The Curious Cases of Detective Richard Duvall (All 3 Books in One Volume). Frederic Arnold Kummer
which seemed to lie on every side of him. In this effort he was equally unsuccessful. His head, his neck, his whole body, were rigid, immovable. He could not stir an inch in any direction.
He spent a long time in useless speculation upon the meaning of the remarkable situation in which he now found himself. He felt no pain, no discomfort, except that which the brilliance of the light above him caused. He determined at length once more to open his eyes, in order to discover if possible its source.
Even when his eyes were closed, he could see that the strange light burnt upon them. In a way it rendered his eyelids translucent—he was conscious of a dull pulsing redness through which shot a network of lines of fire. He opened his eyes slowly, cautiously, and looked upward. From some point above him, in what he judged must be the ceiling of the room, extended a beam of violet white light, cutting sharply through the darkness like the rays of a searchlight. At the opening in the ceiling through which it came, this beam was in diameter not more than two inches, but as it extended downward, it widened, taking the form of a long, thin, truncated cone, so that its width, where it impinged upon his face, was perhaps equal to twice that of a man's hand.
The darkness of the room about him made the beam of light seem a tangible, material thing. Its brilliance was unwavering—it extended from the ceiling to the surface of his face with the solidity, almost, of some huge, glittering icicle. He felt as though, were his hands but free, he could brush it aside, fling it off bodily into the darkness.
The effort of looking directly at the source of the light made his eyes smart with pain, but he found that by half-closing them, he could look off into the darkness, through the brilliant cone. In the pathway of its rays danced and tumbled innumerable dust specks—he knew then but for their presence, to afford the light a reflecting surface, its rays would be invisible to him.
In color the light was not yellow, like sunlight, but had a cold violet-blue quality, more nearly resembling moonlight. Its intensity, as well as the shape of the light cone, made him conclude that it was being focused through a powerful lens, or projected by means of a brilliant reflector.
He could imagine no possible reason for the situation in which he found himself. What the purpose of the beam of light was; why it thus focused upon his upturned face, he could not guess. He thought about it for many minutes, his eyes closed, his head straining restlessly toward the soft outer darkness. Presently there flashed into his mind Dr. Hartmann's words at their last meeting: "While I know how to cure mental disorders, I also know how to create them." The thought made him shudder. Was this, then, the explanation of his predicament? Somewhere he had read, not long before, a newspaper account of the investigations of certain Italian scientists, concerning the effect of the violet and ultra-violet light rays upon the cells of the brain. He could not recollect just what the conclusions had been, but he did remember that the newspaper article spoke of the popular superstition that moonlight could cause insanity. He knew Hartmann to be a scientist of vast ability and resource, and realized that back of the elaborate preparations he had evidently made must lie some sinister purpose.
For what seemed an eternity he lay thinking, unable to come to any rational conclusion. The distressing effect of the light rays increased, rather than diminished, as his nerves became more and more unstrung. It seemed, even with, his eyes closed, that he could feel the weight of the cone of light upon his face. The desire to escape from its searching glare became well-nigh irresistible. How long would this torture continue? He began to feel intensely tired and worn out and realized that could he but shut out the blinding brilliancy which enveloped him, he would sink exhausted to sleep. Sleep! He could no more sleep, under the present conditions, than he could fly to the moon. Then there came to his mind a recollection of a form of torture practised among the Chinese, the prevention of sleep. Prisoners, he had read, were confined in a cage, in brilliant sunlight, and prevented from sleeping by being prodded from without with spears. At the expiration of a week, he had read, the victim goes raving mad. Was this, then, Hartmann's intention?
Whatever the man did, he knew he would adopt only such methods as would involve him in no damaging consequences. He might be kept in his present situation until insanity ensued, and Hartmann with his reputation as a physician, a scientist, could calmly deny any story he might tell, putting it down to the wanderings of a disordered brain. He realized the cunning of the man, his care to use no physical violence. Should he, Duvall, under the strain of the torture which he realized lay before him, consent to disclose the whereabouts of the ivory snuff box, in return for his liberty, what could he do, in retaliation? Hartmann would calmly deny his story, and would doubtless produce witnesses, such as Mayer, to prove that the detective came to him for treatment for some slight mental disorder, some lapse of memory and that the exposure to the light rays had been but part of his usual treatment. Clearly the doctor had covered his tracks most successfully.
Throughout all these torturing thoughts, the figure of Grace came and went unceasingly. What would she do—what could she do, to aid him? He had warned her not to ask Mr. Phelps to take any steps looking to his release. He realized that were Hartmann to appear now, and give him his freedom, he would not dare to accept it. That the doctor might do this very thing was his greatest fear. If he should insist upon his leaving the place, what could he do, then, to recover Monsieur de Grissac's snuff box? He prayed fervently that Dufrenne and his companions might in some way work out a plan to set matters right.
Presently he fell to thinking of the snuff box, and its safety. How fortunate it seemed, that the doctor and his man Mayer had overlooked the opera hat. He wondered if they had thought of it since? It was clear that they had not, else he would no longer be kept a prisoner. What was the room beneath the laboratory used for? Its appearance had suggested that it was not used at all—a mere lumber-room, a place for storing boxes and crates. And then there flashed into his mind the thought, where was he now? From the apparent distance of the ceiling, as shown by the beam of light, he concluded that he was lying on the floor, a conclusion which the hardness and coldness of the surface beneath him amply proved. Evidently it was a floor of stone, or cement, not one of wood. A certain sense of familiarity in his surroundings came over him. The faint radiance which was diffused about him by the light cone showed the walls before and on either side of him to be of uniform blackness, unrelieved by any suggestion of windows. He strove with all his power to pierce the shadowy gloom, to come upon some point of recognition, but the darkness baffled him.
In one corner a huge shadow, bulking formless against the wall, suggested the packing case behind which his opera hat had been tossed by Mayer during the search the night before. The thought thrilled him with renewed hope. What more likely place, after all, for Hartmann's deviltries than this silent room beneath the laboratory? If he was lying there now, and chance of escape should come, he might even yet be able to take the missing snuff box with him.
The hours dragged interminably. He was conscious of a keen feeling of pain, a smarting irritation, in his eyes, which caused tiny streams of moisture to trickle beneath their lids and roll unheeded down his cheeks. The muscles of his neck became sore and swollen, from his incessant though useless effort to turn aside his head. A dull pain began to shoot insistently through his temples, and his limbs became numb and cold. The desire to escape from the relentless brilliance of the light cone became unbearable; he felt as though, if relief did not soon come, he would shriek out in a madness of terror. Then the hopelessness of doing so became apparent, and he nerved himself with all the power of his will to endure the ever-increasing torture. Yet this torture was, he knew, largely mental—the actual pain was by no means unbearable; it was only the dull, insistent pounding of the light rays upon his eyes, his brain, from which he longed to escape. With closed eyes and tensely drawn nerves, he waited, watching the endless play of the tracery of light in the dull redness of his eyelids.
The sudden sharp rattle of a key in the door, followed by the turning of the knob, told him that someone was entering the room. He had a momentary vision of a patch of light, yellow against the surrounding blackness, which disappeared almost instantly as the door was closed. Then he was conscious of a shadowy form beside him, and heard the smooth, modulated tones of Dr. Hartmann's voice.
"Well, Mr. Duvall," he said, "how goes the treatment? Memory any better this morning?"
He made no reply. The mockery in the doctor's voice roused him
