She looked and looked at the round, dull knob, like a mystic held by a hypnotist's crystal ball, and she began to breathe a little faster; she could feel her resolution tighten within her like a turning screw. Beneath her brows, heavy and thick for a woman's, her eyes flitted back to the man. With the careful affectation of doing nothing at all, a theatricalism that she detected instantly, but for which she could guess no reason, he was cutting away at the damp, close-gnawed seed of the peach, trying apparently to fashion some little trinket--a toy basket, possibly--from it. His fingers moved deftly over its slick, wet surface. He had already poured out some of the champagne. One of the pint bottles stood empty, with the distorted button-headed cork lying beside it, and in two glasses the yellow wine was fast going flat and dead in that stifling heat. It still spat up a few little bubbles to the surface, as though minute creatures were drowning in it down below. The man was sweating more than ever, so that, under the single, low-turned gas jet, his crooked face had a greasy shine to it. A church clock down in the next block struck twelve slowly. The sleepless flies buzzed evilly. "Look out again, won't you?" he said for perhaps the tenth time in two hours. "There's a chance, you know, that he might be gone--just a bare chance. And be sure you close the door into the hall behind you," he added as if by an afterthought. "You left it ajar once--this light might show through the window draperies." At his bidding she rose more willingly than at any time before. To reach the door she passed within a foot of the end of the couch, and watching over her shoulder at his hunched-up back she paused there for the smallest fraction of time. The damaged picture hat slid off on the floor with a soft little thud, but he never turned around. The instant, though, that the hall door closed behind her the man's hands became briskly active. He fumbled in an inner pocket of his unbuttoned waistcoat; then his right hand, holding a small cylindrical vial of a colorless liquid, passed swiftly over one of the two glasses of slaking champagne and hovered there a second. A few tiny globules fell dimpling into the top of the yellow wine, then vanished; a heavy reek, like the smell of crushed peach kernels, spread through the whole room. In the same motion almost he recorked the little bottle, stowed it out of sight, and with a quick, wrenching thrust that bent the small blade of his penknife in its socket he split the peach seed in two lengthwise and with his thumb-nail bruised the small brown kernel lying snugly within. He dropped the knife and the halved seed and began sipping at the undoctored glass of champagne, not forgetting even then to wave his fingers above it to keep the winged green tormentors out. The door at the front reopened and the woman came in. Her thoughts were not upon smells, but instinctively she sniffed at the thick scent on the poisoned air.
