“Right,” Ken told him. “At least they don’t give it to anybody but the police. And Barrack’s no policeman.”
“Then how did he know how to find us,” Sandy asked, “without telephoning first?”
“Probably,” Ken said slowly, “because he’d been here before—looking for the box.”
CHAPTER VII
AN EXPLODED THEORY
Sandy repeated Ken’s last words in a sort of daze. “He’d been here before looking for the box?” He shook his head to clear it. “You mean the night your father got back? When the door was found open in the morning? You think Barrack was here then?”
Ken nodded. “Barrack or somebody involved with him. How else would he have known this address?”
Sandy shrugged. “He might have learned it in a hundred different ways. But suppose for a minute you’re right. In that case why would he come back here now? Why wouldn’t he avoid us?”
“He probably wanted to find out how much we know—or suspect,” Ken said.
