"I'm in charge of him," declared the Secret Service man.
"I happen to know Mr. Middlecrease as a resident of Trebalda," observed the medical man drily; "and I was not aware that he was in any one's charge."
"Look here," exclaimed Entwistle, drawing the doctor aside. "You've forced my hand, so to speak. This man, Middlecrease, is under arrest as a noted German spy. Naturally I don't want the Greenwoods to know anything about it at present; and still less do I want them to have a Hun in their house, especially as he might take it into his head to vanish during the night."
"Bless my soul, you surprise me!" ejaculated the doctor. "What do you want me to do?"
"To order his removal to a nursing establishment in Trebalda," replied the Secret Service man. "I'll keep my eye on him there. Also, I know I can rely upon your silence."
"Very good," was the reply. "I'll send a motor ambulance along at—what time?"
"Say eight," rejoined Entwistle. "That will leave ample time for our little adventure, Mr. Farrar."
