How long a time elapsed between the moment when I saw light turned up in the laboratory and the interruption, I found great difficulty in determining afterwards. But the interruption was uncanny.
Mme Dubonnet, working in the kitchen, French fashion, with windows hermetically sealed, noticed nothing.
Already, on this momentous day, I had heard a sound baffling description; and it was written—for the day was one never to be forgotten—that I should hear another.
As I paused to light a fresh cigarette, from somewhere out-, side—I thought from the Comiche road above—came a cry, very low, but penetrating....
It possessed a quality of fear which chilled me like a sudden menace. It was a sort of mournful wail on three minor notes. But a shot at close quarters could not have been more electrical in its effect.
I dropped my cigarette and jumped up.
What was it?
It was unlike anything I had ever heard. But there was danger in it, creeping peril. I leaned upon the table, staring from the window upward, in the direction from which the cry seemed to have come.
And as I did so, I saw something.
I have explained that a beam of light from the laboratory window cut across the shadow below. On the edge of this light something moved for a moment—for no more than a moment—but instantly drew my glance downward.
I looked....
A pair of sunken, squinting eyes, set in a yellow face so evilly hideous that I was tempted then, and for sometime later, to doubt the evidence of my senses, watched me!
Of the body belonging to this head I could see nothing; it was enveloped in shadow. I saw just that evil mask watching me; then—it was gone!
As I stood staring from the window, stupid with a kind of horrified amazement, I heard footsteps racing down the path from the road which led to the door of Villa Jasmin. Turning, I ran out onto the verandah. I reached it at the same moment as the new arrival—a tall, lean man with iron-grey, crisply virile hair, and keen, eager eyes. He had the sort of skin which tells of years spent in the tropics. He wore no hat, but a heavy topcoat was thrown across his shoulders, clockwise. Above all, he radiated a kind of vital energy which was intensely stimulating.
“Quick,” he said—his mode of address reminded me of a machine gun—”where is Dr. Petrie? My name is Nayland Smith.”
“I’m glad you have come. Sir Denis,” I replied; and indeed I spoke sincerely. “The doctor referred to you only to-day. My name is Alan Sterling.”
“I know it is,” he said, and shook hands briskly; then:
“Where is Petrie?” he repeated. “Is he with you?” “He is in the laboratory, Sir Denis. I’ll show you the way.” Sir Denis nodded, and we stepped off the verandah. “Did you hear that awful cry?” I added. He stopped. We had just begun to descend the slope. “You heard it?” he rapped in his staccato fashion. “I did. I have never heard anything like it in my life!” “I have! Let’s hurry.”
There was something very strange in his manner, something which I ascribed to that wailing sound which had electrified me. Definitely, Sir Denis Nayland Smith was not a man susceptible to panic, but some fearful urgency drove him to-night.
I was about to speak of that malignant yellow face when, as we came in sight of the lighted windows of the laboratory:
“How long has Petrie been in there?” Nayland Smith asked. “All the afternoon. He’s up to his eyes in work on these mysterious cases—about which, perhaps, you know?” “I do,” he replied. “Wait a moment....” He grasped my arm and pulled me up just at the edge of the patch of shadow. He stood still, and I could tell that he was listening intently.
“Where’s the door?” he asked suddenly.
“At the farther end.”
“Right.”
He set off at a run, and I followed past the lighted window. Petrie was not at the table nor at the bench. I was puzzled to account for this, and already vaguely fearful. A premonition gripped me, a premonition of something horrible. Then, I had my hand on the door and had thrown it open. I entered. Sir Denis close behind me.
“Good God! Petrie!...Petrie, old man...”
Nayland Smith had sprung in and was already on his knees beside the doctor.
Petrie lay in the shadow of his working bench, in fact, half under it, one outstretched hand still convulsively gripping its edge!
I saw that the apparently rigid fingers grasped a hypodermic syringe. Near to his upraised hand was a vessel containing a small quantity of some milky fluid; and the tube of white powder which he had shown to me lay splintered, broken by his fall, on the floor a foot away.
In those few fleeting seconds I saw Sir Denis Nayland Smith, for the first and last time in my knowledge of him, fighting to subdue his emotions. His head dropped into his upraised hands, his fingers clutched his hair.
Then he had conquered. He stood up.
“Lift him!” he said hoarsely—”out here, into the light.”
I was half stunned. Horror and sorrow had me by the throat. But I helped to move Petrie farther into the middle of the floor, where a central light shone down upon him. One glance told me the truth—if I had ever doubted it.
A sort of cloud was creeping from his disordered hair, down over his brow.
“Heaven help him!” I whispered. “Look—look!...the purple shadow!”
chapter fifth
THE BLACK STIGMATA
the laboratory was very silent. Through the windows, which still remained open, I could hear the hum of the Kohler engine in its little shed at the bottom of the garden—the chirping of crickets, the clucking of hens.
There was a couch littered with books and chemical paraphernalia. Sir Denis and I cleared it and laid Petrie there.
I had telephoned Dr. Cartier from the villa.
That ghastly purple shadow was creeping farther down my poor friend’s brow.
“Shut the door. Sterling,” said Nayland Smith sharply.
I did so.
“Stand by,” he went on, and pointed.
Petrie, who wore a woollen pullover with long sleeves when he was working late, had evidently made an attempt to peel it off just before coma had claimed him.
“You see what he meant to do,” Nayland Smith went on. “God knows what the consequences will be, but it’s his only chance. He must have been fighting it off all day. The swelling in his armpit warned him that the crisis had come.”
He examined the milky liquid in a small glass measure.
“Have you any idea what this is?”
I indicated the broken tube and scattered white powder on the floor.
“A preparation of his own—to which I have heard him refer as ‘654.’ He believed it was a remedy, but he was afraid to risk it on a patient.”
“I wonder?” Sir Denis murmured. “I wonder——”
Stooping, I picked up a fragment of glass to which one of Petrie’s neatly written labels still adhered.
“Look here, Sir Denis!”
He read aloud:
“‘654.’ 1 grm. in 10 c.c. distilled water: intravenous.”
He stared at me hard, then:
“It’s kill or cure,” he rapped. “We have no choice....”
“Shouldn’t we wait for Dr. Cartier?”
“Wait!” His angry glare startled me. “With luck, hell be here in three quarters of an hour. And life or death in this thing is a matter of minutes’. No! Petrie must have his chance. I’m not an expert—but I can do my best....”
I experienced some difficulty in assisting at what followed;
but Nayland Smith, his course set, made the injection as coolly as though he had been used to such work for half a lifetime. When it was done:
“If Petrie survives,” he said quietly, “his own skill will have saved him—not ours. Lay that rug over him. It strikes one as chilly in here.”
