It is impossible to describe the strain of agony in the young man's voice; his sudden pallor; the sweat starting from his forehead; or to describe the piercing power of his eye, as he turned it from the face of his sister to that of his guest. Accustomed as he was to every form of suffering, Dr. Graham shrank from the appeal in that searching look, which mutely asked him if there were any hope.

The clear whisper in which St. Victor had spoken aroused Edith from her revery; she darted a glance at both parties, so full of suspicion and dread, so in contrast with her natural sunny expression, that it was as if her face had suddenly withered, from that of a child, to the thin features of the careworn woman of fifty. She half rose in her chair, faltered, sank back, and sat gazing fixedly at the two men; yet silent as a statue.

St. Victor was the first to recover himself. He burst into a light laugh,—sweet as a shower of flowers,—and, taking up a slender-necked decanter of pale wine, passed it to his guest, remarking,—

"We are forgetting that this is Christmas night. Fill your glass, my friend, with this wine,—the oldest and rarest of our precious store,—and I will fill mine. Then, we will both drink joyously to the health of my only darling—my one beloved—my sister."

He said this so prettily, poured out the wine with such arch pleasantry of gesture, that the color came back to Edith's cheeks; and when the two men bowed to her, before drinking, she gave them a smile, steeped in melancholy, but very sweet, and brimming with affection. It thrilled Dr. Graham's veins more warmly than the priceless wine.

"After our mother's death," continued St. Victor, in his natural voice, "we found ourselves quite alone. We had formed no great attachment to our relatives in France; and, as one branch of our father's business remained still unsettled in this country, we resolved to come hither. Then, too, we had a longing to behold the land which was our mother's. When we had arranged and closed up our affairs in Madeira, we sailed for France, where we spent one winter only. I thought"—with a tender glance at his sister—"that a sea voyage would do Edith good. I was not satisfied about her health; so I drew her away from Paris, and, last spring, we fulfilled our promise to see our mother's land, and came hither. I am afraid the climate here does not agree with her. Do you think she looks well?"

The girl moved uneasily, casting a beseeching look at the speaker.

"It is not I who am not strong," she said; "it is you, St. Victor. If your friend is a doctor, I wish he would give a little examination into the state of your health. You are thin and nervous; you have no appetite,—while he can see, at a glance, that nothing in the world ails me."

Again her brother laughed; not gayly as before, but with a peculiar and subtle significance; while he gave the doctor another swift glance, saying to him in a low voice,—

"I have heard that persons threatened with certain mental afflictions never suspect their own danger."
