Smith lurched back as though he had received a physical blow, and clutched my shoulder convulsively. Beneath the heavy tan his face had blanched, and his eyes were set in a stare of horror.
"My God!" he whispered. "I am too late!"
With clenched fists he turned and, pressing through the group of loungers, bounded up the steps. In the hall a man who unmistakably was a Scotland Yard official stood talking to a footman. Other members of the household were moving about, more or less aimlessly, and the chilly hand of King Fear had touched one and all, for, as they came and went, they glanced ever over their shoulders, as if each shadow cloaked a menace, and listened, as it seemed, for some sound which they dreaded to hear. Smith strode up to the detective and showed him a card, upon glancing at which the Scotland Yard man said something in a low voice, and, nodding, touched his hat to Smith in a respectful manner.
A few brief questions and answers, and, in gloomy silence, we followed the detective up the heavily carpeted stair, along a corridor lined with pictures and busts, and into a large library. A group of people were in this room, and one, in whom I recognized Chalmers Cleeve, of Harley Street, was bending over a motionless form stretched upon a couch. Another door communicated with a small study, and through the opening I could see a man on all fours examining the carpet. The uncomfortable sense of hush, the group about the physician, the bizarre figure crawling, beetle-like, across the inner room, and the grim hub, around which all this ominous activity turned, made up a scene that etched itself indelibly on my mind.
As we entered Dr. Cleeve straightened himself, frowning thoughtfully.
"Frankly, I do not care to venture any opinion at present regarding the immediate cause of death," he said. "Sir Crichton was addicted to cocaine, but there are indications which are not in accordance with cocaine-poisoning. I fear that only a post-mortem can establish the facts—if," he added, "we ever arrive at them. A most mysterious case!"
Smith stepping forward and engaging the famous pathologist in conversation, I seized the opportunity to examine Sir Crichton's body.
The dead man was in evening dress, but wore an old smoking-jacket. He had been of spare but hardy build, with thin, aquiline features, which now were oddly puffy, as were his clenched hands. I pushed back his sleeve, and saw the marks of the hypodermic syringe upon his left arm. Quite mechanically I turned my attention to the right arm. It was unscarred, but on the back of the hand was a faint red mark, not unlike the imprint of painted lips. I examined it closely, and even tried to rub it off, but it evidently was caused by some morbid process of local inflammation, if it were not a birthmark.
Turning to a pale young man whom I had understood to be Sir Crichton's private secretary, I drew his attention to this mark, and inquired if it were constitutional. "It is not, sir," answered Dr. Cleeve, overhearing my question. "I have already made that inquiry. Does it suggest anything to your mind? I must confess that it affords me no assistance."
"Nothing," I replied. "It is most curious."
