As was ever the case when his feeling seemed deeply stirred, Ixtli found it difficult to fully or fairly explain his sentiments; but Bruno caught sufficient of his meaning to give a fair guess at the rest. He found a ray of hope in the belief that Aztotl at least would defend the Children of the Sun, and Ixtli predicted with apparent confidence that the members of the body-guard would stand firm under the Red Heron's leadership. Keeping thus upon the alert throughout the remainder of that night, the young men were able to take prompt action when the crisis drew nigh. Ixtli caught the first inkling of what was coming, and hastily sent Bruno away from the peepholes, dropping a word in his ear as they both prepared for clean work. Through a secret entrance, shaped amidst the drapery which surrounded the pedestal of the mighty Huitzil', a slave of the temple crept to play the part of echo to Tlacopa's evil will; and scarcely had he secured what was to be a place of waiting and watching than the attack was made from out the darkness. Ixtli flung his tunic over the slave's head, twisting both ends tightly about his throat, effectually smothering all attempt at crying aloud for aid, while Bruno clasped arms about his middle, holding hands powerless to strike or to draw weapon. A brief struggle, which produced scarcely any noise, certainly not sufficient to reach the ears of priest or helper, then the trembling, unnerved slave was bundled down that narrow passage, to be dumped in a remote corner, and there effectually bound and gagged by the young men. All this was performed without hitch or mishap, and then, nerved to fighting pitch, Ixtli and Bruno went back beneath the stone of sacrifice, resolved to play their part to the end in manful fashion. There was no further fear of intrusion, for, of course, Tlacopa would never think of endangering his own evil scheme by risking an exposure such as would follow discovery of his slave-oracle. As Ixtli truly said, such discovery would end in the paba's being slain by his befooled people. Their patience was sorely tried, even then, though a goodly portion of the blame belonged to their fears for the Sun Children, rather than to the actual length of waiting. But then, amidst the solemn invocations led by the high priest, the body-guard marched into the Hall of Sacrifice, and Bruno caught his breath sharply as he beheld--Gladys! Not her mother, just then. For the first minute, only,--Gladys! Then came the bitter denunciation by Tlacopa, followed by the coldly dignified words of Victo, after which the innocent lamb yielded up its life in order that the future might be predicted through the still quivering heart.
