Tring laughed, low but maliciously. “So that is where your courage lies,” he answered. “That is the crown of valor that you boast in exploring the wonders of the unknown world. Come,” he added after a minute, as if changing his tactics in dealing with this man who was now thoroughly in his power, or so he thought, “come and put a better complexion upon things; we are already past the hardest stretch of the road—if there is to be found the solution to that problem upon which we both have spent so much time, it will be found so much the more readily now because of the sacrifices that we have already made for it. Are the trances tiring you beyond endurance?”

The alchemist let his head sink into his hands. “I am tired—I am tired,” was all that he could say.

Tring regarded him with disgust, but held back the angry words which sprang to his lips and expressed himself more gently.

“Then if there is a fault it must lie with you, Pan Kreutz,” he said. “It is beyond my understanding that such a man as you should find exhaustion in these simple experiments that I have performed. Many another person I have put into trances similar to yours, and for longer periods of time, too, and there has been no harm, nay, nor physical exhaustion from it.”

“Alas,” the alchemist moaned as if making a confession, “I have been in trances other than those of your making, and almost continually, too.”

“What?” Tring leaped to his feet in astonishment. “What do you say? You have been in trances induced by others? Other men share our secrets, then? Who may it be that is also a master of this rare craft? I had thought that no others, save I, in this town were able to bring about such trances.” He glared at Kreutz with open hatred and let his fingers stray as well to the handle of a short knife that he carried in his belt, for although he was but a young man, he took his occult powers very seriously. There was as well an element of fear in his emotions, since the civil authorities of that day dealt usually in short and severe fashion with persons brought before magistrates on the charge of indulging in dark or occult practices. Death even was prescribed as punishment for some, although disfiguring, whipping, stocks, and banishment were the most common penalties.

Tring’s powers, though mysterious in those days, could be easily explained in ours. The so-called trances into which certain persons have the power to send others we call in these times merely hypnotic sleep. Hypnotism in the days when all men and women were to an extent superstitious was looked upon as one of the very worst works of a malignant devil upon earth. Tring possessed to some extent the ability to summon hypnotic sleep to a willing patient, and the alchemist had become a too willing patient in his endeavor to discover the secret that Tring had made appear so desirable.

And as is the case with most practitioners of hypnotism and their subjects, the hypnotist had gained, little by little, more and more power over his co-worker, until in a few months the alchemist had become merely a tool in the hands of Tring, who, knowing his ability and scholarly accomplishments, did not hesitate to use them for his own ends. He did this, however, with great caution, and enjoined ever upon the alchemist the need for the utmost secrecy, for if it had become known that such tricks were being practiced, the law would make short shrift of both.

“No man,” answered the wretched alchemist, “no man, but perhaps—devils!”

“Devils?” Tring stood motionless, thunderstruck. Was the alchemist losing his mind?
