Why, if this little brother of his had not died, had he disappeared? And what was the reason for his disappearance? 'He did not die,' said the half-finished letter which his mother's hand had traced; 'he did not die.' Once, in the middle of the night, as he said the wearisome sentence over to himself, a word had come suddenly before him in letters of flame, and Peter had turned away from it with a cry. A child who had been deprived of his life might be said in a sense not to have died, and there was the word of six letters in front of him in the dark. He turned on the electric light in his cabin, and for a moment he had half a mind to go in next door and wake Toffy. The burden of the suggestion was too horrible to bear alone. 'He did not die!' His mother's mental state might not have been perfectly sound at the time of her husband's death; and her preference for him, Peter, was a fact that had been remarked by all who knew her. Had she begun to write a confession to her son, and stopped short in the middle? 'Don't hate me too much,' the letter said. Why should he hate her? He did not know. In the morning he was able to put aside utterly the thought which had tormented him, but he lived in dread of being beset by it at night-time again. He began to fear going to bed, and would sit up talking to Toffy till the small hours of the morning, or playing picquet with Dunbar. Men began to say that he 'jawed' too much and would not let them go to bed, little knowing how he used to try to prolong a conversation so that he might not be left alone with a horrible fear always ready to pounce upon him when night fell, and when only the thud of the engines playing some maddening tune broke the silence. He tried, with a baffling sense of impatience, to make his own memory act, and to recall the days when he was not quite three years old. But the thing was an impossibility, of course, and his brain refused to give up a single picture of that time. It was only when the ship had left St. Vincent that a certain amount of peace came to establish itself in his heart, and the large and beautiful consolation of the sea began to make itself felt. The weather was calm and clear, and the monotonous slap and swish of the water against the ship's side was in itself soothing. The company on board were all strangers to him, and this helped to give him a feeling that he was starting anew in life. Also he was on his way to do the best he could to find his brother, if he were living, or to clear up the mystery of his death, if he were dead. There was no horrid feeling of having failed to do the best that was possible. He must find Edward Ogilvie, or discover the grave where he lay; and after that it would be time enough to think what would be the next thing to do.
