Partially removing the dust from my smarting eyes, I returned to the embrasure, and stepping from the chair on to the deep ledge, I grasped the corner of the quaint, diamond-paned window, which I had opened to its fullest extent, and craned forth.
Now I could see the ivy-grown battlements surmounting the tower (the east wing, in which my room was situated, was the oldest part of Graywater Park). Sharply outlined against the cloudless sky they showed … and the black silhouette of a man's head and shoulders leant over directly above me!
I drew back sharply. The climber, I thought, had not seen me, although he was evidently peering down at my window. What did it mean?
As I crouched in the embrasure, a sudden giddiness assailed me, which at first I ascribed to a sympathetic nervous action due to having seen the man poised there at that dizzy height. But it increased, I swayed forward, and clutched at the wall to save myself. A deadly nausea overcame me … and a deadly doubt leapt to my mind.
In the past, Sir Lionel Barton had had spies in his household; what if the dark-faced Greek, Homopoulo, were another of these? I thought of the '45 port, of the ghostly rapping; and I thought of the man who crouched upon the roof of the tower above my open window.
My symptoms now were unmistakable; my head throbbed and my vision grew imperfect; there had to be an opiate in the wine!
I almost fell back into the room. Supporting myself by means of the chair, the chest of drawers, and finally, the bed-rail, I got to my grip, and with weakening fingers, extracted the little medicine-chest which was invariably my traveling companion.

Grimly pitting my will against the drug, but still trembling weakly from the result of the treatment, internal and subcutaneous, which I had adopted, I staggered to the door out into the corridor and up the narrow, winding stairs to Smith's room. I carried an electric pocket-lamp, and by its light I found my way to the triangular, paneled landing.
I tried the handle. As I had expected, the door was locked. I beat upon it with my fist.
