"Of a certainty not, monsieur. Gustave, show the good doctor how you go about it when papa lets you do the trick. But you are not really to do it just yet, only to bend the head near to Nero's mouth. Now then, come, see." As he spoke he divided the lion's jaws and signalled the child to bend. He obeyed. Very slowly the little head drooped nearer to the gaping, full-fanged mouth, very slowly and very carefully, for Cleek's hand was on the boy's shoulder, Cleek's eyes were on the lion's face. The huge brute was as meek and as undisturbed as before, and there was actual kindness in its fixed eyes. But of a sudden, when the child's head was on a level with those gaping jaws, the lips curled backward in a ghastly parody of a smile, a weird, uncanny sound whizzed through the bared teeth, the passive body bulked as with a shock, and Cleek had just time to snatch the boy back when the great jaws struck together with a snap that would have splintered a skull of iron had they closed upon it. The hideous and mysterious "smile" had come again, and, brief though it was, its passing found the boy's sister lying on the ground in a dead faint, the boy's stepmother cowering back, with covered eyes and shrill, affrighted screams, and the boy's father leaning, shaken and white, against the empty case and nursing a bleeding hand. In an instant the whole place was in an uproar. "It smiled again! It smiled again!" ran in broken gasps from lip to lip; but through it all Cleek stood there, clutching the frightened child close to him, but not saying one word, not making one sound. Across the dark arena came a rush of running footsteps, and presently Señor Sperati came panting up, breathless and pale with excitement. "What's the matter? What's wrong?" he cried. "Is it the lion again? Is the boy killed? Speak up!" "No," said Cleek very quietly, "nor will he be. The father will do the trick to-night, not the son. We've had a fright and a lesson, that's all." And, putting the sobbing child from him, he caught young Scarmelli's arm and hurried him away. "Take me somewhere that we can talk in safety," he said. "We are on the threshold of the end, Scarmelli, and I want your help." "Oh, Mr. Cleek, have you any idea--any clue?" "Yes, more than a clue. I know how, but I have not yet discovered why. Now, if you know, tell me what did the chevalier mean, what did his wife mean, when they spoke of a dream that might have come true, but didn't? Do you know? Have you any idea? Or, if you have not, do you think your fiancée has?" "Why, yes," he made reply. "Zelie has told me about it often. It is of a fortune that was promised and never materialized. Oh, such a long time ago, when he was quite a young man, the chevalier saved the life of a very great man, a Prussian nobleman of great wealth. He was profuse in his thanks and his promises, that nobleman; swore that he would make him independent for life, and all that sort of thing." "And didn't?"
