"I can't imagine a man plotting such things," said Bob bitterly. "He thinks he's helping Germany I suppose."

"Huh," snorted Bob. "A nice kind of man that will earn his living in a country and then try to blow it up. Is he going to get well?"

"The doctors say he has an even chance," said Sergeant Riley.

"Well, all I hope is," said Bob, "that when he does get well they take him and put him in jail for about fifteen years. Have you got plenty of guards, father?"

"I think so," said Mr. Cook. "I've got all I can get anyway."

"Hugh and I are ready to help you know."

"I know it, and I may use you later to-night; we will need them more then probably. In the meantime why don't you go and lie down for a little while?"

"We've got a paper here to be translated first," said Bob.

"Give it to me," exclaimed Mr. Cook. "I'll call Heinrich in."

In response to his summons Heinrich soon appeared from the next room. He looked pale and haggard as though he was tired and worn and worried. He glanced from one to another of the people gathered around the desk, but even his old pals, Bob and Hugh, gave him no more than a fleeting smile.
