"May we see Dr. von Stein?" asked Parker. "If he is in?"
"I will ask the Herr Doktor if he iss in," replied the man, stiffly.
"Dummkopf!" roared a voice from inside the house. An instant later man and dog shrank back along the hall and there appeared in their place one of the most striking personalities Allen Parker had ever seen.
Dr. Friedrich von Stein was inches more than six feet tall and he stood perfectly erect, with the unmistakable carriage of a well drilled soldier. He was big boned, but lean, and every movement was made with military precision. More than any other feature his eyes impressed Parker: they were steady, penetrating, and absolutely black. But for a thread of gray here and there his well-kept beard and hair were black. He might have been any age from forty to sixty, so deceptive was his appearance.
"Come in, if you please," he said, before Parker could speak. Von Stein's voice was rich and deep, but with a metallic quality which somehow corresponded with his mechanical smile. Except for the guttural r's there was hardly a hint of the foreigner in his speech. "It is Mr. and Mrs. Parker, I believe? I am Dr. von Stein."

He stood aside for them to pass into the hallway, and while they murmured their thanks he shot a volley of German at the man, whom he called Heinrich. The frightened servant vanished; and the Parkers were taken into a living room furnished carelessly, but in good enough taste. Betty took her place on a couch, to which the doctor led her with a bow. Parker sank into an overstuffed chair not far from a window.
"I learned your names because of the beauty of madame," said Von Stein, as he stood looming above the mantel. Again he bowed. "One could not see her without wishing to know how such a charming woman was called. You are my neighbors from down the street, I believe."
"Yes," replied Allen. He wanted to be agreeable, but found it difficult. "And I think Mrs. Parker has developed a great admiration for you. She persuaded me to come here to-day. Are you, by chance, a psycho-analyst? I don't even know that you are a doctor of medicine, but – "
"I know a very great deal about the human mind," interrupted Dr. von Stein calmly. "I know a great deal about many things. I am not going to practice medicine here in Pine Hills because I have research work to do, but I will help you if I can. What is your trouble?"

The question brought back to Parker the mood of half an hour ago. Almost savagely he snapped the portfolio open and spread out a few of his recent drawings, with some of the earlier ones for comparison.
"Look!" he cried. "These vicious things are what I am doing now! I can't help myself! The pencil does not obey me! Apparently I have no emotional control. It's as though my normal ideas were shouldered aside, like people in a crowd. And my writing to-day was as bad as these illustrations. I'm doing a book. Consider these things carefully, Doctor. They are not obscene, except by inference. They can't be censored. The book would go through the mails. Yet they are deadly! Look at my heroine in these two pictures. In one she is like – like violets! In the other she looks capable of any crime! What is she? A vampire, if there is such a thing? A witch? I can almost believe in demonology since I made these last drawings!"
Parker, in spite of his excitement, tried to read the face of Dr. Friedrich von Stein. He found nothing but the automatic smile upon that mask. Yet it seemed to the artist that this time there was a hint of real pleasure in the curve of the lips. Was it possible that anyone could like those drawings? Parker began to think that he was going insane.
"This is most unfortunate for you," rumbled the doctor. "I understand. But I trust that the condition can be remedied, if it persists. You, Mr. Parker, and you, Madame, do you understand something of physics, of psychology, of metaphysics?"
"I fear that I'm rather ignorant," answered Betty. "Certainly I am in comparison with a man of your attainments."

Dr. von Stein bowed. He turned his black eyes upon Parker.
"And you, sir? I must adjust my explanation to – what shall I say? To your knowledge of the higher reaches of scientific thought?"
"Why, I majored in philosophy in college," said Parker, hesitatingly. "But that's quite a time ago, Herr Doktor. Of course I've tried to keep up with the conclusions of science. But a writer or a painter doesn't have any too much opportunity. He has his own problems to concern him."
"Yes, indeed!" Dr. von Stein was thoughtful. "So, and especially for the benefit of madame, I shall speak in terms of the concrete."
"Please consider me stupid!" begged Betty. "But I want to understand!"
"Certainly, except that you are not stupid, Madame. I will proceed. Both of you, I assume, know something of the radio? Very good! You know that an etheric wave transmits the message, and that it is received and amplified so that it is within the range of the human ear. These waves were there when paleolithic man hunted his meat with a stone-tipped club. To use them it was necessary to invent the microphone, and a receiving instrument.
"What I have said you already know. But here is what may startle you. Human thought is an etheric wave of the same essential nature as the radio wave. They are both electrical currents external to man. Thoughts sweep across the human mind as sound currents sweep across the aerials of a radio – "
"I told you!" Allen Parker turned a triumphant face to his wife. "Pardon me, Herr Doktor! I have tried to convince Mrs. Parker that my idea came from outside!"

"Exactly!" Dr. von Stein took no offense. "And a difference between the mind and the radio set is that with the radio you tune in upon whatever you choose, and when you choose. The mind is not under such control, although it should be. It receives that to which it happens to be open. Or that thought which has been intensified and strengthened by having been received and entertained by other minds. In India they say: 'Five thousand died of the plague and fifty thousand died of fear.' Do you both follow me?"
It was unnecessary to ask. Betty sat on the edge of the couch, intent upon every word. Parker, although more restrained, was equally interested. Moreover he was delighted to have what he had felt instinctively confirmed, in a way, by a man of science.
"Herbert Spencer said," continued the doctor, "that no thought, no feeling, is ever manifested save as the result of a physical force. This principle will before long be a scientific commonplace. And Huxley predicted that we would arrive at a mechanical equivalent of consciousness. But I will not attempt to bolster my position with authorities. I know, and I can prove what I know.
"You, Mr. Parker, have been receiving some particularly annoying thoughts which have been intensified, it may be, by others, or another. Human will power can alter the rate of vibration of the line of force, or etheric wave. So-called good thoughts have a high rate of vibration, and those which are called bad ordinarily have a low rate. Have you, perhaps, an enemy?"
"Not that I know of," replied Parker, in a low voice.
"Then it would follow that this is accidental."

"Cood heavens! Do you mean to say that someone could do this to me maliciously?"
"So far my experiments leave something to be desired," said Dr. von Stein, without answering directly. "No doubt you are peculiarly susceptible to thoughts which bear in any way on your work."
"But isn't there any help for it?" asked Betty. She was regarding her husband with the eyes of a stranger.
"I believe I can do something for Mr. Parker."
There was a knock at the door. The doctor boomed an order to come in. Heinrich, with the dachshund at his heels, entered bearing a tray with a bottle of wine and some slices of heavy fruit cake. He drew out a table and placed the tray.
"Do not bring that dog in when I have guests," said Von Stein. He spoke with a gleam of white teeth. "You know what will happen, Heinrich?"
"Ja, Herr Doktor! I take Hans oudt!" The man was terrified. He gathered the dog into his arms and fairly fled from the room. Dr. von Stein turned with a smile.
"I have to discipline him," he explained. "He's a stupid fellow, but faithful. I can't have ordinary servants about. There are scientific men who would be willing to bribe them for a look at my laboratory."
"I did not know such things were done among scholars," said Betty, slowly.
"What I have accomplished means power, Madame!" exclaimed the doctor. "There are jackals in every walk of life. If an unscrupulous man of science got into my laboratory, a physicist for instance, he might … find out things!"

Dr. von Stein turned to his duties as host. He filled their glasses, and watched with satisfaction Betty's obvious enjoyment of the cake. A box of mellow Havanas appeared from a cabinet: imported cigarettes from a smoking stand. But Parker, in spite of a liking for good wine and tobacco, was far too much concerned about his work to forget the errand that had brought him there.
"So you think," he said, when there was opportunity, "that you can help me, Dr. von Stein?"
"I can," replied von Stein, firmly; "but before attempting anything I'd like to wait a day or two. The attacking thoughts may become less violent, or your resistance greater, in either of which cases the condition will fade out. You will either get better or much worse. If you are worse come to see me again, and I promise you that I will do something!"
"I'll come, and thank you!" Parker felt better, and more cheerful than he had since the beginning of the disturbance. "Few things could make me suffer so much as trouble with my work."
"That is what I thought," agreed Dr. von Stein.
