But before the driver of the car could get down and open the door for her to get out a boy with a bicycle slid up to the curb and touching his gilt-buttoned cap respectfully said: "Excuse me, Miss, but Mr. Barnard sent me after you. He says there's been some mistake and you'll have to come back and get it corrected."

"Oh!" said Shirley, too surprised to think for a minute. "Oh! Then please hurry, for Mr. Barnard wants to get back in time to get that four-o'clock train."

The driver frowned, but the boy stepped up and handed him something, saying: "That's all right, Joe, he sent you this." The driver's face cleared and he started his machine again. The boy vanished into the throng. It was another of Shirley's after-memories that she had caught a glimpse of a scrap of paper along with the money the boy had handed the driver, and that he had stuffed it in his pocket after looking intently at it; but at the time she thought nothing of it. She was only glad that they were skimming along rapidly.
