feet through our shoes no matter how thick the soles."
Involuntarily she stopped and looked down. That explained the thickness of his rug. That explained why his movements were full of grace . . . he had always walked on soft, green grass.
She found herself turning to look at him. For the last time, she told herself. I'm going now but I want to see him once more . . .
"Are you leaving, Sara?" he seemed amused, and yet there was no mockery in his voice. Just as there was no smugness in his lie to Mr. Archer a few moments ago.
