He turned on more lights and began to scan the rows of books.

Presently--

"Here it is," he said, and took down and opened the book on the table.

"This pa.s.sage may interest you." He laid his finger upon it.

His son bent over the book and read the following:--

"Hai, the evil man, was a shepherd. He had said: 'O, that I might have a book of spells that would give me resistless power!' He obtained a book of the Formulas.... By the divine powers of these he enchanted men. He obtained a deep vault furnished with implements. He made waxen images of men, and love-charms. And then he perpetrated all the horrors that his heart conceived."

"Flinders Petrie," said Dr. Cairn, "mentions the Book of Thoth as another magical work conferring similar powers."

"But surely, sir--after all, it's the twentieth century--this is mere superst.i.tion!"

"I thought so--_once_!" replied Dr. Cairn. "But I have lived to know that Egyptian magic was a real and a potent force. A great part of it was no more than a kind of hypnotism, but there were other branches.

Our most learned modern works are as children's nursery rhymes beside such a writing as the Egyptian _Ritual of the Dead_! G.o.d forgive me!

What have I done!"

"You cannot reproach yourself in any way, sir!"

"Can I not?" said Dr. Cairn hoa.r.s.ely. "Ah, Rob, you don't know!"

There came a rap on the door, and a local pract.i.tioner entered.

"This is a singular case, Dr. Cairn," he began diffidently. "An autopsy--"

"Nonsense!" cried Dr. Cairn. "Sir Elwin Groves had foreseen it--so had I!"

"But there are distinct marks of pressure on either side of the windpipe--"

"Certainly. These marks are not uncommon in such cases. Sir Michael had resided in the East and had contracted a form of plague. Virtually he died from it. The thing is highly contagious, and it is almost impossible to rid the system of it. A girl died in one of the hospitals this week, having identical marks on the throat." He turned to his son. "You saw her, Rob?"

Robert Cairn nodded, and finally the local man withdrew, highly mystified, but unable to contradict so celebrated a physician as Dr.

Bruce Cairn.

The latter seated himself in an armchair, and rested his chin in the palm of his left hand. Robert Cairn paced restlessly about the library. Both were waiting, expectantly. At half-past two Felton brought in a tray of refreshments, but neither of the men attempted to avail themselves of the hospitality.

"Miss Duquesne?" asked the younger.

"She has just gone to sleep, sir."

"Good," muttered Dr. Cairn. "Blessed is youth."

Silence fell again, upon the man's departure, to be broken but rarely, despite the tumultuous thoughts of those two minds, until, at about a quarter to three, the faint sound of a throbbing motor brought Dr.

Cairn sharply to his feet. He looked towards the window. Dawn was breaking. The car came roaring along the avenue and stopped outside the house.

Dr. Cairn and his son glanced at one another. A brief tumult and hurried exchange of words sounded in the hall; footsteps were heard ascending the stairs, then came silence. The two stood side by side in front of the empty hearth, a haggard pair, fitly set in that desolate room, with the yellowing rays of the lamps shrinking before the first spears of dawn.

Then, without warning, the door opened slowly and deliberately, and Antony Ferrara came in.

His face was expressionless, ivory; his red lips were firm, and he drooped his head. But the long black eyes glinted and gleamed as if they reflected the glow from a furnace. He wore a motor coat lined with leopard skin and he was pulling off his heavy gloves.

"It is good of you to have waited, Doctor," he said in his huskily musical voice--"you too, Cairn."

He advanced a few steps into the room. Cairn was conscious of a kind of fear, but uppermost came a desire to pick up some heavy implement and crush this evilly effeminate thing with the serpent eyes. Then he found himself speaking; the words seemed to be forced from his throat.

"Antony Ferrara," he said, "have you read the _Harris Papyrus_?"

Ferrara dropped his glove, stooped and recovered it, and smiled faintly.

"No," he replied. "Have you?" His eyes were nearly closed, mere luminous slits. "But surely," he continued, "this is no time, Cairn, to discuss books? As my poor father's heir, and therefore your host, I beg of you to partake--"

A faint sound made him turn. Just within the door, where the light from the reddening library windows touched her as if with sanct.i.ty, stood Myra Duquesne, in her night robe, her hair unbound and her little bare feet gleaming whitely upon the red carpet. Her eyes were wide open, vacant of expression, but set upon Antony Ferrara's ungloved left hand.

Ferrara turned slowly to face her, until his back was towards the two men in the library. She began to speak, in a toneless, unemotional voice, raising her finger and pointing at a ring which Ferrara wore.

"I know you now," she said; "I know you, son of an evil woman, for you wear her ring, the sacred ring of Thoth. You have stained that ring with blood, as she stained it--with the blood of those who loved and trusted you. I could name you, but my lips are sealed--I could name you, brood of a witch, murderer, for I know you now."

Dispa.s.sionately, mechanically, she delivered her strange indictment.

Over her shoulder appeared the anxious face of Mrs. Hume, finger to lip.

"My G.o.d!" muttered Cairn. "My G.o.d! What--"

"S--sh!" his father grasped his arm. "She is asleep!"

Myra Duquesne turned and quitted the room, Mrs. Hume hovering anxiously about her. Antony Ferrara faced around; his mouth was oddly twisted.

"She is troubled with strange dreams," he said, very huskily.

"Clairvoyant dreams!" Dr. Cairn addressed him for the first time. "Do not glare at me in that way, for it may be that _I_ know you, too!

Come, Rob."

"But Myra--"

Dr. Cairn laid his hand upon his son's shoulder, fixing his eyes upon him steadily.

"Nothing in this house can injure Myra," he replied quietly; "for Good is higher than Evil. For the present we can only go."

Antony Ferrara stood aside, as the two walked out of the library.

CHAPTER IV

AT FERRARA'S CHAMBERS

Dr. Bruce Cairn swung around in his chair, lifting his heavy eyebrows interrogatively, as his son, Robert, entered the consulting-room.
