During that week—for it was only a week before the crisis came—I was in the habit of going down each evening, after the work of the day was done, to inquire about my new arrangements. One night, it was a cold and windy evening in March, I had just stepped out from the hall door when a strange sight met my eyes. A man was crouching before one of the windows of the house. His knees were bent and his eyes were fixed upon the small line of light between the curtain and the sash. The window threw a square of brightness in front of it, and in the middle of this the dark shadow of this ominous visitor showed clear and hard. It was but for an instant that I saw him, for he glanced up and was off in a moment through the shrubbery. I could hear the patter of his feet as he ran down the road, until it died away in the distance.
It was evidently my duty to turn back and to tell Dr. McCarthy what I had seen. I found him in his study. I had expected him to be disturbed at such an incident, but I was not prepared for the state of panic into which he fell. He leaned back in his chair, white and gasping, like one who has received a mortal blow.
“Which window, Mr. Weld?” he asked, wiping his forehead. “Which window was it?”
“The next to the dining-room—Mr. St. James’s window.”
“Dear me! Dear me! This is, indeed, unfortunate! A man looking through Mr. St. James’s window!” He wrung his hands like a man who is at his wits’ end what to do.
“I shall be passing the police-station, sir. Would you wish me to mention the matter?”
“No, no,” he cried, suddenly, mastering his extreme agitation; “I have no doubt that it was some poor tramp who intended to beg. I attach no importance to the incident—none at all. Don’t let me detain you, Mr. Weld, if you wish to go out.”
I left him sitting in his study with reassuring words upon his lips, but with horror upon his face. My heart was heavy for my little employer as I started off once more for town. As I looked back from the gate at the square of light which marked the window of my colleague, I suddenly saw the black outline of Dr. McCarthy’s figure passing against the lamp. He had hastened from his study then to tell St. James what he had heard. What was the meaning of it all, this atmosphere of mystery, this inexplicable terror, these confidences between two such dissimilar men? I thought and thought as I walked, but do what I would I could not hit upon any adequate conclusion. I little knew how near I was to the solution of the problem.
It was very late—nearly twelve o’clock—when I returned, and the lights were all out save one in the Doctor’s study. The black, gloomy house loomed before me as I walked up the drive, its sombre bulk broken only by the one glimmering point of brightness. I let myself in with my latch-key, and was about to enter my own room when my attention was arrested by a short, sharp cry like that of a man in pain. I stood and listened, my hand upon the handle of my door.
All was silent in the house save for a distant murmur of voices which came, I knew, from the Doctor’s room. I stole quietly down the corridor in that direction. The sound resolved itself now into two voices, the rough bullying tones of St. James and the lower tone of the Doctor, the one apparently insisting and the other arguing and pleading. Four thin lines of light in the blackness showed me the door of the Doctor’s room, and step by step I drew nearer to it in the darkness. St. James’s voice within rose louder and louder, and his words now came plainly to my ear.
