Seven pounds! Elgert growled at that, but the note must be got again at any cost; and so Dobson was given the sum required, and dispatched upon his errand. He wanted Elgert to go with him, for company, but Elgert was too cunning for that. He had kept out of the business all along, and he did not mean to be seen in it now. To be sure, he had been with Dobson to inquire about it in the first place, but he had no fear that the man would betray him. Dobson had done the changing, and Dobson should do the buying, and bring the note back to him. "I cannot come," he said, in answer to the boy's remonstrance. "I expect our man over with a letter from my father, and I want to stay here to get it. You must go alone. It won't take you long. Hurry back, for I shall not go out until you return." "I always have to do the work," grumbled Dobson. "It is a horrid long way to go alone." "Get out! Have not I found the money? And as to a long way, you don't make much fuss about that if you think that you are going to be treated to tarts. You clear off, and look sharp; and thank your lucky stars that we have got out of the mess so nicely, for I confess that I did not think that we were going to manage it!" So Dobson set off, and Horace Elgert turned back to the playground, to await his return with what patience he could; and there the Head himself came upon him, and stopped, and placed one hand upon his shoulder, looking searchingly into his face. "I am glad that I have met you alone, Elgert," the doctor said. "For I want to speak to you very seriously. I want to speak to you about Charlton." "Yes, sir?" said the boy inquiringly. It was wonderful how calmly and innocently he spoke. "What about him, sir--has he owned that his story is false?" "Not so, Elgert. Nor am I satisfied that it is false, Elgert. Are you satisfied that it is?" "Why, sir, of course I am!" he answered, staring up as if unable to comprehend the Head's meaning, though he knew it well enough. "Elgert, there is an old Book with an old law, which says: 'Thou shalt not bear false witness against thy neighbour.' In face of such a solemn command, are you still sure that Charlton's story is false?" "You don't mean to say that I and Dobson were there taking those papers, do you, sir?" he queried indignantly. "Ah, I see how it is! You believe his word. I don't think that quite fair, sir. Consider the difference between his surroundings and mine. Which will most likely speak the truth--the son of a man wanted by the police, or the son of a nobleman like my father?" "You still adhere to your statement, Elgert?" said the Head, taking no notice of the latter part of his speech. And Elgert answered at once-- "Of course I do, sir!" "Then," said the Head, "I have no option but to be guided by circumstances, and they all point to Charlton being guilty." And with that he turned away.
