After dinner Annesley tried to read a new book from the library at El Paso, but between her eyes and the printed page would float the picture of a small, open automobile and its driver lost in clouds of yellow sand.

Why should she care? The man was used to roughing it. He liked adventures. He was afraid of nothing, and nothing ever hurt him. But she did care. She seemed to feel the sting of the sharp grains of sand on cheeks and eyes.

She was sitting in her own room, as she was accustomed to do in the evening if she were not out on the veranda—the pretty room which Knight had extravagantly made possible for her, with chintzes and furnishings from the best shops in El Paso. On this evening, however, she set both doors wide open, one which led into the living room, another leading into a corridor or hall. She could not fail to hear her husband when he came, even if he left his noisy car at the garage and walked to the house.

A travelling clock on the mantelpiece—Constance Annesley-Seton's gift—struck nine. The girl looked up at the first stroke, wondering if serious accidents were likely to happen in sandstorms; and before the last note had ended she heard steps in the patio.

"He has come!" she thought, with a throb of relief which shamed her. But the step was not like Knight's. It was hurried and nervous; and as she told herself this there sounded a loud knock at the door.

There was an electric bell, which Knight had fitted up with his own hands, but it was not visible at night. No one except herself could hear this knocking, for the servants' quarters were at the far end of the bungalow. A little frightened, recalling stories of cattle thieves and things they had done, Annesley went into the hall.

"Who is there?" she cried, her face near the closed door, which locked itself in shutting. If a man's voice—the voice of a stranger—should reply in "Mex," or with a foreign accent, the girl did not intend to let him in. A man's voice did reply, but neither in "Mex" nor with a foreign accent. It said: "My name is Paul Van Vreck. Open quickly, please. I may be followed."

Annesley's heart jumped; but without hesitation she pulled back the latch, and as she opened the door a rush of sand-laden wind wrenched it from her hand. She staggered away as the door swung free, and there was just time to see a tall, thin figure slip in like a shadow before the light of the hanging-lamp blew out. The girl and the newcomer were in the dark save for a yellow ray that filtered into the hall from her room, but she saw him stoop to place a bag or bundle on the floor, and then, pulling the door to against the wind, slammed it shut with a click.

Having done this, the tall shadow bent to pick up what it had laid down.

"Thank you, Mrs. Donaldson, for letting me in," said the most charming voice Annesley had ever heard—more charming even than Knight's. "Evidently you've heard your husband mention me, or you might have kept me out there parleying, if you're alone, for these are stirring times."
