By England's Aid; Or, the Freeing of the Netherlands, 1585-1604. G. A. Henty

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. To-night all the soldiers who can be spared, aided by all the citizens able to use matlock 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 therefrom 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 cross-bow 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."
