He had grown suddenly paler; his eyes were dancing, fastened upon her breast. His long hands closed and opened. She looked down, arrested at the sight of her hand clenched just where her breath was shortest, over the sapphire's hiding-place.

He smiled. How easily she had betrayed herself! But she abated not a jot of her defiance, challenging him, now he knew its hiding-place, to take the sapphire if he could. But he did not move. And it came to her then that she had been ridiculous to think for an instant that this man would take anything from her by force. What she had to fear was his will at work upon hers, his persuasion, his ingenuity. She thought of the purple irises, and how he had drawn them toward him in the crook of his cane—and her dread was lest he meant to overcome her with some subtlety she could not combat. For that he was secret, that he was daring, that he was fearless beyond belief, he showed her all too plainly, since here he stood, condemned by his own evidence, alone, in the midst of her household, within call of her servants, and had the sublime effrontery to look at her with admiration, and, it occurred to her, even with a little pity.

The click of a moving latch brought his eyes from hers to the door.

"Some one is coming in," he said in a guarded voice. It warned her that her face showed too much, but she could not hope to recover her composure. She hardly wanted to. She was in a state to fancy that a secret could be kept by main force; and she turned without abatement of her reckless mood and took her hand from where she had held it clenched upon her breast and stretched it out to Mrs. Herrick.

The lady had stood in the doorway a moment—a long-featured, whitish, modeled face, draped in a dull green veil, a tall figure whose flowing skirts of black melted away into the background of the hall—before she came forward and met her hostess' hand with a clasp firm and ready.

"I'm so glad to find you here," she said. She looked directly into Flora's eyes, into the very center of her agitation. She held her tremulous hand as if neither of these manifestations surprised her; as if a young woman and a young man in colloquy might often be found in such a state of mind.

Flora's first emotion was a guilty relief that, after all, her face had not betrayed Kerr. But she had no sooner murmured his name to Mrs. Herrick, no sooner had that lady's gray eyes lighted upon him, than they altered their clear confidence. The situation as reflected in Flora looked naïve enough, but there was nothing naïve about Kerr. The very perfection of his coolness, there in the face of her burning agitation, was appalling. Oh, why couldn't he see, Flora thought wildly, how it was damning him—how it was showing him so practised, so marvelously equal to any emergency, that his presence here among fleeces could be nothing less than wolfish?

Mrs. Herrick's face was taking on an expression no less than wary. What he was, Mrs. Herrick could not dream. She could not even suspect what Flora believed. But in the light of her terrible discovery Flora dared not have him suspected at all. The chasms of distrust and suspicion that had been opening between them she forgot. In a flash she was ready to throw herself in front of this man, to cover him from suspicion, even though by so doing she took it upon herself.

Now, if she had ever in her life, she talked over the top of her feelings; and though at first to her ears her voice rang out horribly alone, presently Mrs. Herrick was helping her, adding words to words. It was the house they spoke of, the San Mateo house, the subject about which Flora knew Mrs. Herrick had come to talk; but to Flora it was no longer a subject. It was a barrier, a shield. In this emergency it was the only subject large enough to fill the gap, and much as Flora had liked the idea of it, she had never built the house so large, so vivid, so wonderfully towering to please her fancy as she was doing now to cover Kerr. With questions she led Mrs. Herrick on to spin out the subject, to play it over with lights and shades, to beat all around it. And all the while she knew that Kerr was watching her; watching her once again in dubious admiration. It was a look that made Mrs. Herrick seem ready at a movement of his to lay her hand on Flora in protection.

The lady's clear gray eyes traveled between Flora's face and his. Under their steady light there was a strange alertness, as if she sat there ready enough to avert whatever threatened, but anxious to draw her skirts aside from it, distrusting the quality, hating to have come in upon anything so dubious. When the hall door opened and closed she listened as if for a deliverer; and when Clara appeared between the portières she turned to her and met her with a flash of relief, as if here at last was a safe quantity. Clara was still wearing her hat, with the veil pushed up in a little mist above her eyes, and still had her white gloves on. The sight of Mrs. Herrick's hand soliciting the clasp of those gave Flora a curious sensation.
