“Goodness! Never! Without looking us up and saying a word of good-bye?”

Dorothy got up with determination. “I am going to find out,” she said. “I feel that I would like to see Mr. Knapp again.”

“Well! if I said a thing like that about a young man——”

However, Tavia let the remark trail off into silence and followed her chum. As they came out of the dining-room the broad shoulders and broad-brimmed hat of Garry Knapp were going through the street door!

“Oh!” gasped Dorothy.

“He’s going!” added Tavia, stricken quite as motionless.

“Going——”

“Gone!” ended Tavia, sepulchrally. “It’s all off, Dorothy. Garry Knapp, of Desert City, has departed.”

“Oh, we must stop him—speak to him——”

Dorothy started for the door and Tavia, nothing loath, followed at a sharp pace. Just as they came out into the open street a car stopped before the hotel door and Garry Knapp, “bag and baggage” stepped aboard. He did not even look back!
