It was after the policeman had walked round his beat and disappeared for the third time, that Marco heard footsteps echoing at some distance down a cross street. After listening to make sure that they were approaching instead of receding in another direction, he placed himself at a point where he could watch the length of the thoroughfare. Yes, some one was coming. It was a man's figure again. He was able to place himself rather in the shadow so that the person approaching would not see that he was being watched. The solitary walker reached a recognizable distance in about two minutes' time. He was dressed in an ordinary shop-made suit of clothes which was rather shabby and quite unnoticeable in its appearance. His common hat was worn so that it rather shaded his face. But even before he had crossed to Marco's side of the road, the boy had clearly recognized him. It was the man who had driven with the King!

Chance was with Marco. The man crossed at exactly the place which made it easy for the boy to step lightly from behind him, walk a few paces by his side, and then pass directly before him across the pavement, glancing quietly up into his face as he said in a low voice but distinctly, the words "The Lamp is lighted," and without pausing a second walk on his way down the road. He did not slacken his pace or look back until he was some distance away. Then he glanced over his shoulder, and saw that the figure had crossed the street and was inside the railings. It was all right. His father would not be disappointed. The great man had come.

He walked for about ten minutes, and then went home and to bed. But he was obliged to tell himself to go to sleep several times before his eyes closed for the rest of the night.

AN EXCITING GAME

Loristan referred only once during the next day to what had happened.

"You did your errand well. You were not hurried or nervous," he said. "The Prince was pleased with your calmness."

No more was said. Marco knew that the quiet mention of the stranger's title had been made merely as a designation. If it was necessary to mention him again in the future, he could be referred to as "the Prince." In various Continental countries there were many princes who were not royal or even serene highnesses—who were merely princes as other nobles were dukes or barons. Nothing special was revealed when a man was spoken of as a prince. But though nothing was said on the subject of the incident, it was plain that much work was being done by Loristan and Lazarus. The sitting-room door was locked, and the maps and documents, usually kept in the iron box, were being used.

Marco went to the Tower of London and spent part of the day in living again the stories which, centuries past, had been inclosed within its massive and ancient stone walls. In this way, he had throughout boyhood become intimate with people who to most boys seemed only the unreal creatures who professed to be alive in school-books of history. He had learned to know them as men and women because he had stood in the palaces they had been born in and had played in as children, had died in at the end. He had seen the dungeons they had been imprisoned in, the blocks on which they had laid their heads, the battlements on which they had fought to defend their fortressed towers, the thrones they had sat upon, the crowns they had worn, and the jeweled scepters they had held. He had stood before their portraits and had gazed curiously at their "Robes of Investiture," sewn with tens of thousands of seed-pearls. To look at a man's face and feel his pictured eyes follow you as you move away from him, to see the strangely splendid garments he once warmed with his living flesh, is to realize that history is not a mere lesson in a school-book, but is a relation of the life stories of men and women who saw strange and splendid days, and sometimes suffered strange and terrible things.
