"A motor-car isn't the best place for talking secrets," he laughed.
"But I won't peep!"
"I haven't let any cat out!" retorted Miss Crilly.
She and David tossed merry sallies back and forth; but Polly was uncomfortable. David would think she did not trust him. She wished Miss Crilly had not referred to the matter.
"Come on down to dinner!" invited David, after they had said good-bye to Miss Sterling and Miss Crilly.
"Oh, I'd love to!" beamed Polly. "I'll run in and ask mother."
He hailed his uncle's chauffeur, and bade him wait.
In a moment she was back and they stepped into Colonel Gresham's car.
"I am going to share my secret with you," David smiled, glancing doubtfully at the man ahead.
"Otto," he said tentatively, without raising his voice above the tone he had used for Polly. The man did not stir. "Otto," a little louder. No answer.
He nodded complacently. "I wanted to make sure of him," he smiled.
"Now I'll go on."
