Slowly the day passed. He concluded that it was afternoon, when he heard far off a bell striking the hour of two, although it might equally well have been two o'clock in the morning, for all he could tell. There was a faint hum of conversation in the laboratory above him, which convinced him that it was still day.
Presently his ear, acutely sensitive to the slightest noise which might disturb the stillness about him, became aware of a faint sound of music, which seemed to come to him from a long distance off. It was a popular French march, and from a certain quality of the notes he concluded that it was being played upon a phonograph. The strains of the music distracted him, took his mind from the things about him, and as he listened to it, it seemed that the effort of keeping his eyes tightly closed grew sensibly less, the blinding pressure of the unwavering light cone upon his face appreciably easier to bear. He knew that this was but a momentary relief, but he welcomed it eagerly. Lying in this terrifying silence, under the cruel glare of light, had become frightful—he wondered if, after all, his nerves, his mind, could long stand the strain.
The music stopped suddenly. He found himself eagerly hoping that there would be more. In a few moments it began again, and he was listening to the familiar strains of The Rosary. He had always liked the song—Grace, too, had been fond of it. He wondered if she could be playing to him, trying to soothe his fast-shattering nerves with music. It pleased him to think that it might be so, although he had no reason to suppose that Grace knew of the torture to which Dr. Hartmann was subjecting him.
After a time, the final strains of The Rosary died away, to be followed by a German march, played by some military band. This, too, he was glad to hear, although he found himself thinking that he preferred The Rosary. As if in answer to his thoughts, it began again—he found himself repeating the words to himself mechanically, and thinking of Grace.
The music continued for long over an hour. Duvall noted with surprise that while there were many other selections, The Rosary was played almost every other time. So often, in fact, did its strains break the stillness, that he became annoyed—in his nervous state this constant repetition of the song worried him. After a time he shuddered when he heard it, hoping that each time would be the last. No one but an imbecile, he muttered to himself, could enjoy playing a piece over and over in that aimless fashion. When at last the impromptu concert had ceased, and the silence about him was once more unbroken, he found himself puzzling in vain over the matter, as though it had become of vast importance to him.
After the music ceased, he realized how much it had helped him to endure the two or more hours which had elapsed since Hartmann left him. His real tortures were only just beginning. The constant blaze of light on his face, the ceaseless effort to keep his eyes closed, to turn his head away, in spite of the bonds which prevented it, once more almost frenzied him. He fell to wondering whether Hartmann had been in earnest, when he told him of the qualities of the violet rays. Could they in any way affect his mind? The mere thought stimulated his imagination to such an extent that already he was convinced that his senses were wandering—that his mind was becoming sluggish and dull.
As hour after hour passed, this thought became almost a certainty. His head began again to ache terribly, his eyes seemed to swim in pools of liquid fire. Bright flashes of light darted through his brain, and at times it seemed almost on fire. The pain which the constant effort to turn his head caused, was becoming more acute as each minute passed—he felt constantly on the point of screaming out in terror—begging for release—agreeing to do anything they asked of him. Then with a mighty effort of the will he would calm himself, and closing his eyes tightly once more, determine to endure until the end.
After an interminable period, the sound of the music once more fell upon his troubled brain. This time the strains sounded more distinct and clear. Three times in rapid succession The Rosary was played, then sudden silence. He waited in vain for more—dreading the recurrence of the song, yet expecting it, as one expects the continuance of any oft-repeated sound. There was nothing further, however, and once more the silence became like the darkness about him, a grim and positive thing.
Hours later, when his brain reeled endlessly in a blazing redness, and his tortured eyes seemed bursting from their sockets, the cone of violet light vanished as though some silent hand had brushed it aside, and in the reaction he fainted.
He awoke again to find himself lying on the floor, with Hartmann bending over him, feeling his pulse. In a fit of rage, he struck out with his clenched hand, and missing, scrambled to his feet. The room was faintly lit by the single electric globe, and he saw Mayer and Dr. Hartmann confronting him, the latter with a revolver in his hand. Once more he realized the futility of resistance, and sank against a packing box, his hand covering his burning eyes.
