Mary V leaned sidewise so that she too could watch him from where she sat at the table.

She was sure, when she saw him ride off, that he was the same man who had met Tex away back there in the arroyo.
She watched Johnny, wondering if he knew the man, or knew what was his real reason for coming.

Whatever his real reason was, he had gone off without stating it, and Mary V believed that he had gone because she was there.

She wished she knew why he had come, but she would not ask Johnny.
She merely watched him covertly.
Johnny had turned thoughtful.

He did not even see that Mary V was watching him, he was so busy wishing that she had not come at all, or that she had gone before this man rode up.
