sapphires into his pocket, he stumbled to the door, which he closed and locked, putting the key also in his pocket, as there was no time to return it. He flew to the presence-chamber, where the lords of the kingdom were hastily assembling.
The king was seated on his throne, still in his hunting-dress, though he had put on his crown over his hat, which presented a peculiar appearance. It was with a majestic air, however, that he rose and said:—
“Nobles, and gentlemen of my court! I have called you together to pray for the soul of my lamented grandmother, who died, as you may remember, several years ago. In token of respect, I desire you all to raise your hands to Heaven.”
The astonished courtiers, one and all, lifted their hands high in air. The king looked, and, behold! the hands of the High Cellarer were as black as soot! The king caused him to be arrested and searched, and the sapphires in his pocket, besides the key of the treasure-chamber, gave ample proof of his guilt. His head was removed at once, and the king had the useful coal, set in sapphires, placed in the very front of his crown, where it was much admired and praised as a Black Diamond.
