“Do you know what it is?”

“Bichloride of mercury, your majesty. One dose would have been sufficient, and after a few days—perhaps a week—you would have died in great agony.”

Barney shuddered.

“But I am not the king, Joseph,” said the young man, “so even had they succeeded in killing me it would have profited them nothing.”

Joseph shook his head sadly.

“Your majesty will pardon the presumption of one who loves him,” he said, “if he makes so bold as to suggest that your majesty must not again deny that he is king. That only tends to corroborate the contention of Prince Peter that your majesty is not—er, just sane, and so, incompetent to rule Lutha. But we of Tann know differently, and with the help of the good God we will place your majesty upon the throne which Peter has kept from you all these years.”

Barney sighed. They were determined that he should be king whether he would or no. He had often thought he would like to be a king; but now the realization of his boyish dreaming which seemed so imminent bade fair to be almost anything than pleasant.

Barney suddenly realized that the old fellow was talking. He was explaining how they might escape. It seemed that a secret passage led from this very chamber to the vaults beneath the castle and from there through a narrow tunnel below the moat to a cave in the hillside far beyond the structure.

“They will not return again tonight to see your majesty,” said Joseph, “and so we had best make haste to leave at once. I have a rope and swords in readiness. We shall need the rope to make our way down the hillside, but let us hope that we shall not need the swords.”

“I cannot leave Blentz,” said Barney, “unless the Princess Emma goes with us.”
