“We can do nothing here, at any rate,” agreed Serge.

“You will come to dinner with us, won’t you?” Terry asked. “Mother expects you. There is no place in town where you can get anything worth eating.”

“You are sure it won’t be too much trouble? I did not expect it, you know,” Serge answered, smiling.

“Of course not,” Terry insisted. “You have to get your car, anyway.”

The water of the bay was as smooth as glass as they rowed away, the girls looking back wistfully as they left the houseboat behind.

Terry’s mother had a delicious meal waiting, and after so much excitement and activity the girls felt very hungry.

The conversation naturally centered about the disappearance of Dimitri. They discussed it from all angles. It was during a lull in the talk that Terry gave a little scream.

“What’s the matter?” Arden asked at once.

“Nothing,” Terry answered. “I saw a face at the window, and it made me jump. But it’s only Melissa again.”
