"There are none to make," replied Frank. "Look here: there has been some serious fighting, of course, and I believe both the Emir and his son are away, or we should have seen them here."

"It's of no use to argue with you, Frank," cried the professor pettishly. "You have an answer for everything. I'm sure you will be stopped."

"Never mind," said Frank. "I am going to try what a bold stroke will do. If I am turned back I must get leave through our young chief another day, and chance dropping a word in Harry's ear."

"I have done," said the professor. "Try."

Frank nodded, and signed to the old Sheikh to come to them.

He came, looking extra solemn and quiet.

"You will go to the head guard, Ibrahim, and tell him I want my horse as soon as it can be brought to the door."

"Yes, Excellency."

"You will then saddle your best camel and spread upon it, so that they can be seen, this bit and bridle and trappings. If the guard asks where I am going you can tell him that I am going to take a present to the young chiefs friend."

"Yes, Excellency. He will be sure to ask."

"Good," said Frank, and the old man went out without another word, while Frank coolly prepared for his short journey by putting on the rich robe that had been given to him, and buckling on his sword and knife, finishing off with a handsome turban of the kind the desert warriors wore.

"Here is Ibrahim back," said the professor, as he saw the old man reappear before Frank was ready. "He is coming to say that you cannot have a horse."

"But he has gone to get his camel ready all the same," said Frank, smiling, and about a quarter of an hour later the Arab that Frank rode was led ambling up to the door of their quarters by one of the guard.

The young man turned to give his friends a calm, smiling look of triumph, as he walked towards the window to glance at his steed. The next moment his countenance fell. For he had seen the gate from where he stood, and there, as if ready to accompany him wherever he went alone, was the chief guard, already mounted, and behind them, ready too and well-armed, were half a dozen men.

"Ah!" said the doctor, with a sigh. "I feared there would be something like this."

"Yes," said the professor; "they have us safely, and do not mean to let us go."

"The young chief must have left word," said Frank bitterly, as he ground his teeth.

"Of course, then, you give it up now?" said the professor quickly.

"No," said Frank firmly, "I am going to start--at once."

The lips of both his friends parted as if to utter a protest, but there was something so determined in Frank's eyes, so stern and set about the lines of his mouth, that they forbore, and the doctor spoke gently--

"Very well, Frank, lad," he said gravely; "you have had far more experience among these people in the city than I have, and you know the need of caution. Take care; a slip may mean destruction now we have climbed so near the pinnacle of our hopes. I will say no more than this--Go, and Heaven protect you."

"Yes," said the professor earnestly, and he held out his hand.

Frank grasped it firmly, and that of the doctor, who took his left, all three standing silently for a few minutes.

Then Frank turned to go, but hesitated for a moment or two, for the professor was running his eye over him critically.

"What is it?" said the younger man.

"I was looking to see if there is anything about you that might raise suspicion."

"Well?"

"Nothing, my lad. I have had years of dealings with the people, and I should never take you for anything but a native of the desert."

Frank nodded, and was mute again, as he walked out and across the path to where his horse was waiting the beautiful animal whinnying softly in token of recognition, and stretching out its velvety muzzle for the caress that was always given and enjoyed. The next minute the rider was in the saddle, with the Arab tossing its head and ambling gently beneath him.

CHAPTER THIRTY SIX.

THE REACTION.

Out by the gate in the dazzling sunshine sat Ibrahim upon his tall camel, the headgear for the present carefully arranged so as to make a brave show, and the seven mounted guards waiting for the Hakim's learned slave, who bore the reputation now of being deeply versed in magic to such an extent that he could call down lightning from the skies and make it do his will. A horror this to the ignorant Soudanese, and something to make them tremble, but no exaggeration. For to us of this century who can send our messages to the other side of the earth and receive back answers in a few hours; talk with friends at a distance, and recognise their voices; receive their speeches, their songs, or the melodies of instruments impressed on wax, to reproduce whenever we please; these and scores of other such scientific marvels are but everyday matters of business, common trifles, though they dwarf many of the magic legends of the Arabian Nights.

Consequently the Hakim's black slave was greeted with profound reverence by the Emir's bodyguard as he rode out, stern and thoughtful, upon the mission which he felt to be the greatest of his life, and barely noted that his beautiful horse ambled along as if proud of this rider in the flowing white robes, and whose richly ornamented sword beat softly upon its flank.

Frank gave one glance back, however, to see that the Sheikh's camel was pacing along a few yards behind, the thick, long, scarlet horsetail plume waving beneath the ungainly animal's neck, while the seven hors.e.m.e.n rode, fiercely important, a few yards behind the Sheikh, each with his round bossed target and gleaming spears.

For one moment Frank thought of self, and how strange it all was that he, the young Englishman, accustomed to London and its ways, the student of chemistry, full of experimental lore, should be riding there in disguise, the Hakim's slave and a.s.sistant--the favourite of a powerful Baggara Emir and his son--riding through the teeming crowds of that hive of horror, bloodshed, and misery, and those familiar with his appearance making way at once. It was all like a dream for a few moments, or as if he were reading with strong imagination some romantic work descriptive of a scene in the south and east. Then it was all real again--horribly real--and he rode gently on, thinking of the part he had to play, and wondering wildly whether he would have the nerve to go through all he had mentally planned, and whether if he were successful in getting alone with his brother, Harry would bear the announcement of there being help at hand.

"It all depends on me," thought the adventurer, as he rode on, stern, and gazing straight before him, hardly conscious of the crowd through which he pa.s.sed, or the whispers of the people who recognised the Hakim's follower; for he was busy working out his plans and picturing the scene in which he was to play that critical part.

It might be that the lives of all would be at stake if he failed in carrying out what he had devised, and no wonder that his face grew more set, his eyes darker with thought, till, as it seemed to him, he found himself at the entrance to the chiefs enclosure and home, with the court dotted with horse and foot, camels tethered here and there, some standing dreamily munching, others crouched down with their long necks outstretched upon the sand, and their leaders and riders idling about, talking, playing games, or smoking, waiting till their masters needed them for some mission, perhaps to raid and plunder, or to join other bands upon some great movement instigated by Mahdi or Khalifa, whose steps would be marked in blood.

There was no hesitation. Frank rode boldly in, unquestioned, and not one of the many men scattered about ran to horse or camel, or grasped his weapons. It did not seem strange to them that the Hakim's follower should ride in to see their chief, followed by a camel and seven of a friendly Emir's bodyguard. What took their attention at once--they being men whose lives had been spent in company with the swift horses of the desert--were the bright, gaily ornamented trappings spread on the neck of Ibrahim's fine camel, and a low murmur of satisfaction arose as they gazed at what was evidently a present for their lord.

Frank rode slowly across the wide, open court, with his eyes wandering wildly in search of his brother; but he was not visible, and he let them rest for a few moments upon the long, low, shed-like building into which he had seen him go at a former visit, that evidently being the place where the chiefs horses were stabled when he was in the city, the open heavens being their roof when halting among the wind-swept sands.

Frank drew rein close to the entrance, his guard halted a dozen yards in the rear, and Ibrahim, after urging his tall camel close behind, made the beast kneel down, and then dismounted, leaving the scarlet trappings full in view upon the animal's back, before going forward to his master's side, fully conscious that every movement was closely watched, and standing respectfully attent while the Hakim's black follower made a few quick signs.

Ibrahim bowed low, and went up to the house, where a knot of armed men received him and listened to the message he delivered, one going in at once, and the old Sheikh waiting ceremoniously till his messenger came back and spoke. Then the old man returned as he came, to whisper to Frank, who nodded shortly and then sat motionless and stern, gazing straight at the door as if deep in thought and ignoring everything around.

He played his part well, knowing what a battery of keen eyes were directed at him, while hors.e.m.e.n, foot, and camel riders whispered and told those who did not know, of how this dumb black follower of the Hakim was nearly as great a prophet and doctor as his master, and how they had cured hundreds, from great chiefs dying of their wounds down to children going blind from the ophthalmic curse of the desert lands.

The murmur of this whispering and the loud, ceaseless buzz of the myriads of flies darting here and there over the sand and lighting again and again upon the superheated walls, when they were not torturing horse, camel and man, fell strangely upon Frank's ears as he grew more calm, and his doubts and fears died out now that the step had been made, and he felt ready to wonder at the calmness and confidence he displayed.

The great trouble he had now was to master the intense desire to look round to see if the face he sought was gazing at him from some window or doorway, as curiously as were the rest, and he would have given anything to turn in his saddle and bring his eyes to bear in the search. But he had well determined upon his course of action: he sat rigidly in his place with his eyes fixed upon the doorway about which the chief's followers were grouped, till there was a slight stir and the stern-looking warrior appeared, looking fierce and imperious, as he strode slowly out and acknowledged Frank's haughty bow, when his countenance relaxed a little, but a.s.suming ignorance of the present upon the camel, he advanced with open hand to greet his visitor, saying a few words of meaningless welcome.

Frank bowed again and turned slowly to the Sheikh, who bent low, and then in a few well-chosen words spoke of the intense grief felt by his master, the great help and chosen friend of the wonderful Hakim, of whose miraculous cures the n.o.ble Baggara chief must have heard.

There was a bow from that individual, and Ibrahim went on about his master and lord feeling now, of all times in his life, how painful it was that he, the learned young Hakim, could not thank his highness in words for the protection given to him when he was pursued by those degenerate sons of Shaitan. He would have liked to thank the Emir verbally, but as he could not do this he had come himself to ask his n.o.ble friend to accept a trifling gift, because he knew how great a lover he was of horses, and if he would condescend to accept the little present and place it upon his favourite steed it might bring his grateful friend sometimes before his eyes.

There was a piece of pantomime here. The Baggara chief looked puzzled, and when Ibrahim paused he looked up. Then he looked down, and had to ask the old Sheikh what he meant, being quite unable to notice what everyone else in the courtyard could see plainly, till it was almost touched.

Then, and then only, did he cast aside all his formal Arabic, Eastern stateliness and a.s.sume a rapturous expression, seizing one of the reins, examining it closely, raising the scarlet-dyed, drooping plume, touching the bit and broad band with its silver ornamentation, and uttering exclamations of delight the more impressive from their being to a great extent real, for the gift was a worthy one and such as any lover of a horse would appreciate.

Then followed a warm burst of thanks, and a request that the Hakim's friend would descend and enter the house for refreshment.
