“Yuri then besieged Luno Castle, for the Princess Lilla and the baby King had had no opportunity to leave it during the battle. Under threat of airplane bombardment the defenders finally surrendered, on the strength of Yuri’s solemn promise to harm no person, to take only Lilla back to Kuana, to maintain her there as befitted her royal rank, and to permit all others free passage to join your army for the safety of the infant king, and on Poblath’s advice, the princess consented. So Yuri sent a strong detachment over by boat to carry out his promise.” “Did he carry out his promise?” asked the earth man. “He did,” replied his host with a peculiar gleam in his eye. “Then, _who_ killed my baby?” exclaimed Cabot. X TREACHERY “Who killed your baby?” replied the venerable old man of the Caves of Kar. “I will tell you. Even such a traitor as the renegade Yuri would not dare to violate his solemn oath. He had sworn to harm no person. Yet little Kew stood between him and a coveted throne. What could he do under such circumstances? Only a diabolical brain, like that possessed by Yuri, could conceive of the solution which he concocted. In his capacity as king and hence interpreter of all laws, he interpreted his own promise as follows—” “Yes, yes! Go on!” exclaimed Cabot, exasperated. “Don’t keep me in suspense.” “I was just about to tell you when you interrupted me,” resumed Glamp-glamp in a mildly reproving tone. “Prince Yuri ruled that, because little Kew was your son, and because you are a beast from another world, therefore little Kew was a beast, likewise, and so was not a ‘person,’ strictly speaking, and so did not come within the literal scope of the protection of the promise, which was ‘to harm no _person_.’ Having ruled thus, the miscreant then proceeded to stab the baby through the heart with his own hands.” “The villain!” hissed Cabot, clenching his fists. But what could a mere earth man do against such a schemer? Glamp-glamp went on with his story: “He left his jeweled dagger sticking in the death wound which it had made, sneeringly remarking: ‘Thus, with the seal of my family, I seal the deed which makes me King of Cupia.’ So came King Yuri the First to the Cupian throne.” “Not yet, by a long shot!” exclaimed the earth man, with a sudden burst of loyalty and affection toward the man whom he had wrongly suspected all this while, “for you forget Prince Toron. The Assembly long ago canceled Yuri’s title to the crown because of his treason in the Great War of Liberation. The succession they awarded to his younger brother, the loyal Toron. So Yuri’s foul deed made Toron king, unless”—and here a horrible fear clouded Cabot’s firmament—“unless Toron is among the missing.” “You have spoken well,” replied the old man, “for Toron truly is among the missing. He has not been seen or heard of since the assassination of the old king.”
