Usually, some time during the night, he awoke, slid cautiously and with infinite stealth from beneath the covers and closed the wide-flung window to within a bare two inches of the sill.

As she lay there, smiling a little grimly in the dark and giving no sign of being awake, she thought, “Oh, well, I guess a closed window won’t kill me either.”

Still, sometimes, just to punish him a little, and to prove that she was nobody’s fool, she would wait until he had dropped off to sleep again and then she, too, would achieve a stealthy trip to the window and would raise it slowly, carefully, inch by inch.
