She had thought San Antonio charming the first time she saw it, but it seemed doubly so now that she came back to it, as one familiar with its principal streets and landmarks. The life, the color, the holiday air of the crowds, the fête day atmosphere of the old town itself, exhilarated her till her cheeks glowed like roses, and several times, both on the street and in the stores, she caught herself whistling half under her breath.

Although the usual Monday morning bargain hunters were out in throngs, she found no trouble in making her purchases. Everything seemed to be in her favor this morning. The shop girls were unusually responsive and helpful, showed her just what she wanted or suggested something better than she had thought of. Only once or twice did the prices go above the limit she had set for them, and several times they were lower. By quarter to twelve she had checked off two thirds of the articles on her list.

Elated by this success, she stood waiting at the transfer desk for her change, looking around with unabated interest. Suddenly her attention was attracted to a girl in a brown tailor suit, standing in the next aisle. Her back was turned towards Mary, but there was something familiar looking in the poise of the graceful head; something very familiar looking in the puffs of soft auburn-bronze hair held by amber combs, and arranged so becomingly under the big brown hat.

Mary had been on the look-out all morning for the girl whom Jack had recognized at the hotel as Gay Melville. She might have missed her had Gay been an ordinary blonde or brunette, but as Jack said, there was no mistaking that glorious hair. Snatching up the proffered change, which the cashier put through the cage window, she pushed her way into the next aisle. The girl turned. The big plumed hat drooped over her face, still Mary recognized the delicate profile, the slight tilt of the slender chin. It was an opportunity which she could not afford to lose, and as the girl turned her back again to receive a package held out to her by a clerk, and started slowly to the door, Mary hurried after her.

Almost breathless in her eagerness she exclaimed impulsively, "I beg your pardon—but aren't you Gay?"

There was an instant of freezing silence as the eyes of the girl in brown swept Mary from head to foot.

"Well, not particularly," was the indignant reply.

The roll of her r's emphasized Mary's mistake. It was evidently some stranger from the North whom she had accosted. One glance into her full face made Mary see how dire her mistake had been. There was no resemblance whatever in that to Gay. Wishing that she could drop out of sight through the floor, she hastily apologized and hurried out into the street, her cheeks burning, as she smarted under the recollection of the stranger's supercilious glance.

"She needn't have been so snippy," Mary thought. "Anybody is liable to make such mistakes."

Not until she had crossed the street and was stopped short by her own reflection in a mirror in the show window opposite, did she realize how her question might have sounded.
