in the rigid attitude of his body.
Charnock heard a faint sound higher up the lane. The sound became louder and defined itself. It was the slap-slap of a pair of Moorish slippers. Charnock drew Hamet back by the trunk of a tree, which sheltered them both from the view of anyone who came down the hill. He left the lane free, and into the open space there came a man who wore the dress of a Moor of wealth, serwal, chamir, farajia, and haik, spotless and complete. In figure he was slight and perhaps a trifle under the middle height, and the haik was drawn close over his forehead to shield him from the sun.
Hassan was seated in the dust with the sun beating full upon his head. In front of him the newcomer stopped. "Peace be with you," he said, as Charnock, who had some knowledge of Arabic, understood. But the beggar made no answer, nor gave any sign that he heard. He sat motionless, impassive, a secret figure of stone.
The newcomer laughed lightly to himself, and the laughter, within view of the rags and misery of the once rich man, sounded unpleasant and callous. Hamet shifted a foot at Charnock's side, and Charnock, whose interest in this picturesque encounter was steadily growing, pressed a hand upon the boy's shoulder to restrain him.
The stranger, however, had noticed neither of the two spectators. He was still laughing softly to himself as he watched the beggar, and in a little he began to hum between his teeth a tune--a queer, elusive tune of a sweet but rather mournful melody; and it seemed to Charnock by some indefinable hint of movement that Hassan Akbar was straining his ears to catch and register that tune.
The stranger advanced to Hassan and dropped a coin in his lap. The coin was not copper, for it sparkled in the air as it fell. Then with another easy laugh he turned to go down into Tangier. But as he turned he saw Charnock watching him. On the instant his hand went to his hood and drew it close about his cheeks, but not before Charnock had seen a scared face flashed at him for a moment, and immediately withdrawn. The Moor went down the lane.
"Perhaps it was he who told?" said Charnock.
Hamet disagreed.
"He would not know. His beard was fair, so he comes from Fez." Charnock, too, had remarked that the man was fair-haired. But nevertheless this encounter of the rich Moor and the beggar remained in his thoughts, and he allowed his imagination lazily to fix a picture of it in his mind. Thus occupied, he walked through the cemetery, taking in that way a short cut to the Sôk. But he was not half-way across the cemetery when he turned sharply towards Hamet.
"Do you remember the tune the Moor hummed?"
Charnock's ear was slow to retain the memory of music. Hamet, however, promptly whistled the melody from beginning to end, while Charnock stood and took count of it.
"I shall have forgotten it to-morrow," said Hamet.
"I think now that I shall recollect it tomorrow," said Charnock, and he walked on.
But in a moment or two he stopped again as though some new perplexity was present to his mind.
"Hamet," he said, "before the Moor appeared at all, while his footsteps were still faint, certainly before he spoke, Hassan Akbar stopped his prayer, which you say he never stops. He knew then who was coming. At all events he suspected. How did he know? How did he suspect?"
"There is the Sôk," replied Hamet.
They had passed round the bend of the hill up which the cemetery slopes, and were come within view of the market-place. Charnock was puzzled by his unanswered question, and the question was forced to his notice again that afternoon, and with yet greater force.
It was market-day. Charnock beheld stretched out beneath him a great field, or rather a great plain, (for the grass was long since trampled into mud,) which curved down to the yellow sun-baked wall of the city, and whereon an innumerable throng, Negroes from Timbuctoo, Arabs, Jews, and Moors, in all manner of raiment, from rags to coloured robes, jostled and seethed, bawled and sweated, under a hot sun and in a brilliant air. Here an old hag screamed aloud the virtues of her merchandise, a few skinny onions and vegetables; there two men forced a passage with blows of their sticks, and behind them a stately train of camels brought in from the uplands their loads of dates. A Riffian sauntered by with an indifferent air, his silver-mounted gun upon his back, a pair of pistols in his belt, and a great coarse tail of hair swinging between his shoulders. He needed no couriers to prepare his way. At one spot a serpent-charmer thrust out his tongue, from which a snake was hanging by the fangs; at another a story-teller, vivid in narration, and of an extraordinary aptness in his gestures, held an audience enchained. From every side the din of human voices rose into the air, and to the din was added the snarling of camels, the braying of donkeys, the bleating of sheep, the lowing of oxen, and all manner of squeals and grunts, so that it seemed the whole brute creation had combined to make one discordant orchestra.
Into this Babel Charnock descended.
"Those are the shoemakers," said Hamet. He pointed to a cluster of tiny grimed gunny-bag tents in a corner of the highest part of the Sôk. In the doorways of the tents a few men sat cobbling; one or two wood fires crackled in the intervals between the tents; and in close proximity a dead mule took its last unsavoury sleep.
"Hassan Akbar sleeps in the mud near to the tents," continued Hamet. "Every evening he comes down to the Sôk, buys milk and bread from the shoemakers, and sleeps--"
"Near to that mule!" interrupted Charnock. "And he was the richest man in all Tangier."
A moment later there was shown to him the second picture which he was to carry away from Tangier. Down the Sôk, through the crowd, came the Moor, in his spotless robes, and a few yards behind him, striding swiftly and noiselessly, the blind gaunt beggar of the cemetery gate followed upon his trail. In and out amongst the shifting groups he threaded and wound, and never erred in his pursuit. The man in whose track he kept never spoke when all were shouting, yet Hassan never faltered. The sound of his footsteps was lost in a multitude of the like sounds, yet Hassan was somehow sensible of it, somehow to his ears it emerged distinct.
Charnock was amazed; in a way too he was chilled. It seemed uncanny that this sightless creature of the impassive face should be able to follow, follow, follow relentlessly, unswervingly, one silent man amongst the noisy hundreds. Charnock walked for a few yards by Hassan Akbar's side, keeping pace with him. Even with his eyes fixed upon the Moor in front, even though he saw his feet tread the ground, he could not distinguish his footfalls. How then could Hassan?
Tracker and Tracked passed from the Sôk under the archway of the gate, and Charnock dismissing Hamet walked down towards his hotel near the waterside. However, he missed his road. He turned through the horse market, descended the steep street, past the great Mosque, and walked along a narrow, crooked alley between blank and yellow walls, which ended in a tunnel beneath over-arching houses. Almost within the mouth of this tunnel there was a shop, or so it seemed, for a stuffed jackal swung above the door as a sign. Before this shop Charnock halted with a thrill of excitement. The door of the shop was shut, the unglazed window was shuttered. It was not on that account that Charnock stopped; but underneath the shuttered window, his head almost touching the sill, Hassan squatted on the cobbles fingering now and then a silver dollar.
Inside the door a bolt grated, the door opened, and a stout, undersized European appeared in the entrance, polished a pair of glasses, set them upon his nose, glanced up and down the street, closed the door behind him, and taking no heed whatever of the blind man under his window, walked briskly into the tunnel. He walked with a short, tripping, and jaunty step.
Charnock waited while the echo of it diminished and ceased, and the moment it had ceased he saw Hassan, without any hurry, without any sign of expectation or excitement, rise slowly to his feet and move along the house wall towards the door. His right elbow scraped the plaster; then his elbow touched nothing. He had come to the recess of the door, and he stopped.
It flashed upon Charnock that he had not heard the bolt again grate into its socket. The door was then only latched and--was Hassan's quarry behind its panels?
The affair had ceased to be a toy with which Charnock's imagination could idly play. He strode across the alley and
