"I suspect that she went no further than Wasta," replied Dr. Cairn.

"Still I do not understand," declared Sime.

"You may understand later," was the answer. "We must not waste a moment. You Egyptologists think that Egypt has little or nothing to teach you; the Pyramid of Meydm lost interest directly you learnt that apparently it contained no treasure. How, little you know what it _really_ contained, Sime! Mariette did not suspect; Sir Gaston Maspero does not suspect! The late Sir Michael Ferrara and I once camped by the Pyramid of Meydm, as you have camped there, and we made a discovery--"

"Well?" said Sime, with growing interest.

"It is a point upon which my lips are sealed, but--do you believe in black magic?"

"I am not altogether sure that I do--"

"Very well; you are ent.i.tled to your opinion. But although you appear to be ignorant of the fact, the Pyramid of Meydm was formerly one of the strong-holds--the second greatest in all the land of the Nile--of Ancient Egyptian sorcery! I pray heaven I may be wrong, but in the disappearance of Lady Lashmore, and in the story of Ali Mohammed, I see a dreadful possibility. Ring for a time-table. We have not a moment to waste!"

CHAPTER XVIII

THE BATS

Rekka was a mile behind.

"It will take us fully an hour yet," said Dr. Cairn, "to reach the pyramid, although it appears so near."

Indeed, in the violet dusk, the great mastabah Pyramid of Meydm seemed already to loom above them, although it was quite four miles away. The narrow path along which they trotted their donkeys ran through the fertile lowlands of the Faym. They had just pa.s.sed a village, amid an angry chorus from the pariah dogs, and were now following the track along the top of the embankment. Where the green carpet merged ahead into the grey ocean of sand the desert began, and out in that desert, resembling some weird work of Nature rather than anything wrought by the hand of man, stood the gloomy and lonely building ascribed by the Egyptologists to the Pharaoh Sneferu.

Dr. Cairn and his son rode ahead, and Sime, with Ali Mohammed, brought up the rear of the little company.

"I am completely in the dark, sir," said Robert Cairn, "respecting the object of our present journey. What leads you to suppose that we shall find Antony Ferrara here?"

"I scarcely hope to _find_ him here," was the enigmatical reply, "but I am almost certain that he _is_ here. I might have expected it, and I blame myself for not having provided against--this."

"Against what?"

"It is impossible, Rob, for you to understand this matter. Indeed, if I were to publish what I know--not what I imagine, but what I know--about the Pyramid of Meydm I should not only call down upon myself the ridicule of every Egyptologist in Europe; I should be accounted mad by the whole world."

His son was silent for a time; then:

"According to the guide books," he said, "it is merely an empty tomb."

"It is empty, certainly," replied Dr. Cairn grimly, "or that apartment known as the King's Chamber is now empty. But even the so-called King's Chamber was not empty once; and there is another chamber in the pyramid which is not empty _now_!"

"If you know of the existence of such a chamber, sir, why have you kept it secret?"

"Because I cannot _prove_ its existence. I do not know how to enter it, but I know it is there; I know what it was formerly used for, and I suspect that last night it was used for that same unholy purpose again--after a lapse of perhaps four thousand years! Even you would doubt me, I believe, if I were to tell you what I know, if I were to hint at what I suspect. But no doubt in your reading you have met with Julian the Apostate?"

"Certainly, I have read of him. He is said to have practised necromancy."

"When he was at Carra in Mesopotamia, he retired to the Temple of the Moon, with a certain sorcerer and some others, and, his nocturnal operations concluded, he left the temple locked, the door sealed, and placed a guard over the gate. He was killed in the war, and never returned to Carra, but when, in the reign of Jovian, the seal was broken and the temple opened, a body was found hanging by its hair--I will spare you the particulars; it was a case of that most awful form of sorcery--_anthropomancy_!"

An expression of horror had crept over Robert Cairn's face.

"Do you mean, sir, that this pyramid was used for similar purposes?"

"In the past it has been used for many purposes," was the quiet reply.

"The exodus of the bats points to the fact that it was again used for one of those purposes last night; the exodus of the bats--and something else."

Sime, who had been listening to this strange conversation, cried out from the rear:

"We cannot reach it before sunset!"

"No," replied Dr. Cairn, turning in his saddle, "but that does not matter. Inside the pyramid, day and night make no difference."

Having crossed a narrow wooden bridge, they turned now fully in the direction of the great ruin, pursuing a path along the opposite bank of the cutting. They rode in silence for some time, Robert Cairn deep in thought.

"I suppose that Antony Ferrara actually visited this place last night," he said suddenly, "although I cannot follow your reasoning.

But what leads you to suppose that he is there now?"

"This," answered his father slowly. "The purpose for which I believe him to have come here would detain him at least two days and two nights. I shall say no more about it, because if I am wrong, or if for any reason I am unable to establish my suspicions as facts, you would certainly regard me as a madman if I had confided those suspicions to you."

Mounted upon donkeys, the journey from Rekka to the Pyramid of Meydm occupies fully an hour and a half, and the glories of the sunset had merged into the violet dusk of Egypt before the party pa.s.sed the outskirts of the cultivated land and came upon the desert sands. The mountainous pile of granite, its peculiar orange hue a ghastly yellow in the moonlight, now a.s.sumed truly monstrous proportions, seeming like a great square tower rising in three stages from its mound of sand to some three hundred and fifty feet above the level of the desert.

There is nothing more awesome in the world than to find one's self at night, far from all fellow-men, in the shadow of one of those edifices raised by unknown hands, by unknown means, to an unknown end; for, despite all the wisdom of our modern inquirers, these stupendous relics remain unsolved riddles set to posterity by a mysterious people.

Neither Sime nor Ali Mohammed were of highly strung temperament, neither subject to those subtle impressions which more delicate organisations receive, as the nostrils receive an exhalation, from such a place as this. But Dr. Cairn and his son, though each in a different way, came now within the _aura_ of this temple of the dead ages.

The great silence of the desert--a silence like no other in the world; the loneliness, which must be experienced to be appreciated, of that dry and tideless ocean; the traditions which had grown up like fungi about this venerable building; lastly, the knowledge that it was a.s.sociated in some way with the sorcery, the unholy activity, of Antony Ferrara, combined to chill them with a supernatural dread which called for all their courage to combat.

"What now?" said Sime, descending from his mount.

"We must lead the donkeys up the slope," replied Dr. Cairn, "where those blocks of granite are, and tether them there."

In silence, then, the party commenced the tedious ascent of the mound by the narrow path to the top, until at some hundred and twenty feet above the surrounding plain they found themselves actually under the wall of the mighty building. The donkeys were made fast.

"Sime and I," said Dr. Cairn quietly, "will enter the pyramid."

"But--" interrupted his son.

"Apart from the fatigue of the operation," continued the doctor, "the temperature in the lower part of the pyramid is so tremendous, and the air so bad, that in your present state of health it would be absurd for you to attempt it. Apart from which there is a possibly more important task to be undertaken here, outside."

He turned his eyes upon Sime, who was listening intently, then continued:

"Whilst we are penetrating to the interior by means of the sloping pa.s.sage on the north side, Ali Mohammed and yourself must mount guard on the south side."

"What for?" said Sime rapidly.

"For the reason," replied Dr. Cairn, "that there is an entrance on to the first stage--"
