Retreat, after he was once clear of the walls, had naturally never entered his mind. But now he would have been glad enough to have been able to return to his cell unobserved. It would be intensely humiliating to be obliged to wait there, in the small space between the door and the glass-sown path, until his jailer arrived, some twenty-four hours later, to release him. Yet there seemed to be no alternative.
How careless, how criminally foolish he had been to allow himself to be trapped by so transparent a device! thought Frobisher. He ought to have suspected a trap directly he discovered that his boots had been removed, and he might have known that such jailers as he was dealing with do not leave cell doors unlatched by accident, or leave keys to open other doors hanging on walls in conspicuous places, just where an escaping prisoner would be most likely to see them. How those pirates would laugh and jeer at him on the morrow, when they arrived and found him there, shivering with the bitter cold of night in that climate, at that time of year! The mere thought of such humiliation caused Frobisher to grit his teeth with anger, and he had almost made up his mind to chance a quick dash across that cruel barrier, trusting that he would not injure himself so severely as to make escape absolutely impossible, when something occurred which caused him quickly to change his mind, and made him shrink back into the shadow of the door, pressing himself up into one of the corners, to avoid observation and consequent discovery, if possible.
He had caught sight of the figure of a Chinaman emerging from the shadow of the jungle which surrounded the fort on its landward side. The man’s figure stood out plain and clear-cut in the moonlight, which was so bright that Frobisher could easily distinguish his every movement, could even see how the man was dressed; and he wondered what the fellow could be doing there at that time of night.
In that part of northern China, especially at that season, men do not wander about in the jungle at night, or indeed at any other time, if they can help it, having a very natural objection to being caught and eaten by prowling, hungry tigers; and it was therefore not a little strange that this man should arrive at the fort by that way, particularly as it could be reached much more easily by the road which the pirates had constructed for their own convenience. It would almost appear as though the man bad come by this route in order to avoid the pirates’ observation; and the longer Frobisher considered the matter, the more certain did he become that this was actually the case, and the more he wondered what the reason might be.
The man had only stood in full view for a few brief seconds, just long enough to convince the Englishman that he was real, and not a figment of his own heated imagination. Then he had stepped back quickly into the shadow of the jungle, crouching down beside a clump of bamboo, where he was so well concealed from observation that Frobisher could just distinguish the outline of his stooping body. Indeed, had he not kept his eyes on the man the whole time, it would have been impossible to detect his hiding-place, so well did the colour of his clothing blend with the vegetation which formed his background.
The Englishman’s heart began to beat with excitement and hope, for a thousand possibilities at once presented themselves to him. It was morally certain that the hiding man could have no connection with the pirates, or he would have come forward boldly and demanded admittance; and if not a friend of, or connected with the outlaws, he must necessarily be opposed to them. Ah! if it were only possible to attract the man’s attention without also attracting that of the pirates, escape should be a simple matter, thought Frobisher. He was already practically as good as outside the walls, and all that was necessary was that something should be laid down on the top of the glass over which he could walk without cutting his feet, and the thing was done; he could be miles beyond the possibility of pursuit before morning broke, if only the preliminaries could be put in hand immediately.
It did not take him long to decide that he would make the attempt to attract the man’s attention. If the latter were a friend, and the attempt were crowned with success, all would be well, and he would be free within an hour; while if the man should after all prove to be an enemy—well, he might as well be discovered and taken back to prison now, as wait all night in the cold. One thing was quite certain—without outside assistance escape was impossible; so he decided to put his fortune to the test and risk his freedom, if not his life, upon the turn of the die.
With this idea, he drew his handkerchief from his pocket and was about to step forward and wave it, when he saw a movement among the clump of bamboo, and the next instant the Chinaman rose to his feet and ran like a deer toward the very part of the fort in which Frobisher’s cell was situated. He ran noiselessly, on his toes, and bent almost double in the effort to make himself as small as possible. And he did not slacken speed until he had reached the walls of the fort, where he again crouched down in the shadow, almost directly under the window of Frobisher’s cell, about twenty yards away from the spot where the Englishman himself was concealed.
The latter, in the face of this new move, determined to watch a few minutes longer before revealing himself, and kept his eyes on the crouching figure with the greatest interest. Was the man going to prove friend or foe, rescuer or would-be assassin? Scarcely the latter, the Englishman thought, for there seemed something strangely familiar in the man’s movements and in his whole appearance; and Frobisher experienced the sensation of having met, or seen, this man somewhere before, though under what circumstances he could not for the life of him recall. He was something of the same build as Ling; but Ling, he knew, was dead, for he had seen the man’s body. Then, again, he might pass at a distance for Quen-lung, the interpreter; but from what Frobisher had already seen of that person, he did not for a moment believe that Quen-lung was at all the kind of man to risk his skin on a midnight excursion to a pirate stronghold.
Suddenly Frobisher’s attention was disturbed by the sound of a very low whistle, undoubtedly proceeding from the Chinaman. That whistle was beyond question a signal of some sort, and was just as certainly intended for himself. To hesitate longer would have been the height of folly, for the longer the delay now, the greater would be the danger of discovery; so, putting his fingers in his mouth, Frobisher replied with another whistle in exactly the same key and tone as the Chinaman’s. The latter leapt to his feet, took a few steps backward, and looked up at the window; but seeing nothing there, he proceeded to glance round him anxiously.
