"Most likely the man is using the crossbow on purpose to avoid attracting the attention of the Spaniards, Geoffrey. At this distance they could not see the crossbow, while a puff of smoke would be sure to catch their eye."
"There, he has shot again. I did not see the quarrel fall in the moat. See, one of the Spanish soldiers from that battery is coming forward. There, he has stooped and picked something up. Hallo! do you see that? He has just raised his arm; that is a signal, surely."
"It certainly looked like it," Lionel agreed. "It was a sort of half wave of the hand. That is very strange!"
"Very, Lionel; it looks to me very suspicious. It is quite possible that a piece of paper may have been tied round the bolt, and that someone is sending information to the enemy. This ought to be looked to."
"But what are we to do, Geoffrey? Merely seeing a Spanish soldier wave his arm is scarcely reason enough for bringing an accusation against anyone. We are not even sure that he picked up the bolt; and even if he did, the action might have been a sort of mocking wave of the hand at the failure of the shooter to send it as far as the battery."
"It might be, of course, Lionel. No, we have certainly nothing to go upon that would justify our making a report on the subject, but quite enough to induce us to keep a watch on this fellow, whoever he may be. Let us see, to begin with, if he shoots again.
They waited for an hour, but the head of the crossbow was not again thrust out of the window.
"He may have ceased shooting for either of two reasons," Geoffrey said. "If he is a true man, because he sees that his bolts do not carry far enough to be of any use. If he is a traitor, because he has gained his object, and knows that his communication has reached his friends outside. We will go down now and inquire who is the occupier of the next warehouse."
The merchant himself was not below, for as he did business with other towns he had had nothing to do since Sluys was cut off from the surrounded country; but one of his clerks was at work, making out bills and accounts in his office as if the thunder of the guns outside was unheard by him. The boys had often spoken to him as they passed in and out.
"Who occupies the warehouse on the right?" Geoffrey asked him carelessly.
"William Arnig," he replied. "He is a leading citizen, and one of the greatest merchants in our trade. His cellars are the most extensive we have, and he does a great trade in times of peace with Bruges, Ghent, Antwerp, and other towns."
"I suppose he is a Protestant like most of the townspeople?" Geoffrey remarked.
"No, he is a Catholic; but he is not one who pushes his opinions strongly, and, he is well disposed to the cause, and a captain in one of the city bands. The Catholics and Protestants always dwell quietly together throughout the Low Countries, and would have no animosities against each other were it not for the Spaniards. Formerly, at least, this was the case; but since the persecutions we have Protestant towns and Catholic towns, the one holding to the States cause, the other siding with the Spaniards. Why do you ask?"
"Oh, I hadn't heard the name of your next neighbour, and, was wondering who he might be."
The boys had now been nearly two months in Holland, and were beginning to understand the language, which is not difficult to acquire, and differed then even less than now from the dialect spoken in the eastern counties of England, between whom and Holland there had been for many generations much trade and intimate relations.
"What had we better do next, Geoffrey?" Lionel asked as they left the warehouse.
"I think that in the first place, Lionel, we will take our post at the window tomorrow, and keep a close watch all day to see whether this shooting is repeated. If it is, we had better report the matter to Captain Vere, and leave him to decide what should be done. I do not see that we could undertake anything alone, and in any case, you see, it would be a serious matter to lay an accusation against a prominent citizen who is actually a captain of one of the bands."
Upon the following day they took their post again at the window, and after some hours watching saw three bolts fired from the next window. Watching intently, they saw the two first fall into the moat. They could not see where the other fell; but as there was no splash in the water, they concluded that it had fallen beyond it, and in a minute they saw a soldier again advance from the battery, pick up something at the edge of the water, raise his arm, and retire. That evening when Captain Vere returned from the ramparts they informed him of what they had observed.
"Doubtless it is an act of treachery," he said, "and this merchant is communicating with the enemy. At the same time what you have seen, although convincing evidence to me, is scarce enough for me to denounce him. Doubtless he does not write these letters until he is ready to fire them off, and were he arrested in his house or on his way to the warehouse we might fail to find proofs of his guilt, and naught but ill feeling would be caused among his friends. No, whatever we do we must do cautiously. Have you thought of any plan by which we might catch him in the act?"
"If two or three men could be introduced into his warehouse, and concealed in the room from which he fires, they might succeed in catching him in the act, Captain Vere; but the room may be an empty one without any place whatever where they could be hidden, and unless they were actually in the room they would be of little good, for he would have time, if he heard footsteps, to thrust any letter he may have written into his mouth, and so destroy it before it could be seized."
"That is so," Captain Vere agreed. "The matter seems a difficult one, and yet it is of the greatest importance to hinder communications with the Spaniards. Tonight all the soldiers who can be spared, aided by all the citizens able to use mattock and pick, are to set to work to begin to raise a half moon round the windmill behind the point they are attacking, so as to have a second line to fall back upon when the wall gives way, which it will do ere long, for it is sorely shaken and battered. It is most important to keep this from the knowledge of the Spaniards. Now, lads, you have shown your keenness by taking notice of what is going on, see if you cannot go further, and hit upon some plan of catching this traitor at his work. If before night we can think of no scheme, I must go to the governor and tell him frankly that we have suspicions of treachery, though we cannot prove them, and ask him, in order to prevent the possibility of our plans being communicated to the enemy, to place some troops in all the warehouses along that line, so that none can shoot there from any message to the Spaniards."
Just as Captain Vere finished his supper, the boys came into the room again.
"We have thought of a plan, sir, that might succeed, although it would be somewhat difficult. The dormer window from which these bolts have been fired lies thirty or forty feet away from that from which we were looking. The roof is so steep that no one could hold a footing upon it for a moment, nor could a plank be placed upon which he could walk. The window is about twelve feet from the top of the roof. We think that one standing on the ledge of our window might climb on to its top, and once there swing a rope with a stout grapnel attached to catch on the ridge of the roof; then two or three men might climb up there and work themselves along, and then lower themselves down with a rope on to the top of the next window. They would need to have ropes fastened round their bodies, for the height is great, and a slip would mean death.
"The one farthest out on the window could lean over when he hears a noise below him, and when he saw the crossbow thrust from the window, could by a sudden blow knock it from the fellow's hand, when it would slide down the roof and fall into the narrow yard between the warehouse and the walls. Of course some men would be placed there in readiness to seize it, and others at the door of the warehouse to arrest the traitor if he ran down."
"I think the plan is a good one, though somewhat difficult of execution," Captain Vere said. "But this enterprise on the roof would be a difficult one and dangerous, since as you say a slip would mean death."
"Lionel and myself, sir, would undertake that with the aid of two active men to hold the ropes for us. We have both done plenty of bird nesting in the woods of Hedingham, and are not likely to turn giddy."
"I don't think it is necessary for more than one to get down on to that window," Captain Vere said. "Only one could so place himself as to look down upon the crossbow. However, you shall divide the honour of the enterprise between you. You, as the eldest and strongest, Geoffrey, shall carry out your plan on the roof, while you, Lionel, shall take post at the door with four men to arrest the traitor when he leaves. I will select two strong and active men to accompany you, Geoffrey, and aid you in your attempt; but mind, before you try to get out of the window and to climb on to its roof, have a strong rope fastened round your body and held by the others; then in case of a slip, they can haul you in again. I will see that the ropes and grapnels are in readiness."
The next morning early Geoffrey proceeded with the two men who had been selected to accompany him to his usual lookout. Both were active, wiry men, and entered fully into the spirit of the undertaking when Geoffrey explained its nature to them. They looked out of the dormer window at the sharp roof slanting away in front of them and up to the ridge above.
"I think, Master Vickars," one of them, Roger Browne by name, said, "that I had best go up first. I served for some years at sea, and am used to climbing about in dizzy places. It is no easy matter to get from this window sill astride the roof above us, and moreover I am more like to heave the grapnel so that it will hook firmly on to the ridge than you are."
"Very well, Roger. I should be willing to try, but doubtless you would manage it far better than I should. But before you start we will fasten the other rope round your body, as Captain Vere directed me to do. Then in case you slip, or anything gives way with your weight, we can check you before you slide far down below us."
A rope was accordingly tied round the man's body under his arms. Taking the grapnel, to which the other rope was attached, he got out on to the sill. It was not an easy task to climb up on to the ridge of the dormer window, and it needed all his strength and activity to accomplish the feat. Once astride of the ridge the rest was easy. At the first cast he threw the grapnel so that it caught securely on the top of the roof. After testing it with two or three pulls he clambered up, leaving the lower end of the rope hanging by the side of the window. As soon as he had gained this position Geoffrey, who was to follow him, prepared to start.
According to the instructions Browne had given him he fastened the end of the rope which was round Browne's body under his own shoulders, then leaning over and taking a firm hold of the rope to which the grapnel was attached, he let himself out of the window. Browne hauled from above at the rope round his body, and he pulled himself with his hands by that attached to the grapnel, and presently reached the top.
"I am glad you came first, Roger," he said. "I do not think I could have ever pulled myself up if you had not assisted me."
He unfastened the rope, and the end was thrown down to the window, and Job Tredgold, the other man, fastened it round him and was hauled up as Geoffrey had been.
"We will move along now to that stack of chimneys coming through the roof four feet below the ridge on the town side," Geoffrey said. "We can stand down there out of sight of the Spaniards. We shall be sure to attract attention sitting up here, and might have some bullets flying round our ears, besides which this fellow's friends might suspect our object and signal to him in some way. It is two hours yet to the time when we have twice seen him send his bolts across the moat."
This was accordingly done, and for an hour and a half they sat down on the roof with their feet against the stack of chimneys.
"It is time to be moving now," Geoffrey said at last. "I think the best way will be for me to get by the side of the dormer window instead of above it. It would be very awkward leaning over there, and I should not have strength to strike a blow; whereas with the rope under my arms and my foot on the edge of the sill, which projects a few inches beyond the side of the window, I could stand upright and strike a downright blow on the crossbow."
"That would be the best way, I think," Roger Browne agreed; "and I will come down on to the top of the window and lean over. In the first place your foot might slip, and as you dangle there by the rope he might cut it and let you shoot over, or he might lean out and shoot you as you climb up the roof again; but if I am above with my pistol in readiness there will be no fear of accidents."
CHAPTER V
AN HEROIC DEFENCE
The plan Roger Browne suggested was carried out. Geoffrey was first lowered to his place by the side of the window, and bracing himself against its side with a foot on the sill he managed to stand upright, leaning against the rope that Job Tredgold held from above. Job had instructions when Geoffrey lifted his arm to ease the rope a few inches so as to enable the lad to lean forward. After two or three attempts Geoffrey got the rope to the exact length which would enable him to look round the corner and to strike a blow with his right hand, in which he held a stout club. Roger Browne then descended by the aid of the other rope, and fastening it round his body lay down astride of the roof of the window with his head and shoulders over the end, and his pistol held in readiness.
It seemed an age to Geoffrey before he heard the sound of a footstep in the loft beside him. He grasped his cudgel firmly and leaned slightly forward. For ten minutes there was quiet within, and Geoffrey guessed that the traitor was writing the missive he was about to send to the enemy; then the footstep approached the window, and a moment later a crossbow was thrust out. A glance at it sufficed to show that the bolt was enveloped in a piece of paper wound round it and secured with a string. Steadying himself as well as he could Geoffrey struck with all his force down upon the crossbow. The weapon, loosely held, went clattering down the tiles. There was an exclamation of surprise and fury from within the window, and at the same moment Job Tredgold, seeing that Geoffrey's attempt had been successful, hauled away at the rope and began to drag him backward up the tiles.
The lad saw a man lean out of the window and look up at him, then a pistol was levelled; but the report came from above the window, and not from the threatening weapon. A sharp cry of pain was heard, as the pistol fell from the man's hand and followed the crossbow down the roof. A few seconds later Geoffrey was hauled up to the ridge, where he was at once joined by Roger Browne. Shifting the ropes they moved along till above the window from which they had issued. Geoffrey was first lowered down. As soon as he had got in at the window he undid the rope and Job Tredgold followed him, while Roger Browne slid down by the rope attached to the grapnel; then they ran downstairs.
