Sure enough, when he looked over his shoulder, he was aware of a donkey and his rider drawing smoothly and silently near. The pair of them were so nearly of the colour of the ground, he had to look long to be sure; and as he looked, Manuela suddenly leaned sideways and saw what he saw. It was just as if she had received a stroke of the sun. She stiffened; he felt the thrill go through her; and when she resumed her first position she was another person.

CHAPTER V

THE AMBIGUOUS THIRD

"God save your grace," said Estéban; for it was he who, sitting well back upon his donkey's rump, with exceedingly bright eyes and a cheerful grin, now forged level with Manvers and his burdened steed.

Manvers gave him a curt "Good-day," and thought him an impudent fellow—which was not justified by anything Estéban had done. He had been discretion itself; and, indeed, to his eyes there had been nothing of necessity remarkable in the pair on the horse. If a lady—Duchess or baggage—happened to be sharing the gentleman's saddle, an arrangement must be presumed, which could not possibly concern himself. That is the reasonable standpoint of a people who mind their own business and credit their neighbours with the same preoccupation.

But Manvers was an Englishman, and could not for the life of him consider Estéban as anything but a puppy for seeing him in a compromising situation. So much was he annoyed that he did not remark any longer that Manuela was another person, sitting stiffly, strained against his arm, every muscle on the stretch, as taut as a ship's cable in the tideway, her face in rigid profile to the newcomer.

Estéban was in no way put out. "Many good days light upon your grace!" he cheerfully repeated—so cheerfully that Manvers was appeased.

"Good-day, good-day to you," he said. "You ride light and I ride heavy, otherwise you had not overtaken us."

Estéban showed his fine teeth, and waved his hand towards the hazy distance; from the tail of his eye he watched Manuela in profile. "Who knows that, sir? Lo que ha de ser—as we say. Ah, who knows that?" Manuela strained her face forward.
