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. Eldon had seemed a good idea at the time, the best she could do. Despite his youth he was already Associate Director of the Institute, seemed headed for bigger things, and a couple of patents brought him modest but steady royalties. And, best of all, his ridiculously straightforward mind made him easy to handle. It had seemed a good idea until the afternoon Victor Schenley had sauntered into her office in the administrative wing of the Institute and she had seen that look come into his eyes. She had recognized him instantly from the pictures the newspapers had carried when he inherited the great Schenley fortune, and had handled that first meeting with subtle care.
