It was then half-past eleven, as he found by looking at his watch, and too late to go to sleep again, even if he felt inclined.

Precisely half an hour later a figure appeared at the door of the tent, and a voice observed quietly: "Time to wake up, mastel. You tellee me wake you one piecee time twelluf. Twelluf now, and me welly sleepy."

It was Ling.

CHAPTER FOUR.

BETRAYED.

Frobisher scrutinised the Korean's face closely, but there was no shadow of change in its Oriental impa.s.sivity. For all that the man's bearing betrayed, he might never have moved from his post since the camp had been pitched; yet the young Englishman could not rid himself of the suspicion that Ling was not exactly what he appeared to be. Moreover, now that the man was standing inside the tent, Frobisher again became conscious of a faint suggestion of the odour of sandal-wood oil.

However, it would not in any way suit his plans to betray his suspicions of the Korean at present, therefore he merely contented himself with remarking quietly:

"Very well, Ling. You had better get to sleep, so as to be rested by the morning; and I'll wake you as soon as it is time to break camp and be stirring. By the way, I fancied I heard someone prowling about my tent half an hour ago. I suppose you did not notice anything out of the common, or you would have reported it to me at once, eh?"

"Me no undelstand 'anything outel le common', mastel; what mastel mean?"

enquired Ling, his almond-shaped eyes opening in apparent puzzlement.

"I mean," replied Frobisher, rather testily--for he now felt almost convinced that the fellow was trying to hoodwink him--"that I suppose you are quite sure that no spy, no one belonging to the enemy, in fact, approached or entered the camp while I was asleep and you were on guard?"

"Oh!" exclaimed Ling, his face breaking out into a smile, "I undelstand now. No, mastel; n.o.body not come neal camp. If anyone had come he would be dead by now; me shoot any stlangel quick, without ask any questions."

"All right!" answered Frobisher, permitting himself to be almost persuaded against his better judgment that the man was honest, so absolutely child-like and bland was his manner; "get away to your own quarters and secure as much sleep as you possibly can, for we have a long march before us to-morrow." And he turned away, to show Ling that his presence was no longer required.

But at the moment of turning he could almost have sworn that he caught sight of Ling's lips parted in a sardonic smile. Frobisher wheeled again immediately, but when he once more looked at the man, the Korean's face was as indifferently emotionless as though carved from stone, and Murray was compelled to acknowledge that the expression which he thought he had noticed must have been due to the flickering shadows cast by the lantern that he carried in his hand.

Thus dismissed, Ling trotted off and threw himself down beside the inner wheels of one of the carts, covered his face with a fold of his ample cloak, and was, to all outward appearance, fast asleep on the instant.

Frobisher, after regarding the rec.u.mbent form for a long minute or more, silently tiptoed away to his post of observation, having reached which, he extinguished the lantern, making sure, first of all, that his matches were ready to hand in his pocket, so that the light might not prove a convenient target for any prowling sharpshooter of the enemy.

He remained motionless in the one position for at least half an hour, and then, beginning to feel a trifle cramped from his spell of inactivity, made up his mind to traverse the sleeping camp, in order to a.s.sure himself fully that all was as it should be. Leaving the lantern behind him, he made his way slowly and silently, by the dim light of the stars, round the sleeping bivouac. And it was not until he had completed the entire circ.u.mference of the circle and was back again at his starting-point, that it occurred to him that he had not particularly noticed Ling, who, of course, ought to have been lying asleep where Frobisher had left him.

At once the Englishman's dormant suspicions again awoke into full activity, and, lighting the lantern, he proceeded to repeat his investigation, going his rounds in the opposite direction this time; and, sure enough, when he came to the place where he had left Ling lying, the spot was vacant--Ling had disappeared.

"Now what in the world is the explanation of this?" Frobisher asked himself testily. "I'm certain there is something fishy about the fellow, and I would give a trifle to be able to discover what game it is that he's playing. Where, in the name of Fortune, has he got to now, I wonder?"

As the thought pa.s.sed through his mind he heard a sudden, suspicious sound right on the other side of the camp. The idea it conveyed to him was that a man had tripped or fallen over something; and this suggestion was strengthened when, immediately afterward, certain low muttered words in the Korean tongue, which sounded remarkably like a string of hearty expletives, issued from the same quarter. And the voice was undoubtedly that of Ling.

Frobisher whipped the revolver out of his pocket and leapt like a deer in the direction of the sound, arriving on the spot just in time to discover Ling sitting upright on the dewy gra.s.s, alternately rubbing his head and his shins. The Englishman stood looking down at the other for a few moments, and in that brief interval found time to notice that his feet were soiled and plastered with fresh clay, which had certainly not been on them when Frobisher had left him half an hour previously. It was also certain that he could not have acc.u.mulated that clay within the confines of the camp, for the s.p.a.ce where the wagons had been drawn up was carpeted entirely with gra.s.s, and there was no vestige of clay anywhere within the circle. Frobisher therefore felt more convinced than ever that Ling was something very different from what he represented himself to be.

"Well, Ling," he remarked sternly, after a pause, during which the Korean had been vigorously rubbing himself, "what's happened to you?

Where have you been; what have you been doing?" And as he spoke he brought his right hand slightly forward, so that the rays of light from the lantern which he carried fell upon the gleaming barrel of his revolver.

Ling observed the motion, and shrank back guiltily. "Oh, mastel," he quavered, "me thinkee me heal a sound ovel hele--fol me too flightened to sleep--and me come hele to see what the mattel."

"What kind of sound did you think you heard?" queried Frobisher, looking the man square in the eyes.

Ling tried to return the gaze, but failed. His almond-shaped eyes met the other's for a few seconds, and then turned ground-ward.

"Me believe me heal someone moving ovel hele," he replied, "and so me came see if anybody tly to get in."

"Then what did you fall over?" asked Frobisher.

"Me go look see if anybody hiding outside camp," explained Ling glibly, "and me fall ovel shafts of calt coming back. Me no see clealy without lanteln," he continued, volubly.

"If you believed you heard a movement," said Frobisher, "why didn't you come and tell me, instead of going yourself? Besides, it seems strange that you, who ought to have been sleepy after your spell of duty, should have noticed those suspicious sounds, while I, who was wideawake, heard nothing."

"No undelstand, mastel," said Ling, regarding Frobisher with a blank stare.

"No, you scoundrel!" retorted Frobisher angrily; "you only understand just what suits you, don't you? However, understand this, my fine fellow," he went on, bringing the revolver into full view, and shaking it in front of the now thoroughly frightened Korean; "if I find that you've been up to any tricks, I'll shoot you, as sure as my name's what it is, so you had better be very careful. Do you understand that? Very well, then; get over to your place and lie down; and mark this--don't let me catch you slinking about this camp any more to-night. Savvee?"

"Me savvee plenty, mastel," replied Ling, gathering himself up and hobbling away. He added some other words in his own language, in a tone that sounded anything but rea.s.suring; but as Frobisher was totally unfamiliar with the Korean tongue, he was compelled to let the matter pa.s.s unnoticed.

The remainder of the night slipped away without interruption. But shortly after the incident above referred to, Frobisher noticed that the stars were becoming obscured, and about two o'clock in the morning rain began to fall, softly at first, then increasing in volume until, in half an hour after the beginning, it seemed as though the very bottom had fallen out of the heavens, and thus allowed the water pent up there to fall upon the earth in an overwhelming cataract.

One by one, as they became chilled by the wet, the sleepers awoke, and crawled drowsily either into or beneath the carts; and soon Frobisher was the only human being in sight anywhere in camp. He was quickly drenched to the skin, but realising how excellent a screen for rushing the camp this downpour would make, he remained at his post, shivering with cold, for the rest of the night; and by the time that morning dawned, was feeling weary and wretched.

As soon, however, as the first hint of dawn paled the eastern sky, the rain ceased as suddenly as it had begun, and Frobisher aroused Ling and gave him orders to call the men to their breakfast, so that an early start might be made.

When Frobisher poked his head under the hood of the cart where the Korean had taken refuge from the rain, he somehow very strongly suspected that that individual had been awake and sitting up at the moment of his approach; yet he was obliged to shake the man vigorously for a full minute before he could be made to comprehend that it was time to bestir himself.

As soon as Ling permitted himself to realise this fact, however, he sprang from the cart with an admirable a.s.sumption of briskness, and soon had the mule-drivers at work preparing breakfast and inspanning the wet and wretched-looking mules. He even took the trouble to light a fire himself and prepare a cup of hot tea for the "mastel", for which the drenched and shivering young Englishman felt sincerely grateful.

The young man had taken only a single sip, however, when he detected a very peculiar taste in the liquid, and spat the mouthful out on to the ground, with an exclamation of disgust. Happening to glance upward at the moment, he caught sight of Ling regarding him with a peculiar expression, in which hate, cunning, and satisfaction were curiously mingled; and Frobisher could scarcely repress his anger as he realised the meaning of that malignant glare. Not content with having attempted to murder him by means of the knife during the night, the scoundrel was now trying to put an end to him by means of poison; a powerful and very painful poison, too, surmised Frobisher, if he might judge by the burning, biting sensation that tingled on his throat, lips, and tongue.

It was not Frobisher's policy, however, to let Ling see that he was suspected, otherwise the man might become desperate and adopt some still more strenuous measure, which it might be difficult if not impossible to frustrate. Therefore, forcing back the words of indignation and accusation that leapt to his lips, and making a strong effort to command his voice so that it might not quiver, he remarked quietly: "Hi, Ling!

This tea is very strong. You've forgotten to put in any sugar. I suppose there is some, isn't there?"

Ling repressed a smile, dived under one of the cart hoods, and presently reappeared with a few lumps of the required sweetening, which Frobisher calmly dropped into his cup, stirring them round so as to dissolve them completely. He then set the cup down beside him, as though to let the liquid cool, and watched Ling keenly until that wily Oriental was looking another way, when he quickly capsized the contents of the cup on to the gra.s.s, where the liquid was immediately absorbed by the damp earth.

When Ling returned for the cup Frobisher observed him closely, and could not avoid noticing the expression of satisfaction which even the man's usual impa.s.sivity failed to suppress completely. Frobisher was by this time quite convinced that Ling was a traitor, either belonging to, or in the pay of, the Government party; and he began to wonder whether, after all, the man had spoken the truth when he had affirmed that Korean troops were approaching to capture the caravan along the Yong-wol road.

Might not the very reverse be the fact, and the troops be hiding in ambush along the very road that they were about to traverse? Frobisher was almost inclined to take the risk of altering the course of the caravan in order to regain the main road; but a few seconds'

consideration caused him to abandon that idea. There were no less than four roads to Yong-wol, including the customary route, and the Englishman had only selected the one they were on at the last moment before starting--after the arrival of Ling from the ship, in fact; so that, unless Ling had arranged to have messengers waiting for him ash.o.r.e, and had found means to communicate with them--which Frobisher could scarcely believe possible--the route they were taking could hardly have leaked out. He therefore made up his mind to stand by his original plan; and, the men having finished their meal, he gave orders for the caravan to proceed, himself leading the way and keeping a sharp look-out for any sign of treachery on the part of the Korean.

It was but a short distance to the banks of the stream, previously mentioned, which crossed the route of the caravan, but when they arrived there a disagreeable surprise was in store for the leader. The heavy rain of the previous night had swollen the river to such an extent that, instead of a placid, shallow stream, little exceeding in size a mere brook, it was now a roaring, foaming torrent, rising higher and higher every minute; and there was no knowing how long it might be before the water would subside to its normal level. Frobisher consequently realised with dismay that he might be compelled to stay where he was for several days, allowing the enemy ample time to arrive on the spot and capture the caravan.

Evidently, he told himself, it would never do to be delayed by this obstacle; but how was he to overcome it? that was the question.

"Ling," he demanded, "how long will it be before this water will go low enough to allow us to cross?"

The Korean shrugged his shoulders. "Me no know, mastel," he said.

"Pelhaps by to-night; pelhaps not fol week. No can do nothing, can only stop hele."

"Don't you believe that for a minute, my man," retorted Frobisher tartly, for it annoyed him to observe the calm satisfaction with which the Korean regarded the situation. "We've got to get across, do you hear? And we are going to do it; so make up your mind to that. If I have to drown every man of the caravan, and you too," he added, "I'm going to manage it somehow, so you understand. And now that I've told you this, tell me in return whether there is any other place beside this where we can cross?"

"No, mastel," said Ling, "no othel place. This only place anywhele.

And no can closs hele, mastel can see fol himselluf."

"Well," said Frobisher determinedly, "if this is the only place, this is where we cross. The river is rising very rapidly, and the longer we delay the worse it will be; you see, therefore, that there's no time to waste. I'm going to ride in to find how deep the water is, and, what's more, my friend, you are coming with me." As he spoke, the young sailor grasped the bridle of Ling's mule, dug his heels into his own animal's sides, and together the Englishman and the now thoroughly frightened Korean descended the steep bank and plunged into the river.
