" Humphrey dimmed his flashlight and stayed where he was, quiet and still in the shadows of the bathing house. In the nearby clearing on the bank of the lake, glass lanterns had been strung from the branches and candles flickered in the warm night air. A girl on the threshold of adulthood was standing amongst them, feet bare and only the simplest of summer dresses grazing her knees. Her dark hair fell loose in waves over her shoulders and moonlight dripped over the scene to cast a luster along her profile. Humphrey could see that her lips were moving, as if she spoke the lines of a poem beneath her breath.
Her face was exquisite, yet it was her hands that entranced him. While the rest of her body was perfectly still, her fingers were moving together in front of her chest, the small but graceful motions of a person weaving together invisible threads.
He had known women before, beautiful women who flattered and seduced, but this girl was different. There was beauty in her focus, a purity of purpose that reminded him of a child's, though she was most certainly a woman. To find her in these natural surrounds, to observe the free flow of her body, the wild romance of her face, enchanted him.
Humphrey stepped out of the shadows. The girl saw him but she didn't start. She smiled as if she'd been expecting him, and gestured towards the rippling lake. "There's something magical about swimming in the moonlight, don't you think? "
