She leaned forward in her chair, her always pale face assuming a new pallor. Laying her hand upon her husband's, she asked in a quick, excited manner:
"Do you know how Frontier died?"
"I know he died suddenly; now you speak of it, I have an idea it was a case of felo de se. You know I was in Munich at the time."
"Arthur," Edith said earnestly, "I have never told even you; but I saw Frontier die. I had a pass-key to his studio, and his private rooms were just behind it. That night I went in on my way from dinner—Uncle Peter and I had been dining together, and I left him at the door with the carriage—after a study I'd forgotten. We were going to Rome the next morning, and I didn't want to leave it. The picture was at the further end of the studio, and as I went down the room I heard voices and saw that Frontier's door was open. He sat at a table with a tiny wine-glass in his hand. A man who stood back to me said, just as I came within hearing: 'It is none of my affair, and I shall not interfere; but you'll allow me to advise you not to be rash.' I could not hear Frontier's answer, partly because I paid no attention, of course never suspecting the truth. But as I went towards my easel, Frontier, hearing the noise, I suppose, and afraid of being interrupted, caught up the glass and drank what was in it. The other man sprang forward just in time to catch him as he fell back, and it suddenly came over me that he was taking poison. I cried out and ran into the room, but it seemed only an instant before it vas all over. Oh, it was terrible, Arthur, terrible!"
She covered her agitated face with her hands, as if to shut out the vision which rose before her. Her husband sat in silent astonishment, a conviction growing in his mind of whom the other witness of Frontier's death must have been.
"Arthur," Edith broke out suddenly, "that man was no better than a murderer. He let Frontier kill himself. When I cried out, 'Oh, why didn't you stop him!' he said as coolly as if I had asked the most trivial question, 'Why should I? What right had I to interfere?' It was terrible! He seemed to me a perfect fiend!"
"It was—who was it?" demanded her husband, a name almost escaping him in his excitement.
"It was Dr. Ashton; the man who is coming to sit down at your table to-night. Arthur, I cannot meet him! I knew when he came to our reception that I had seen him before, but I could not tell where. There is his ring now. Let me get by you!"
"But where are you going?" Fenton asked in amazement.
"To my room. Any where to get out of his way."
