There my servant was in wait for me, according to my bidding. I took him to my room, and setting the round shot before him, commanded him to examine it. He was a handy fellow, and had the rudiments of more trades than one. It was not long before he discovered, in the surface of the iron, a knob or boss, exceeding small, the which being touched, a narrow channel was revealed, wherein lay a short tube of the thickness of a finger. "’Tis good locksmith’s work, sir," he said with admiration, putting the tube into my hand. I looked therein, and discovered a small roll of paper, the which, upon my spreading it out, I saw was covered with writing in the Spanish tongue, and in the very hand of Volmar, but with no name either at head or at foot. I read the writing with a vast curiosity and eagerness, and what I read was this— "_The victuals will last but one week longer. One of my foes will be hanged; the Englishman I go about to remove. Attack the wall over against the market. I vouch that in ten days the city will yield._" Here was proof of as pretty a piece of villainy as the mind of man could conceive. Verhoeff was to be hanged; I myself to be removed; the wall over against the market was that which the Burgomaster had in charge, and the attack was to be directed thereupon with the intent to harass him and bring him to a frame of mind meet for surrender. A pretty plot indeed, and one that I rejoiced to have the means of circumventing. I dismissed my servant and sat myself down to consider my ways. ’Twas necessary to my purpose that Volmar should be utterly confounded. I could brook no chance of his wriggling out of the full exposure of his guilt. Wherefore it seemed to me inexpedient that I should at once carry the traitorous letter to the council, for he had many friends therein, whom he might easily persuade that the writing was but a cunning imitation of his own, done by myself out of the despite and enmity I bore him; nor indeed could I explain how I had come by the paper, but by owning that I had gone from the city without authority, a thing he would find means to twist to my disadvantage. The end of my cogitation was that I resolved still to bide my time, not doubting that within the week something would happen to point my road clearly.
