"We can write a note and leave it under the door. Then we can leave a note for daddy. He'll be worried when he comes back and finds us gone. That's the best plan, Alice. Leave a note for Russ, and then you and I will try to find him. They may know at the studio where he has gone. Or he may be there yet."

"All right!" agreed Alice, after a moment's thought.


CHAPTER XXIII

THE MISSING MODEL

Two notes were quickly written. One was left on the table in the girls' apartment, telling their father that they were going out for a little while, to try to locate Russ on a matter of some importance connected with the moving pictures.

"There's no use telling daddy what has happened," said Alice. "He would only worry, and really there's no danger. We are merely going to warn Russ. He'll have to look after the men himself. But daddy would be sure to think we would get into some trouble. So we may as well not bother him."

"All right!" agreed Ruth. She was entering into the spirit of the affair now. Her eyes were shining and her cheeks vied in hue with those of Alice.

The other note, marked "Urgent!" was thrust under the kitchen door of the Dalwood flat.

"They'll be sure to see that," remarked Alice. "And, no matter if only Billy comes home first, he'll know what to do," for the story of the men's talk in the restaurant had been briefly set down on the paper.
