There were other points, too. I recalled the word that sounded like "Pol'n," which Mr. Graves had used in speaking to the housekeeper. Apparently it was a Christian name of some kind; but why did Mr. Graves call the woman by her Christian name when Mr. Weiss addressed her formally as Mrs. Schallibaum? And, as to the woman herself: what was the meaning of that curious disappearing squint? Physically it presented no mystery. The woman had an ordinary divergent squint, and, like many people, who suffer from this displacement, could, by a strong muscular effort, bring the eyes temporarily into their normal parallel position. I had detected the displacement when she had tried to maintain the effort too long, and the muscular control had given way. But why had she done it? Was it only feminine vanity—mere sensitiveness respecting a slight personal disfigurement? It might be so; or there might be some further motive. It was impossible to say.
Turning this question over, I suddenly remembered the peculiarity of Mr. Weiss's spectacles. And here I met with a real poser. I had certainly seen through those spectacles as clearly as if they had been plain window-glass; and they had certainly given an inverted reflection of the candle-flame like that thrown from the surface of a concave lens. Now they obviously could not be both flat and concave; but yet they had the properties peculiar to both flatness and concavity. And there was a further difficulty. If I could see objects unaltered through them, so could Mr. Weiss. But the function of spectacles is to alter the appearances of objects, by magnification, reduction or compensating distortion. If they leave the appearances unchanged they are useless. I could make nothing of it. After puzzling over it for quite a long time, I had to give it up; which I did the less unwillingly inasmuch as the construction of Mr. Weiss's spectacles had no apparent bearing on the case.
On arriving home, I looked anxiously at the message-book, and was relieved to find that there were no further visits to be made. Having made up a mixture for Mr. Graves and handed it to the coachman, I raked the ashes of the surgery fire together and sat down to smoke a final pipe while I reflected once more on the singular and suspicious case in which I had become involved. But fatigue soon put an end to my meditations; and having come to the conclusion that the circumstances demanded a further consultation with Thorndyke, I turned down the gas to a microscopic blue spark and betook myself to bed.
Chapter IV
The Official View
I rose on the following morning still possessed by the determination to make some oportunity during the day to call on Thorndyke and take his advice on the now urgent question as to what I was to do. I use the word "urgent" advisedly; for the incidents of the preceding evening had left me with the firm conviction that poison was being administered for some purpose to my mysterious patient, and that no time must be lost if his life was to be saved. Last night he had escaped only by the narrowest margin—assuming him to be still alive—and it was only my unexpectedly firm attitude that had compelled Mr. Weiss to agree to restorative measures.
That I should be sent for again I had not the slightest expectation. If what I so strongly suspected was true, Weiss would call in some other doctor, in the hope of better luck, and it was imperative that he should be stopped before it was too late. This was my view, but I meant to have Thorndyke's opinion, and act under his direction, but
"The best laid plans of mice and men
Gang aft agley."
When I came downstairs and took a preliminary glance at the rough memorandum-book, kept by the bottle-boy, or, in his absence, by the housemaid, I stood aghast. The morning's entries looked already like a sample page of the Post Office directory. The new calls alone were more than equal to an ordinary day's work, and the routine visits remained to be added. Gloomily wondering whether the Black Death had made a sudden reappearance in England, I hurried to the dining-room and made a hasty breakfast, interrupted at intervals by the apparition of the bottle-boy to announce new messages.
