THE DOCTOR RIDES Hank Dwight disappeared from the doorway and the doctor was called from his pondering by the voice of the girl.

There was something about that voice which worried Byrne, for it was low and controlled and musical and it did not fit with the nasal harshness of the cattlemen.

When she began to speak it was like the beginning of a song.

He turned now and found her sitting a tall bay horse, and she led a red-roan mare beside her.
When he went out she tossed her reins over the head of her horse and strapped his valise behind her saddle.
"You won't have any trouble with that mare," she assured him, when the time came for mounting.

Yet when he approached gingerly he was received with flattened ears and a snort of anger.
