Miss Green was back with a soft hum of wings, on the outer window sill, six feet from where he sat. She pushed the knotted scrap of cloth through the screen. There was something inside it now; it caught for a moment on the wires. Mel started up to help, then checked himself, afraid of feeling some bug squirming desperately inside; and while he hesitated, she had shoved it through. She followed it, picked it up again and flew off to the living room. After a moment she returned with the empty cloth and went out again. She made eight such trips in the next hour, while night deepened outside and then began to lighten as a half-moon shoved over the horizon. Mel must have dozed off several times; at least, he suddenly found himself coming awake, with the awareness that something had just landed with a soft thump on the window sill outside. It wasn't Miss Green. He saw a chunky shadow at one corner of the window, and caught the faintest glint of green eyes peering into the room. It was the cat from the courtyard. In the same moment, he heard the familiar faint hum, and Miss Green appeared at the opposite end of the sill. * * * * * Afterward, Mel realized he'd simply sat there, stiffening in groggy, sleep-dazed horror, as the cat-shadow lengthened and flowed swiftly toward the tiny humanoid figure. Miss Green seemed to raise both arms over her head. A spark of brilliant blue glowed from her cupped hands and extended itself in an almost invisible thread of fire that stabbed against the cat's forehead. The cat yowled, swung aside and leaped down into the court. Mel was on his feet, shaking violently, as Miss Green slipped in through the screen. He heard Maria open her window upstairs to peer down into the court, where the cat was making low, angry sounds. Apparently it hadn't been hurt, but no wonder Maria had suspected that afternoon she'd been stung by a wasp! Or that Miss Green's insect victims never struggled, once she had caught them! He pulled down the shade and stood undecided in the dark, until he heard her piping call from the living room. It was followed by an impatient buzzing about the standing lamp in there, and Mel concluded correctly that he was supposed to turn on the light. He discovered her on the living room table, sorting out the plunder she had brought back. It wasn't a pile of electrocuted insects, as he had expected, but a puzzlingly commonplace collection--little heaps of dry sand from the beach, some small white pebbles, and a sizable bundle of thin twigs about two inches in length. Since she was disregarding him, he shifted the lamp over to the table to see what this human-shaped lightning bug from another dimension was going to do next. That was the way he felt about Miss Green at the moment....
