Frank lowered his voice.
"I will come and see you to-morrow," he said, as he prepared to go.
At that moment there was the sound of several persons walking in the corridor. Then could be heard the voice of Dr. Hardman. He was showing a party of medical men through the place.
"You will find this up-to-date in every respect," he was saying. "I will just show you one of the patient's rooms," and he opened the door of the apartment where Frank was.
At the sight of the boy the head of the sanitarium looked much surprised. He knew there had been no excitement, and, in consequence, no excuse for Frank entering the room. Dr. Hardman glanced sharply at the boy, as Frank, putting on his glasses, hurried off down the corridor. But the physician said nothing, because visitors were present. Dr. Hardman went on explaining the system used at the sanitarium, but Frank, as he disappeared around a corner, felt that he would be dismissed as soon as the doctor was at liberty.
"Well, it's all over now," Frank thought "He recognized me and I've got to take the bull by the horns. However, I think I have things so arranged that I can carry out my plans without any trouble. I must get the boys to help me."
Fortunately for Frank, the visitors remained a long time. They stayed to dinner, and Dr. Hardman had to be with them. He had no chance to speak to Frank, though he sent a message by one of the attendants that the new boy was to go to the office, and wait there for the physician.
"If I go it means he'll dismiss me," thought Frank. "I'll keep out of his sight as long as I can. I must get a chance to enter room twenty-eight once more, to say that I am going away, but that I will carry out the plan of rescue. After that I will leave before Dr. Hardman gets a chance to discharge me, or ask questions."
But Frank's plans did not work out as he expected they would. He did manage to get to room twenty-eight again, at a time when that part of the building was deserted. Most of the patients had gone out for the usual afternoon exercise, but the one Frank wanted to see, had remained in.
He knocked at the door. It was opened on a crack, and a man peered out.
