empty.” “If he had to put up with your relatives as a steady diet, I can’t say that I blame him,” Kennon said. “Careful, Doctor. You’re talking about my kinfolk,” Alexander said wryly. “At that, though, you have a point.” The two men slipped quietly from the room. Apparently none of the Family was conscious of their departure except Eloise, who watched them leave with an enigmatic expression on her narrow face. They left the fortress through the rear gate and walked slowly down the winding path that led to the cluster of buildings in the valley below. It was a beautiful night, calm and clear with the stars shining down from the dark vault of the heavens. The constellations were strange, and Kennon missed the moons.
