While she was still wondering thus, replying from time to time to Montalvo in monosyllables, the sledge in front of them turned the corner of one of the eastern bastions and came to a halt. The place where it stopped was desolate and lonely, for the town being in a state of peace no guard was mounted on the wall, nor could any living soul be found upon the snowy waste that lay beyond the moat. At first, indeed, Lysbeth was able to see nobody at all, for by now the sun had gone down and her eyes were not accustomed to the increasing light of the moon. Presently, however, she caught sight of a knot of people standing on the ice in a recess or little bay of the moat, and half hidden by a fringe of dead reeds.

Montalvo saw also, and halted his horse within three paces of them. The people were five in number, three Spanish soldiers and two women. Lysbeth looked, and with difficulty stifled a cry of surprise and fear, for she knew the women. The tall, dark person, with lowering eyes, was none other than the cap-seller and Spanish spy, Black Meg. And she who crouched there upon the ice, her arms bound behind her, her grizzled locks, torn loose by some rough hand, trailing on the snow—surely it was the woman who called herself the Mare, and who that very afternoon spoke to her, saying that she had known her father, and cursing the Spaniards and their Inquisition. What were they doing here? Instantly an answer leapt into her mind, for she remembered Black Meg’s words—that there was a price upon this heretic’s head which before nightfall would be in her pocket. And why was there a square hole cut in the ice immediately in front of the captive? Could it be—no, that was too horrible.

“Well, officer,” broke in Montalvo, addressing the sergeant in a quiet, wearied voice, “what is all this about? Set out your case.”

“Excellency,” replied the man, “it is a very simple matter. This creature here, so that woman is ready to take oath,” and he pointed to Black Meg, “is a notorious heretic who has already been condemned to death by the Holy Office, and whose husband, a learned man who painted pictures and studied the stars, was burnt on a charge of witchcraft and heresy, two years ago at Brussels. But she managed to escape the stake, and since then has lived as a vagrant, hiding in the islands of the Haarlemer Meer, and, it is suspected, working murder and robbery on any of Spanish blood whom she can catch. Now she has been caught herself and identified, and, of course, the sentence being in full force against her, can be dealt with at once on your Excellency’s command. Indeed, it would not have been necessary that you should be troubled about the thing at all had it not been that this worthy woman,” and again he pointed to Black Meg, “who was the one who waylaid her, pulled her down and held her till we came, requires your certificate in order that she may claim the reward from the Treasurer of the Holy Inquisition. Therefore, you will be asked to certify that this is, indeed, the notorious heretic commonly known as Martha the Mare, but whose other name I forget, after which, if you will please to withdraw, we will see to the rest.”

“You mean that she will be taken to the prison to be dealt with by the Holy Office?” queried Montalvo.

“Not exactly, Excellency,” answered the sergeant with a discreet smile and a cough. “The prison, I am told, is quite full, but she may start for the prison and—there seems to be a hole in the ice into which, since Satan leads the footsteps of such people astray, this heretic might chance to fall—or throw herself.”

“What is the evidence?” asked Montalvo.

Then Black Meg stood forward, and, with the rapidity and unction of a spy, poured out her tale. She identified the woman with one whom she had known who was sentenced to death by the Inquisition and escaped, and, after giving other evidence, ended by repeating the conversation which she had overheard between the accused and Lysbeth that afternoon.

“You accompanied me in a fortunate hour, Señora van Hout,” said the captain gaily, “for now, to satisfy myself, as I wish to be just, and do not trust these paid hags,” and he nodded towards Black Meg, “I must ask you upon your oath before God whether or no you confirm that woman’s tale, and whether or no this very ugly person named the Mare called down curses upon my people and the Holy Office? Answer, and quickly, if you please, Señora, for it grows cold here and my horse is beginning to shiver.”

Then, for the first time, the Mare raised her head, dragging at her hair, which had become frozen to the ice, until she tore it free.
