Rupert read the letter through two or three times, then ran down as he was, in his night-shirt and trousers, and passed in to the master's part of the private house. "Robert," he said to the man-servant whom he met in the passage, "is Mr. River-Smith dressed yet?"
"He is not finished dressing yet, Master Clinton; at least he has not come out of his room. But I expect he is pretty near dressed."
"Will you ask him to come out to me at once, please?" Rupert said. "It is a most serious business, or you may be sure I should not ask."
The man asked no questions, for he saw by Rupert's face that this must be something quite out of the ordinary way. "Just step into this room and I will fetch him," he said.
In a minute the master came in. "What is it, Clinton,--nothing serious the matter, I hope?"
"Yes, sir, I am afraid it is something very serious. My brother was not well yesterday evening. He said that he had a frightful headache, but he thought it would be all right in the morning, and he went and lay down on his bed. I thought that he was strange in his manner when I went in to say good-night to him; and when I went in this morning, sir, the bed hadn't been slept in and he was gone, and he has left me this note, and it is evident, as you will see, that he is altogether off his head. You see, he fancies that he is not my brother."
The master had listened with the gravest concern, and now glanced hastily through the letter.
"'Tis strange indeed," he said. "There is no possibility, of course, that there is anything in this idea of his?"
"No, sir, of course not. How could there be?"
"That I cannot say, Clinton. Anyhow the matter is most serious. Of course he could not have taken any clothes with him?"
"No, sir; at least he cannot have got any beyond what he stands in. I should think the matron would not have given him any out, especially as he must have told her that he was ill, or he could not have got into the dormitory."
"I had better see her first, Clinton; it is always well to be quite sure of one's ground. You go up and dress while I make the inquiries."
Rupert returned to the dormitory, finished dressing, and then ran down again. "He has taken no clothes with him, Clinton. The matron says that he went to her in the afternoon and said that he had a splitting headache, and wanted to be quite quiet and undisturbed. She offered to send for the doctor, but he said that he expected that he should be all right in the morning, but that if he wasn't of course the doctor could see him then. So she unlocked the door of the dormitory and let him in. I asked her if he had his boots on. She said no; he was going up in them, contrary to rule, when she reminded him of it, and he took them off and put them in the rack in the wood-closet. I have seen the boot-boy, and he says he noticed when he went there this morning early to clean them, No. 6 rack was empty. So your brother must have come down, after he had gone up to the dormitory, and got his boots.
