But she was acting for David, and she was here to find out what this Frank was planning. She must make some guesses, and then see if she could get him to confirm them. Such as, where was he going, and why was he leaving the Tartars behind?

She had to tilt her head back to look into his troubled face. "Come, let us sit down," she said.
