Miss Green looked up at him and smiled. She was much more alert and vivacious than the other one who, perhaps because of her condition, merely sat or lay there gracefully and let Miss Green wait on her. The relationship seemed to be about that of an elf princess and her personal attendant, but they were much too real-seeming creatures to have popped out of a fairy tale, though their appearance did arouse recurrent bursts of a feeling of fairy tale unreality, which Mel hadn't known since he was ten. But, tiny as they were, Miss Green and the princess primarily gave him the impression of being quite as functional as human beings or, perhaps, as field mice. He would have liked to inspect the brittle-seeming wings more closely. They seemed to be made up of numerous laminated, very thin sections, and he wondered whether they could fly with them or whether their race had given up or lost that ability. But touching them might have affected their present matter-of-fact acceptance of him, and he didn't want to risk that.... A door banged suddenly in the apartment overhead. A moment later, he heard Maria coming down the hall stairs. Mel stood up in sudden alarm. He'd known for some time that his neighbor had supplied herself with a key to his apartment, not to pry but with the practical purpose of borrowing from the little bar in Mel's living room when she was out of both money and liquor. She rarely took much, and until now he'd been more amused than annoyed. * * * * * He went hurriedly into the living room, closing the door to the kitchenette behind him. If Maria knocked, he wouldn't answer. If she decided he was out and came in to steal his liquor, he would pretend to have been asleep in the chair and scare the hell out of her! She paused before the apartment door a moment, but then went out into the court. Mel waited until her footsteps died away, going toward the street. As he opened the door to the kitchenette, something buzzed noisily out of the living room past his shoulder--a big, unlovely looking horsefly. The apartment screens didn't fit too well, and the fly probably had been attracted by the smell of food. Startled, he stopped to consider the new problem. There was a flyswatter hanging beside the door, but he didn't want to alarm his guests--and then, for the first time, he saw Miss Green's wings unfold! She was up on her feet beside the princess, who remained sitting on the towel. Both of them were following the swift, erratic course of the big fly with more animation than they'd shown about anything so far. Miss Green gave a sudden piping cry, and the glassy appendages on her back opened out suddenly like twin transparently gleaming fans, and blurred into motion too swift for Mel to follow. Miss Green rose into the air like a tiny human helicopter, hands up before her as if she were praying.
