A week had not passed before Marco brought to The Rat in their bedroom an envelope containing a number of slips of paper on each of which was written something.  
"This is another part of the game," he said gravely. "Let us sit down together by the table and study it."
 
They sat down and examined what was written on the slips. At the head of each was the name of one of the places with which Marco had connected a face he had sketched. Below were clear and concise directions as to how it was to be reached and the words to be said when each individual was encountered.
 
"This person is to be found at his stall in the market," was written of the vacant-faced peasant. "You will first attract his attention by asking the price of something. When he is looking at you, touch your left thumb lightly with the forefinger of your right hand. Then utter in a low distinct tone the words 'The Lamp is lighted.' That is all you are to do."
 
Sometimes the directions were not quite so simple, but they were all instructions of the same order. The originals of the sketches were to be sought out—always with precaution which should conceal that they were being sought at all, and always in such a manner as would cause an encounter to appear to be mere chance. Then certain words were to be uttered, but always without attracting the attention of any bystander or passer-by.
 
The boys worked at their task through the entire day. They concentrated all their powers upon it. They wrote and re-wrote—they repeated to each other what they committed to memory as if it were a lesson. Marco worked with the greater ease and more rapidly, because exercise of this order had been his practice and entertainment from his babyhood. The Rat, however, almost kept pace with him, as he had been born with a phenomenal memory and his eagerness and desire were a fury.
 
But throughout the entire day neither of them once referred to what they were doing as anything but "the game."
 
At night, it is true, each found himself lying awake and thinking. It was The Rat who broke the silence from his sofa.
 
"It is what the messengers of the Secret Party would be ordered to do when they were sent out to give the Sign for the Rising," he said. "I made that up the first day I invented the party, didn't I?"
 
"Yes," answered Marco.
 
After a third day's concentration they knew by heart everything given to them to learn. That night Loristan put them through an examination.
 
"Can you write these things?" he asked, after each had repeated them and emerged safely from all cross-questioning.
 
Each boy wrote them correctly from memory.
 
"Write yours in French—in German—in Russian—in Samavian," Loristan said to Marco.
 
"All you have told me to do and to learn is part of myself, Father," Marco said in the end. "It is part of me, as if it were my hand or my eyes—or my heart."
 
"I believe that is true," answered Loristan.
 
He was pale that night and there was a shadow on his face. His eyes held a great longing as they rested on Marco. It was a yearning which had a sort of dread in it.
 
Lazarus also did not seem quite himself. He was red instead of pale, and his movements were uncertain and restless. He cleared his throat nervously at intervals and more than once left his chair as if to look for something.
 
It was almost midnight when Loristan, standing near Marco, put his arm round his shoulders.
 
"The Game"—he began, and then was silent a few moments while Marco felt his arm tighten its hold. Both Marco and The Rat felt a hard quick beat in their breasts, and, because of this and because the pause seemed long, Marco spoke.
 
"The Game—yes, Father?" he said.
 
"The Game is about to give you work to do—both of you," Loristan answered.
 
Lazarus cleared his throat and walked to the easel in the corner of the room. But he only changed the position of a piece of drawing-paper on it and then came back.
 
"In two days you are to go to Paris—as you," to The Rat, "planned in the game."
 
"As I planned?" The Rat barely breathed the words.
 
"Yes," answered Loristan. "The instructions you have learned you will carry out. There is no more to be done than to manage to approach certain persons closely enough to be able to utter certain words to them."
 
"Only two young strollers whom no man could suspect," put in Lazarus in an astonishingly rough and shaky voice. "They could pass near the Emperor himself without danger. The young Master—" his voice became so hoarse that he was obligated to clear it loudly—"the young Master must carry himself less finely. It would be well to shuffle a little and slouch as if he were of the common people."
 
"Yes," said The Rat hastily. "He must do that. I can teach him. He holds his head and his shoulders like a gentleman. He must look like a street lad."
 
"I will look like one," said Marco, with determination.
 
"I will trust you to remind him," Loristan said to The Rat, and he said it with gravity. "That will be your charge."
 
As he lay upon his pillow that night, it seemed to Marco as if a load had lifted itself from his heart. It was the load of uncertainty and longing. He had so long borne the pain of feeling that he was too young to be allowed to serve in any way. His dreams had never been wild ones—they had in fact always been boyish and modest, howsoever romantic. But now no dream which could have passed through his brain would have seemed so wonderful as this—that the hour had come—the hour had come—and that he, Marco, was to be its messenger. He was to do no dramatic deed and be announced by no flourish of heralds. No one would know what he did. What he achieved could only be attained if he remained obscure and unknown and seemed to every one only a common ordinary boy who knew nothing whatever of important things. But his father had given to him a gift so splendid that he trembled with awe and joy as he thought of it. The Game had become real. He and The Rat were to carry with them The Sign, and it would be like carrying a tiny lamp to set aflame lights which would blaze from one mountain-top to another until half the world seemed on fire.
 
As he had awakened out of his sleep when Lazarus touched him, so he awakened in the middle of the night again. But he was not aroused by a touch. When he opened his eyes he knew it was a look which had penetrated his sleep—a look in the eyes of his father who was standing by his side. In the road outside there was the utter silence he had noticed the night of the Prince's first visit—the only light was that of the lamp in the street, but he could see Loristan's face clearly enough to know that the mere intensity of his gaze had awakened him. The Rat was sleeping profoundly. Loristan spoke in Samavian and under his breath.
 
"Beloved one," he said. "You are very young. Because I am your father—just at this hour I can feel nothing else. I have trained you for this through all the years of your life. I am proud of your young maturity and strength but—Beloved—you are a child! Can I do this thing!"
 
For the moment, his face and his voice were scarcely like his own.
 
He kneeled by the bedside, and, as he did it, Marco half sitting up caught his hand and held it hard against his breast.
 
"Father, I know!" he cried under his breath also. "It is true. I am a child but am I not a man also? You yourself said it. I always knew that you were teaching me to be one—for some reason. It was my secret that I knew it. I learned well because I never forgot it. And I learned. Did I not?"
 
He was so eager that he looked more like a boy than ever. But his young strength and courage were splendid to see. Loristan knew him through and through and read every boyish thought of his.
 
"Yes," he answered slowly. "You did your part—and now if I—drew back—you would feel that I had failed you—failed you."
 
"You!" Marco breathed it proudly. "You could not fail even the weakest thing in the world."
 
There was a moment's silence in which the two pairs of eyes dwelt on each other with the deepest meaning, and then Loristan rose to his feet.
 
"The end will be all that our hearts most wish," he said. "To-morrow you may begin the new part of 'the Game.' You may go to Paris."
 
When the train which was to meet the boat that crossed from Dover to Calais steamed out of the noisy Charing Cross Station, it carried in a third-class carriage two shabby boys. One of them would have been a handsome lad if he had not carried himself slouchingly and walked with a street lad's careless shuffling gait. The other was a cripple who moved slowly, and apparently with difficulty, on crutches. There was nothing remarkable or picturesque enough about them to attract attention. They sat in the corner of the carriage and neither talked much nor seemed to be particularly interested in the journey or each other. When they went on board the steamer, they were soon lost among the commoner passengers and in fact............
