"'Tis a case of grievous perplexity," said he, "and I am sore distraught. If he have sworn his very soul to her, as this rhyme doth seem to intimate, I am miserably afflicted for his case. Doubtless 'tis some snare which hath unwillingly been thrown about him. Nevertheless, I will diligently and warily address myself to the task, and Heaven grant us a safe deliverance. Yet I freely own there is both danger and extremity in the attempt. She will doubtless appear and claim the fulfilment of his pledge. But I must cope with her alone; none else may witness the conflict. It is not the first time that I have battled with the powers of darkness."

"But what motive hath she for this persecution? it is not surely out of sheer malice," said the dame, weeping.

"Belike not," replied Dee, thoughtfully. "It doth savour of those incantations whereof I oft read in divers tractates, whereby she expects to gain advantage or deliverance if she sacrifice another victim to the demon whereunto she hath sold herself. Indeed, we hear of some whose tenure of life can only be renewed by the yearly substitution of another; and it is to this possible danger that our feeble efforts must be directed. But I trust in aid stronger than the united hosts of the Prince of Darkness. This very night, I doubt not, will come the final struggle."

The wind was now still, but ever and anon bursts of hail hurtled on the window. Thunder growled in the distance, waxing louder and louder, until its roar might have appalled the stoutest heart.

With many anxious wishes and admonitions the distressed parents left the Doctor to himself.

He took from his pocket an hour-glass, a bible, and a Latin translation from the Arabic, being a treatise on witches, genii, demons, and the like, together with their symbols, method of invocation, and many other subjects equally useful. Intent on his studies, he hardly looked aside save for the purpose of turning the glass, when he immediately became absorbed as before.

Now and then he cast a glance towards the bed. His patient lay perfectly quiet, but the Doctor fancied he was listening.

About midnight he heard a groan; he shut his book, and, looking aside, beheld the terrible eye and aspect of the Red Woman glaring fiercely upon him. She had, in all likelihood, been concealed somewhere within hearing; for a closet door, on one side of the chamber, stood open as though she had just issued from it.

With great presence of mind he adjured her that she should declare her errand.

"I am here on my master's business; mine errand concerns not thee," was the reply. Her terrible eyes glanced, as she spoke, towards the bed where the unfortunate Gervase Buckley lay writhing as though in torment.
