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.
When I went abroad next day I perceived that black care had seized upon the people. The scarcity of victuals was known of all, and as the meaner folk felt the pinch of hunger more dearly they broke forth into murmurs and complaints. Dark looks were cast upon me as I took my way to the council chamber, and still darker met me there. Mindful of Volmar's intent to have me removed, I looked for some instant charge to be brought against me, as though I were a Jonah in the city; but nought was said openly, and I concluded that I must be on my guard against some secret machination—a knife in my back, or a stray bullet did I but show myself upon the ramparts. I was heedful, therefore, that day and the days succeeding, to go only in the middle of the street, and to keep within the house after nightfall, not deeming it any mark of valour to jeopardize the happiness of three good folk and the safety of the city by running into any needless danger.
As day followed day, I became aware that the people's discontent and queasiness was being fomented by the agents of Volmar, though that two-faced villain was most fervent, at the meetings of the council, in admonishing the burghers to endure to the end. Day after day the Spaniards plied their artillery upon the walls, chiefly upon that portion where the Burgomaster was in charge of the defences. The masonry was sore battered, many of the burghers were slain or maimed, and the Burgomaster himself, who endeavoured still to sustain the reputation he had achieved in that night sally, was struck upon the elbow by a fragment of stone, whereby the little man was afflicted more heavily in mind than in body. In his one ear, so to speak, Volmar whispered counsels of despair under a mask of encouragement; in the other I spoke words of comfort and good cheer, assuring him that, could he but resist a little longer, Prince Maurice would come to his succour, as he had promised. My influence, I knew, was sapped by Volmar's guileful insinuations, and I could not doubt that finally I should be worsted unless I could prove Volmar to be the traitor he was.
As the straits of the citizens waxed more grievous, secret messengers were sent forth, to implore aid of Sir Francis Vere and of Prince Maurice; but these men never delivered their messages, as was afterwards discovered, and doubtless Volmar had found means to acquaint the Spaniards with their errand, albeit by means that never came to light. Though I kept as good a watch upon him as I could, and my servant did likewise, we could not find him out in aught that would give us a handle against him, and with the passing of time I grew discomfortable in mind, fearing lest Jan Verhoeff's ten days' respite should slip away before I had my proofs ready. And I was the more uneasy because I perceived that the ill-will of the burghers towards me increased and spread day by day. Their good favour, which I had at the first procured by my diligence in assisting the defence, had now given place to mistrust and malignity, fostered by Volmar's minions; and I knew that this canker was eating ever more deeply into the souls of the populace.
VII
On the night of Saturday, a device came into my mind whereby I might bring the truth to light in a manner that could not be gainsaid. It was high time, for a great assembly of the citizens had been holden that day, whereat sundry burghers of good standing openly advised that terms should be made with the enemy. There wanted but three days of the period set by Volmar for the surrender of the city, and on the Monday morning Jan Verhoeff was to die. At this assembly, when I essayed to speak to the people, there arose a great uproar in one quarter of the square, where I perceived certain of Volmar's creatures to be gathered. Amid the clamour I heard cries of "Spy!" "Traitor!" and sundry other scandalous appellatives; and a stone being cast at me, the Burgomaster commanded me to withdraw out of the throng, lest a general riot should ensue. Therefore, I say, it was high time I did somewhat, and a device came in happy hour into my mind.
To perform it I must needs make an accomplice, albeit unwitting, of the Captain of the Guard. He was a man of a most steadfast courage, diligent in his duty, a staunch friend to me, and one that would never yield to the enemy save at the uttermost extremity: a pattern of that loyalty and stubborn valour whereby his nation has won liberty and immortal fame; a man withal simple of soul, as witness his belief in the astrological foolery whereof I have made mention. I resolved to turn this very simplicity to account.
I repaired to his house, where he was supping after the fatigues of the day, and after reminding him that the next day was Sunday, I declared that I had discovered a flaw in Mynheer Volmar's talisman. I affected to have a certain skill in reading the stars, and my study of the heavens had shown me that the customary Sunday truce could only be assured by firing a shot of silver, instead of an iron ball as was wont.
"I thank you, sir," said he, accepting my statement with the faith of a child. "We must acquaint Mynheer Volmar withal; for there is but little time to make the silver shot before the Sabbath breaks."
"By your good favour, sir," said I, "this matter must be held a secret 'twixt us two. By the opposition of Jupiter with Mars, and the quartility of Saturn with Venus, I apprehend that the imparting of this matter to any wight whatsoever save only yourself will let loose upon us and the city a myriad evil influences, and all the good we may have of it will be utterly undone."
