"Climb up, sah!" came the eager whisper.
Tom grasped the rod, set his feet upon the knobby bole, and with exertions which strained the muscles of arms and legs to the verge of cramp he heaved himself into the leafy bough. The figure there clutched him as he was on the point of falling. "Sah! sah!" it said with a sob of joy. Tom gripped Mbutu's hand, and sat for a minute breathless, peering down towards the circle of sleeping negroes. The wind blew with increasing force, rustling the leaves, and the branch swayed heavily, grazing the hut's thatched roof.
"No time fink, sah," said Mbutu. "Must run away!"
But now that he was free Tom had recovered his wits, and saw that if he was to get clear away he must exercise all his cunning. There was the hut in which the chief, his enemy, lay; there were the guards, sleeping, it was true, but likely to wake at any moment. Around was the village, filled with Arabs, Manyema, and slaves; an alarm would set hundreds of men on the alert, and there was but a slender chance of escaping from so many. Beyond the village, three hundred yards away, was the thin outer belt of the forest; could he but gain that, Tom thought, he might hide and elude pursuit. There was danger from wild beasts, no doubt; but a wild beast was less dangerous than the vengeful Portuguese. It must be a dash for life and liberty, he saw. How was he to escape immediate danger of detection?
His quick eye noticed that Mbutu wore the burnous and turban of an Arab. With a leaping heart he saw in a flash of thought his way made plain. It involved manifold risks. "Never venture never win," he said to himself, and proceeded to put his plan into operation. Tying the knife again to the rod, but at an angle to form a crook, he let it down, and hooked up the severed cords that lay at the foot of the tree. He swiftly knotted them to form two strong ropes. Then bidding Mbutu secure the knife and follow him, he crept cautiously along the bough towards the hut. The wind was stiffening to a gale; the horned moon was dipping behind the forest, and the hut lay in shadow. He came to the end of the branch, and crawled on to the roof, Mbutu following close. Moving only when the swaying bough rustled against the thatch, drowning all other sounds, he made his way cat-like across the roof, reached the edge, slid over, and slipped noiselessly down one of the wooden posts supporting the thatch at the distance of a foot from the wall of the hut. He was on the ground on the side farthest from the tree. For some moments he stood and listened. There was a sound of voices not far to his right, and he thought he detected a low murmur from two or three quarters. Evidently there were many still awake. Tom decided that the plan he had formed offered a better chance of escape than a mere dash for the forest. Taking off the turban with which he had been provided by the hakim, he opened it out, and folded the sheet of linen over and over until it made a long tight roll. In a few whispered words he explained his plan to Mbutu; then, signing to the boy to come after him quietly, he crept through one of the holes in the wall, and found himself inside the hut. On a rude table a small rushlight was burning, by whose glimmer he saw the chief stretched upon his back on a narrow plank, his burnous cast aside, his long form covered with a red blanket. He was fast asleep, with his mouth open, his breath coming and going with long soundless heaves. With heart beating violently in spite of himself, Tom stole behind the Arab, and then whispered to Mbutu that he was to hold the man's head when he gave the signal. Both then stooped; Tom gave a nod; Mbutu pressed the chief's head down firmly with both hands, and at the same instant Tom stuffed the rolled turban into his mouth, and knotted it beneath his neck. He wriggled and half rose upon his elbow; instantly Mbutu's arms were thrown around him, and he was pulled backward and held in a firm grip. Tom had meanwhile run to his feet, and, whipping one of the lengths of cord from his pocket, he swiftly tied the chief's ankles together. Now that it was impossible for the Arab to stand, Tom bade Mbutu assist him. There was a short struggle, the Arab striving to wriggle out of Mbutu's grasp. It was in vain; with the remaining cord Tom bound the Arab's arms together, and in five minutes after their entrance the chief lay securely gagged and bound.
Without losing a moment Tom donned the Arab's burnous and turban.
"Do you know the nearest way to the forest?" he asked Mbutu.
The Muhima nodded, and Tom told him that, relying upon his disguise, he was going to walk boldly through the camp. If they met anyone, Mbutu was to address him in his own tongue in such a way as to disarm suspicion. Tom reckoned on his own height to enable him to pass for the chief. There was a box of matches by the rushlight; he put that in his pocket, caught up a small bag of nuts that lay beside the Arab, and without bestowing another glance on the prostrate form, whose eyes were glaring at him with all the fury of impotent rage, he walked slowly out of the hut, Mbutu a yard behind.
They went quickly, stepping in the shade of the huts. Their way led past the hut in which the Portuguese was sleeping. The African native is sensitive to the slightest tremor of the ground, and one of the negroes who had accompanied De Castro, and was acting as sentry over him, crouching over a watch-fire, heard the footfall of the two fugitives, and came round the hut towards them. He dimly saw, as he supposed, the tall form of the Arab chief stalking by, accompanied by one of his men. He stepped back, and at the same moment Mbutu, with a power of mimicry that surprised his master, addressed him in a few quiet words, bidding him keep good watch over the señor, while Tom walked on with a dignified air, as though the negro were beneath his notice. When out of the man's sight they quickened their steps. They reached the outer circle of huts, evaded the watch-fires placed at intervals, crossed the fence and ditch, and, breaking into a run, plunged into the dense bush at the edge of the compound. The fugitives had barely gone two hundred yards when they heard a great outcry in the camp behind. One of the eight guards had awoke and rekindled the dying fire. Glancing at the tree, he discovered that the prisoner was gone. He roused his companions, and with mutual upbraidings they began to dispute who should venture to inform the chief of the escape. Their voices rose in altercation, and De Castro's sentry, hearing the noise, came to see what had happened. As soon as he knew that the Englishman had escaped, he ran to his master's hut, whence in a moment issued the Portuguese, swearing great oaths at being disturbed when he so much needed rest, and for the moment not understanding what his man said. A glance at the tree apprised him that his anticipated victim had escaped his clutches. Heedless of the news that the chief had but just before been seen walking through the camp, he rushed to the hut, and finding Mustapha there bound and gagged, began with frantic haste and fearful imprecations, in which he could not refrain from mingling taunts, to cut him free. Both men were beside themselves with fury. The whole camp was by this time alarmed, and Arabs and Manyema alike cowered before the wrath of their infuriated superiors. De Castro ran wildly about crying for torches, while Mustapha ordered every man in the camp to set off in search of the escaped prisoner, and despatched parties in all directions. He went himself to the hakim's hut, believing that the Arab seen walking in the prisoner's company must be Mahmoud and no other. Meeting the grave physician as he came out to enquire the reason of the uproar, the chief roundly accused him of effecting or conniving at the release of the Englishman. The hakim's face showed neither surprise nor pleasure; he was as coldly imperturbable as ever. Quietly denying that he had had any hand in the escape, he asked the Arab what he expected to gain by wild ill-directed searches in the dark; the torches and the din would only give warning to the fugitives, and help them to elude pursuit. Mustapha saw the absurdity of his proceedings, and chafed under the cynical scorn of the physician, whose calling and character enforced his unwilling respect. Turning on his heel, he ordered drums to be beaten to recall the search-parties, and enquiry to be made for the traitor in the camp; and when De Castro came up to him, foaming with passion and shouting that the whole thing had been planned to spite him, Mustapha bade him keep a still tongue in his head, or he would find himself in the Englishman's place. It wanted still more than three hours to sunrise, and giving orders that the search should be diligently resumed at dawn, the chief returned to his hut.
In the meantime the outcry had at first caused the fugitives to hasten their steps; but, fearing that the rustle and crash of their progress through the bush would arrest the pursuers' attention, they dropped behind a fallen tree. Not many minutes afterwards a party of Manyema who had outstripped the rest, keeping close together in their mutual fear, came within a few yards of Tom's hiding-place. There was one moment of suspense, then they passed on with torches burning; but soon the tap-tap of the recalling drums sounded through the wood, and they turned, passed within a few paces of where the panting fugitives lay crouched, and retraced their steps to the camp.
