They came out of the house together and joined Mr. Hammond and Miss Gray just as they were about to step into the limousine. Aunt Alvirah waved her hand from the window.
"She's just lovely!" declared Miss Gray. "You should have met her, Mr. Hammond."
"That pleasure is in reserve," said the gentleman, smiling. "I hope to see the Red Mill again."
Tom came hurrying down to shake hands with Miss Gray. Ruth watched them with some puzzlement of mind. Tom was undoubtedly embarrassed; but the moving picture girl was too used to making an impression upon susceptible minds to be much disturbed by Tom Cameron's worship.
Mr. Hammond looked out of the door of the limousine before he closed it.
"Remember, Ruth Fielding, I shall be on the lookout for what you promised me."
"Oh, yes, sir!" Ruth cried, all in a flutter, for the moment having forgotten the scenario she proposed to write.
"That's a promise!" he said again gaily, and closed the door. The big car rolled away and left the three friends at the gateway.
"What's a promise, Ruth Fielding?" demanded her chum, with immense curiosity.
Ruth blushed and showed some confusion. "It's—it's a secret," she stammered.
