"Going back on you?" repeated Anita, showing her pretty white teeth in an amused smile. "What shall you mean by that 'going back on you'—eh? You are a stupid little donkey, to be sure. But then I do not care to get on the back of one—so why?"

"Oh, you know very well what I mean," he rapped out angrily. "It is not fair the way you have been treating me ever since that yellow-headed bounder came. I've had a night of misery—Zuilika never showing herself; you doing nothing, absolutely nothing, although you promised—you know you did!—and I heard you, I absolutely heard you persuade that St. Aubyn fool to stop at least another night."

"Yes, of course you did. But what of it? He is good company—he talks well, he sings well, he is very handsome and—well, what difference can it make to you? You are not interested in me, amigo?"

"No, no; of course I'm not. You are nothing to me at all—you—Oh, I beg your pardon; I didn't quite mean that. I—I mean you are nothing to me in that way. But you—you're not keeping to your word. You promised, you know, that you'd use your influence with Zuilika; that you'd get her to be more kind to me—to see me alone and—and all that sort of thing. And you've not made a single attempt—not one. You've just sat round and flirted with that tow-headed brute and done nothing at all to help me on; and—and it's jolly unkind of you, that's what!"

Cleek heard Anita's soft rippling laughter; but he waited to hear no more. Moving swiftly away from the well-hole of the staircase he passed on tiptoe down the hall to the Major's rooms, and, opening the door, went in. The old soldier was standing, with arms folded, at the window looking silently out into the darkness of the night. He turned at the sound of the door's opening and moved toward Cleek with a white, agonised face and a pair of shaking, outstretched hands.

"Well?" he said with a sort of gasp.

"My dear Major," said Cleek quietly. "The wisest of men are sometimes mistaken—that is my excuse for my own short-sightedness. I said in the beginning that his was either a case of swindling or a case of murder, did I not? Well, I now amend my verdict. It is a case of swindling and murder; and your son has had nothing to do with either!"

"Oh, thank God! thank God!" the old man said; then sat down suddenly and dropped his face between his hands and was still for a long time. When he looked up again his eyes were red, but his lips were smiling.

"If you only knew what a relief it is," he said. "If you only knew how much I have suffered, Mr. Cleek. His friendship with that Spanish woman; his going with her to identify the body—even assisting in its hurried burial! These things all seemed so frightfully black—so utterly without any explanation other than personal guilt."

"Yet they are all easily explained, Major. His friendship for the Spanish woman is merely due to a promise to intercede for him with Zuilika. She is his one aim and object, poor little donkey! As for his identification of the body—well, if the widow herself could find points of undisputed resemblance, why not he? A nervous, excitable, impetuous boy like that—and anxious, too, that the lady of his heart should be freed from the one thing, the one man, whose existence made her everlastingly unattainable—why, in the hands of a clever woman like Anita Rosario such a chap could be made to identify anything and to believe it as religiously as he believes. Now, go to bed and rest easy, Major. I'm going to call up Dollops and do a little night prowling. If it turns out as I hope, this little riddle will be solved to-morrow."
