"You are tired out," he said gently. "You have been nursing him?"

She nodded and tried to smile.

"Who is attending?"

"Sir Elwin Groves, but--"

"Shall I wire for my father?"

"We wired for him yesterday!"

"What! to Paris?"

"Yes, at my uncle's wish."

Cairn started.

"Then--he thinks he is seriously ill, himself?"

"I cannot say," answered the girl wearily. "His behaviour is--queer.

He will allow no one in his room, and barely consents to see Sir Elwin. Then, twice recently, he has awakened in the night and made a singular request."

"What is that?"

"He has asked me to send for his solicitor in the morning, speaking harshly and almost as though--he hated me...."

"I don't understand. Have you complied?"

"Yes, and on each occasion he has refused to see the solicitor when he has arrived!"

"I gather that you have been acting as night-attendant?"

"I remain in an adjoining room; he is always worse at night. Perhaps it is telling on my nerves, but last night--"

Again she hesitated, as though doubting the wisdom of further speech; but a brief scrutiny of Cairn's face, with deep anxiety to be read in his eyes, determined her to proceed.

"I had been asleep, and I must have been dreaming, for I thought that a voice was chanting, quite near to me."

"Chanting?"

"Yes--it was horrible, in some way. Then a sensation of intense coldness came; it was as though some icily cold creature fanned me with its wings! I cannot describe it, but it was numbing; I think I must have felt as those poor travellers do who succ.u.mb to the temptation to sleep in the snow."

Cairn surveyed her anxiously, for in its essentials this might be a symptom of a dreadful ailment.

"I aroused myself, however," she continued, "but experienced an unaccountable dread of entering my uncle's room. I could hear him muttering strangely, and--I forced myself to enter! I saw--oh, how can I tell you! You will think me mad!"

She raised her hands to her face; she was trembling. Robert Cairn took them in his own, forcing her to look up.

"Tell me," he said quietly.

"The curtains were drawn back; I distinctly remembered having closed them, but they were drawn back; and the moonlight was shining on to the bed."

"Bad; he was dreaming."

"But was _I_ dreaming? Mr. Cairn, two hands were stretched out over my uncle, two hands that swayed slowly up and down in the moonlight!"

Cairn leapt to his feet, pa.s.sing his hand over his forehead.

"Go on," he said.

"I--I cried out, but not loudly--I think I was very near to swooning.

The hands were withdrawn into the shadow, and my uncle awoke and sat up. He asked, in a low voice, if I were there, and I ran to him."

"Yes."

"He ordered me, very coldly, to 'phone for his solicitor at nine o'clock this morning, and then fell back, and was asleep again almost immediately. The solicitor came, and was with him for nearly an hour.

He sent for one of his clerks, and they both went away at half-past ten. Uncle has been in a sort of dazed condition ever since; in fact he has only once aroused himself, to ask for Dr. Cairn. I had a telegram sent immediately."

"The governor will be here to-night," said Cairn confidently. "Tell me, the hands which you thought you saw: was there anything peculiar about them?"

"In the moonlight they seemed to be of a dull white colour. There was a ring on one finger--a green ring. Oh!" she shuddered. "I can see it now."

"You would know it again?"

"Anywhere!"

"Actually, there was no one in the room, of course?"

"No one. It was some awful illusion; but I can never forget it."

CHAPTER III

THE RING OF THOTH

Half-Moon Street was very still; midnight had sounded nearly half-an-hour; but still Robert Cairn paced up and down his father's library. He was very pale, and many times he glanced at a book which lay open upon the table. Finally he paused before it and read once again certain pa.s.sages.

"In the year 1571," it recorded, "the notorious Trois Ech.e.l.les was executed in the Place de Greve. He confessed before the king, Charles IX.... that he performed marvels.... Admiral de Coligny, who also was present, recollected ... the death of two gentlemen.... He added that they were found black and swollen."

He turned over the page, with a hand none too steady.

"The famous Marechal d'Ancre, Concini Concini," he read, "was killed by a pistol shot on the drawbridge of the Louvre by Vitry, Captain of the Bodyguard, on the 24th of April, 1617.... It was proved that the Marechal and his wife made use of wax images, which they kept in coffins...."

Cairn shut the book hastily and began to pace the room again.
