“I am frightened,” she gasped.  “I cannot bear it—­she looks so still, and she is growing—­rigid, like a corpse!  Oh, if she should be dead!” And she hid her face on her husband’s breast.

At that moment we heard the grating of wheels on the gravel outside; it was the Challoners’ carriage returned.  The coachman, after depositing his master and family at the Grand Hotel, had driven rapidly back in the teeth of the stinging sleet and rain to bring the message that Dr. Morini would be with us as soon as possible.

“Then,” whispered Colonel Everard gently to me, “I’ll take Amy home.  She is thoroughly upset, and it’s no use having her going off into hysterics.  I’ll call with Challoner to-morrow;” and with a kindly parting nod of encouragement to us all, he slipped softly out of the room, half leading, half carrying his trembling wife; and in a couple of minutes we heard the carriage again drive away.

Left alone at last with Heliobas and Father Paul, I, kneeling at the side of my darling Zara, looked into their faces for comfort, but found none.  The dry-eyed despair on the countenance of Heliobas pierced me to the heart; the pitying, solemn expression of the venerable priest touched me as with icy cold.  The lovely, marble-like whiteness and stillness of the figure before me filled me with a vague terror.  Making a strong effort to control my voice, I called, in a low, clear tone: 

“Zara!  Zara!”

No sign—­not the faintest flicker of an eyelash!  Only the sound of the falling rain and the moaning wind—­the thunder had long ago ceased.  Suddenly a something attracted my gaze, which first surprised and then horrified me.  The jewel—­the electric stone on Zara’s bosom no longer shone!  It was like a piece of dull unpolished pebble.  Grasping at the meaning of this, with overwhelming instinctive rapidity, I sprang up and caught the arm of Heliobas.

“You—­you!” I whispered hurriedly.  “You can restore her!  Do as you did with Prince Ivan; you can—­you must!  That stone she wears—­the light has gone out of it.  If that means—­and I am sure it does—­that life has for a little while gone out of her, you can bring it back.  Quick—­Quick!  You have the power!”

He looked at me with burning grief-haunted eyes; and a sigh that was almost a groan escaped his lips.

“I have no power,” he said.  “Not over her.  I told you she was dominated by a higher force than mine.  What can I do?  Nothing—­ worse than nothing—­I am utterly helpless.”

I stared at him in a kind of desperate horror.

“Do you mean to tell me,” I said slowly, “that she is dead—­really dead?”

He was about to answer, when one of the watching servants announced in a low tone:  “Dr. Morini.”

The new-comer was a wiry, keen-eyed little Italian; his movements were quick, decisive, and all to the point of action.  The first thing he did was to scatter the little group of servants right and left, and send them about their business.  The next, to close the doors of the room against all intrusion.  He then came straight up to Heliobas, and pressing his hand in a friendly manner, said briefly:
