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.
As soon as they sallied out below they saw that Lionel and the men with him had captured a prisoner; and just as they joined the party the guard came round from the other side of the warehouse, bringing with them the crossbow, its bolt, and the pistol. The prisoner, whose shoulder was broken by Roger Browne's shot, was at once taken to Captain Vere's quarters. That officer had just arrived from the walls, knowing the time at which the capture would probably be made.
"So you have succeeded," he said. "Well done, lads; you have earned the thanks of all. We will take this man at once to the governor, who is at present at the town hall."
By the time they issued out quite a crowd had assembled, for the news that William Von Arnig had been brought a prisoner and wounded to Captain Vere's quarters had spread rapidly. The crowd increased as they went along, and Captain Vere and his party had difficulty in making their way to the town hall, many of the people exclaiming loudly against this treatment of one of the leading citizens. The governor was, when they entered, holding council with the English leader, Sir Roger Williams.
"Why, what is this, Captain Vere?" he asked in surprise as that officer, accompanied by the two boys and followed by Roger Browne and Job Tredgold guarding the prisoner, entered.
"I have to accuse this man of treacherously communicating with the enemy," Francis Vere said.
"What?" Arnold de Groenvelt exclaimed in surprise. "Why, this is Mynheer
