This was some time after the critical moment had passed, and there were in the room Mrs. Dayton, the landlady, Dr. Holmes, the nurse, and myself. At the utterance of these words we all felt ashamed and cast looks of increased interest at the poor girl.
She was very lovely. Though without means, and to all appearance without friends, she possessed in great degree the charm of winsomeness, and not even her many sufferings, nor the indignation under which she was then laboring, could quite rob her countenance of that tender and confiding expression which so often redeems the plainest face and makes beauty doubly attractive.
"Dr. Holmes does not know you," I hastened to say; "I do, and utterly repel for you any such insinuation. In return, will you tell me if there is any one in the world whom you can call your enemy? Though the chief mystery is how so deadly and unusual a poison could have gotten into a clean glass, without the knowledge of yourself or the nurse, still it might not be amiss to know if there is any one, here or elsewhere, who for any reason might desire your death."
The surprise in the child-like eyes increased rather than diminished.
"I don't know what to say," she murmured. "I am so insignificant and feeble a person that it seems absurd for me to talk of having an enemy. Besides, I have none. On the contrary, every one seems to love me more than I deserve. Haven't you noticed it, Mrs. Dayton?"
The landlady smiled and stroked the sick girl's hand.
"Indeed," she replied, "I have noticed that people love you, but I have never thought that it was more than you deserved. You are a dear little thing, Addie."
And though she knew and I knew that the "every one" mentioned by the poor girl meant ourselves, and possibly her unknown employer, we were none the less touched by her words. The more we studied the mystery, the deeper and less explainable did it become.
And indeed I doubt if we should have ever got to the bottom of it, if there had not presently occurred in my patient a repetition of the same dangerous symptoms, followed by the same discovery, of poison in the glass, and the same failure on the part of herself and nurse to account for it. I was aroused from my bed at midnight to attend her, and as I entered her room and met her beseeching eyes looking upon me from the very shadow of death, I made a vow that I would never cease my efforts till I had penetrated the secret of what certainly looked like a persistent attempt upon this poor girl's life.
I went about the matter deliberately. As soon as I could leave her side, I drew the nurse into a corner and again questioned her. The answers were the same as before. Addie had shown distress as soon as she had swallowed her usual quantity of medicine, and in a few minutes more was in a perilous condition.
