The elder doctor left in charge heard the words, and answered them, addressing himself, not to Mr. Engelman, but to me. He caught me by the arm, as I was leaving the room in my turn.
"Poison!" the doctor whispered in my ear. "Keep it a secret; that's what he means."
I ran to my own bedchamber and bolted myself in. At that one word, "Poison," the atrocious suggestion of Frau Meyer, when she had referred to Doctor Fontaine's lost medicine-chest, instantly associated itself in my memory with Madame Fontaine's suspicious intrusion into Mr. Keller's room. Good God! had I not surprised her standing close by the table on which the night-drink was set? and had I not heard Doctor Dormann say, "That's unlucky," when he was told that the barley-water had been all drunk by the patient, and the jug and glass washed as usual? For the first few moments, I really think I must have been beside myself, so completely was I overpowered by the horror of my own suspicions. I had just sense enough to keep out of Mr. Engelman's way until I felt my mind restored in some degree to its customary balance.
Recovering the power of thinking connectedly, I began to feel ashamed of the panic which had seized on me.
What conceivable object had the widow to gain by Mr. Keller's death? Her whole interest in her daughter's future centered, on the contrary, in his living long enough to be made ashamed of his prejudices, and to give his consent to the marriage. To kill him for the purpose of removing Fritz from the influence of his father's authority would be so atrocious an act in itself, and would so certainly separate Minna and Fritz for ever, in the perfectly possible event of a discovery, that I really recoiled from the contemplation of this contingency as I might have recoiled from deliberately disgracing myself. Doctor Dormann had rashly rushed at a false conclusion—that was the one comforting reflection that occurred to me. I threw open my door again in a frenzy of impatience to hear the decision, whichever way it might turn.
The experiment had been tried in my absence. Mr. Keller had fallen into a broken slumber. Doctor Dormann was just closing the little bag in which he had brought his testing apparatus from his own house. Even now there was no prevailing on him to state his suspicions plainly.
"It's curious," he said, "to see how all mortal speculations on events, generally resolve themselves into threes. Have we given the emetic too late? Are my tests insufficient? Or have I made a complete mistake?" He turned to his elder colleague. "My dear doctor, I see you want a positive answer. No need to leave the room, Mr. Engelman! You and the young English gentleman, your friend, must not be deceived for a single moment so far as I am concerned. I see in the patient a mysterious wasting of the vital powers, which is not accompanied by the symptoms of any disease known to me to which I can point as a cause. In plain words, I tell you, I don't understand Mr. Keller's illness."
It was perhaps through a motive of delicacy that he persisted in making a needless mystery of his suspicions. In any case he was evidently a man who despised all quackery from the bottom of his heart. The old doctor looked at him with a frown of disapproval, as if his frank confession had violated the unwritten laws of medical etiquette.
"If you will allow me to watch the case," he resumed, "under the superintendence of my respected colleague, I shall be happy to submit to approval any palliative treatment which may occur to me. My respected colleague knows that I am always ready to learn."
His respected colleague made a formal bow, looked at his watch, and hastened away to another patient. Doctor Dormann, taking up his hat, stopped to look at Mother Barbara, fast asleep in her easy chair by the bedside.
