“Promise me one thing,” she said. “Let me know as soon as your father returns-that is, if he has any news.”
“I’ll do that, Mrs. Robinson,” Frank agreed. “I know what this suspense must be like for you and the twins.”
“It’s terrible. But as long as Fenton Hardy-and his sons-are working on the case, I’m sure it will be straightened out.”
Callie and Frank were unusually silent all the way home. They had been profoundly affected by the change that the Tower Mansion mystery had caused in the lives of the Robinsons. Callie lived but a few blocks from the Hardy home, and Frank accompanied her to the door.
“See you tomorrow,” he said.
“Yes, Frank. And I hope you’ll hear good news from your father.”
The boy quickened his steps and ran eagerly into the Hardy house. Joe met him.
“Any phone call?”
Joe shook his head. “Mother’s pretty worried that something has happened to Dad.”
