"You don't know what she is to tell Heinrich and where she is to be to-night?"
"No, sir," said Bob. "That's all I heard."
"Well," exclaimed Mr. Cook after a moment's pause. "This is a nice state of affairs."
"What are you going to do about it?" asked Bob. "Are you still going to wait until to-morrow before you report Heinie to the police?"
Mr. Cook passed his hand across his brow as if to wipe away the doubts that assailed him. "Heinrich and Lena both," he muttered. "What a pity."
"I tell you what I'll do," he exclaimed finally. "I'll take Heinrich along with me to-night just as I planned, and I'll tell your mother under no conditions to let Lena go out this evening. In the morning we may know better what to do."
"I have a better scheme than that," said Bob eagerly.
"Tell me what it is."
"Take Heinrich along with you and watch him all the time; that part is all right. But let Lena go out if she wants to."
"What's the point of that?" demanded his father. "For all we know Lena may he able to do more harm than Heinrich; certainly she's smarter."
