His father spoke scarcely at all during the meal, and, though it was not the habit of Lazarus to speak at such times unless spoken to, this evening it seemed to Marco that he _looked_ more silent than he had ever seen him look before. They were plainly both thinking anxiously of deeply serious things. The story of the stranger who had been to Samavia must not be told yet. But it was one which would keep. Loristan did not say anything until Lazarus had removed the things from the table and made the room as neat as possible. While that was being done, he sat with his forehead resting on his hand, as if absorbed in thought. Then he made a gesture to Marco. "Come here, Comrade," he said. Marco went to him. "To-night some one may come to talk with me about grave things," he said. "I think he will come, but I cannot be quite sure. It is important that he should know that, when he comes, he will find me quite alone. He will come at a late hour, and Lazarus will open the door quietly that no one may hear. It is important that no one should see him. Some one must go and walk on the opposite side of the street until he appears. Then the one who goes to give warning must cross the pavement before him and say in a low voice, 'The Lamp is lighted!' and at once turn quietly away." What boy's heart would not have leaped with joy at the mystery of it! Even a common and dull boy who knew nothing of Samavia would have felt jerky. Marco's voice almost shook with the thrill of his feeling. "How shall I know him?" he said at once. Without asking at all, he knew he was the "some one" who was to go. "You have seen him before," Loristan answered. "He is the man who drove in the carriage with the King." "I shall know him," said Marco. "When shall I go?" "Not until it is half-past one o'clock. Go to bed and sleep until Lazarus calls you." Then he added, "Look well at his face before you speak. He will probably not be dressed as well as he was when you saw him first."
