There had been only a glimpse as the wrench slipped from Victor Schenley's hand and fell between the sprocket and drive chain of the big new compressor in the Institute's basement. He wondered. That look on Schenley's darkly saturnine face could have been merely imagination. Or horror. But there was something about the man.... Still Eldon discounted his suspicions as the unworthy inventions of a disturbed mind.

Only the quick reflexes that had once made him a better than average halfback had saved him from instant death as the jagged end of the heavy sprocket chain lashed out with the speed of an enraged cobra. And often during the pain-wracked weeks that followed he had almost wished he had been a little slower.

The ring sparkled tauntingly under his desk lamp. Margaret had returned it by mail, and though the wording of her note had been restrained its tone had been final.

He picked up the pen again and moved the stub of his left arm, amputated just above the elbow, to hold the paper in place. But he had forgotten again how light and unmanageable the stump was. The paper skidded and the pen left a long black streak and a blot.

Eldon made a choked sound that was partly a shout of anger and partly a whimper of frustration. He crumpled the note, hurled the pen clumsily toward the far wall, and buried his disfigured face in the curve of his single arm. His body shook with sobs of self-pity.

There was only an inch or so left in the bottle. He finished it in a single gulp and for a moment stood hesitantly. Then he switched on the brilliant overhead lights. Liquor could not banish his tormenting thoughts, but perhaps work might. His letter to Margaret would have to wait.

His equipment was just as he had left it that night so many months ago when Victor Schenley had called him to see the new compressor. The setup was almost complete for another experiment with the resonance of bound charges. Bound charges were queer things, he reflected, a neglected field of investigation. They were classed as electrical phenomena more for convenience than accuracy. Eldon's completed experiments indicated they might be—something else. They disobeyed too many of the generally accepted electrical and physical laws. Occasionally individual charges behaved as though they were actually alive and responding to external stimuli, but the stimuli were non-existent or at least undetectable. And two or more bound charges placed in even imperfect resonance produced strange and inexplicable effects.

Working clumsily, he made the few remaining connections and set the special charge concentrators whining. The vacuum pumps clucked. A strain developed in the space around which the triplet charges were forming, something he could sense without seeing or hearing it. Now if only he could match the three charges for perfect resonance....


The lacquer on Margaret Mason's fingernails was finally dry. She slipped out of her robe and, without disturbing her carefully arranged pale gold hair, dropped the white evening gown over her shoulders and gently tugged it into place around slender hips. This should be the evening when Victor stopped his sly suggestions and made an outright proposal of marriage. Mrs. Victor Schenley. Margaret savored the name. She knew what she wanted.
