“Often,” he said, “a substance which is poison to one person is harmless to another. If we could only discover what it really was which affected you, we might treat you for it and cure you much more rapidly. As matters rest, however, you must grow strong again by degrees, and thank Providence that you’re still alive. I confess when I first saw you, I thought you’d only a few minutes to live.”

“Was I so very bad?”

“As ill as you could be. You were cold and rigid, and looked as though you were already dead. In fact, any one but a doctor would, I believe, have pronounced life extinct. Your breath on a mirror alone showed respiration, although the heart’s movement was so weak as to be practically imperceptible. But don’t trouble further over it, you’ll be about soon,” and shortly afterwards he shook my hand and went on his way to the hospital, already late on my account.

I longed to tell him all the curious events of the past, but saw that such a course would be unwise. If I did so, Eva—the woman I adored—must be prematurely judged, first because of old Lowry’s revelations, and now secondly because of the suspicious fact of my illness after partaking of the wine she offered.

The idea that the attempt had been made upon me at Riverdene seemed very improbable, because I had dined in common with the other guests; the tea I had taken was poured from the same Queen Anne pot from which the cups of others were filled, and in the whisky-and-soda I had had before leaving I was joined by three other men who had rowed up from a house-boat about a quarter of a mile lower down.

As I lay there restless in my bed, trying vainly to read, I spent hours in recalling every event of that day, but could discover no suspicious circumstance other than that incident of the wine at The Hollies. I recollected how Eva after ringing for the servant and ordering it, had herself gone out into the dining-room, and had been absent a couple of minutes or so. Possibly she might only have gone there in order to unlock the cellarette, yet there were likewise, of course, other graver possibilities.

This thought which fastened upon my mind so tenaciously allowed me but little rest. I tried to rid myself of it, tried to scorn such an idea, tried to reason with myself how plain it was that she actually held me in some esteem, and if so she would certainly not seek to take my life in that cowardly, dastardly manner. Sometimes I felt that I misjudged her; at others grave suspicions haunted me. Yet withal my love for her never once wavered. She was my idol. Through those long, weary hours of prostration and convalescence I thought always of her—always.

I had written her a short note, saying that I was unwell and unable to go down to Riverdene, not, however, mentioning the cause of my illness, and in response there came in return a charmingly-worded little letter, expressing profound regret and hoping we should meet again very soon. A hundred times I read that note.

Was the thin, delicate hand that penned it the same that had endeavoured to take my life?

That was the sole question uppermost in my mind; a problem which racked my brain day by day, nay, hour by hour. But there was no solution. Thus was I compelled to exist in torturing suspicion, anxiety and uncertainty.
