"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?"
