The doctor's prediction was correct.
Todham Todd, completely restored in memory, was able to leave the hospital before the week was out. The reunion between the man and his sister was an affectionate one. The professor had not the slightest inkling of all the strange events that had transpired from the time of the first accident until he woke up in the hospital at Bayport. He was deeply puzzled when he learned where he was, but the doctor covered up his bewilderment by explaining that his case had been so unusual that he had been brought there for special treatment when the doctors of his home city had failed to bring him back to consciousness.
He was introduced to the Hardy boys by Miss Todd, who was pathetically grateful to the lads for restoring her brother to her, safe and sound again. But there was no sign of recognition. Seeing the boys struck no responsive chord in Professor Todd's memory. He knew nothing of the days when he had played at being Captain Royal. To all intents and purposes, he was seeing the Hardy boys for the first time.
They were content to let it remain at that and were careful to say nothing that might indicate they had known him previously. And when Todham Todd finally left the hospital and went to the hotel where his sister was staying, to rest there a few days before going back home, the Hardy boys were his firm friends.
"We must never let him know," said Evangeline Todd to the boys that evening.
"You may rely on us, Miss Todd," they assured her.
"I can't tell you how grateful I am," she said. "If you boys had not been shrewd enough to think that Captain Royal might be Todham Todd after all, things might not have turned out as they have. You might not have concerned yourselves with him any more, and he might still be living that wretched life in the caves. I want to reward your father and yourselves for finding him."
But Fenton Hardy had already expressed himself on the subject of the reward.
"I want nothing," he said. "You have already paid any expenses I incurred in trying to trace Mr. Todd. As for finding him, the credit belongs to the boys."
But the Hardy boys were insistent in their refusal.
