"These men were Tito Balzani and Roger de Horn?" questioned Amalric sternly.

"Yes; and soon I became aware that they were engaged upon other matters than those which directly concerned me, and that I was to be made useful to them in the practice of their evil arts. I will not speak too much of these things. The thought is hateful and repulsive. Suffice it to say that they were eagerly pursuing the study of certain black arts, and that they had books and instruments, either belonging to Tito, or found by them in this strange tower, whereby they sought to prosecute their studies. They had dupes too, who visited them, and strove to peer into the future, and they would use incantations and burn strange pungent drugs, and methinks they ofttimes so bewildered their visitors that they imagined they saw in the smoke wreaths strange things which were never there at all. However that may be, there were some who came again and again, and brought gold with them each time. And as the conjurors grew bolder they would ask larger fees. I trow they have grown rich upon the proceeds of those weeks of fraud and devilry."

"And how didst thou come to hear and see so much?"

"They grew careless of my presence in the upper chamber, where everything was prepared. As I grew weak from hunger and from loss of blood—for blood seemed a necessity to them for every experiment, and it was part of their purpose to reduce me to a mere shadow—they spoke freely of all they did and wished to do. I am certain they never intended me to escape their clutches; and I believe that upon the night of the rescue, had you been but a few minutes longer in forcing the door, they would have taken my life without pity, so fearful were they of what I might reveal. But they could not spare time in their haste to collect their gold, and as it was, they were almost caught as they climbed through the window-slits."

"And was it real magic?" asked Alys in a low voice; "or was it all trickery and jugglery?"

"That is hard to tell," answered Hugh; "but methinks they did all in their power to invoke the aid of the Evil One. I trow well that they sought to throw me into trances, that I might aid them in this. They studied their books, and tried their wicked spells upon me; and there were moments when I felt them succeeding, albeit I fought might and main. If I could keep my mind fixed on holy things, and continue to pray, I was safe from them. But there were moments when I was so weak that I felt my hold slipping away, and I trow that then I did fall in some sort beneath some evil spell; and the horror of it is but passing away now, since Brother Angelus has spoken and prayed with me. Trickery there was in much they did. I know my face was shown again and again in the magic mirror, and that I was dressed up to look sometimes as a maid, sometimes as an aged man, sometimes as a mailed warrior—my face painted and my hair arranged to suit the part. This was when I was wellnigh dead through loss of blood, and could not resist them. They had gained such power over me that ofttimes I could not make a sound, greatly as I longed to do so. When I guessed, from what they had said in my hearing, that Linda was to be brought to see my face in the mirror, I strove might and main to cry aloud, and tell who and what these men were; but my voice would not obey—no sound could I utter."

"If we can but catch them," cried Amalric, "they shall pay for their devilries!"

But Roger and Tito were too wary to be caught. They had fled beyond the precincts of Oxford, and pursuit was abandoned at last as hopeless. Hugh recovered his wonted vigour with more rapidity than could at first have been anticipated; but he showed no disposition to return to his old quarters at Dagville's Inn. Once he asked after Linda, and on hearing what had befallen her he heaved a long sigh.

"Methinks that I have brought her nothing but woe and sorrow," he said; "she will be happier there than in the tumult of this strange city. Some day I will see her again; but for the present let her remain in peace and safety. I am glad she should be in so tranquil a place."

But the house of the Balzanis had lost its charm for him. He had no wish to face the father of Tito or the witcheries of Lotta, of which he was not unconscious.
