"While you have been sleeping many things have trans-pired within the walls of your castle. The king's troopers have departed; but that is a small matter compared with the other. Here, behind the portrait of your great-grand-mother, I have listened and watched all night. I opened the secret door a fraction of an inch--just enough to permit me to look into the apartment where the king and the American lay wounded. They had been talking as I opened the door, but after that they ceased--the king falling asleep at once--the American feigning slumber. For a long time I watched, but nothing happened until near midnight. Then the Ameri-can arose and donned the king's clothes.

"He approached Leopold with drawn sword, but when he would have thrust it through the heart of the sleeping man his nerve failed him. Then he stole some papers from the room and left. Just now he has ridden out toward Lustadt with the men of the Royal Horse who captured the castle yesterday."Before Maenck was half-way through his narrative, Peter of Blentz was wide awake and all attention. His eyes glowed with suddenly aroused interest.

"Somewhere in this, prince," concluded Maenck, "there must lie the seed of fortune for you and me."Peter nodded. "Yes," he mused, "there must."For a time both men were buried in thought. Suddenly Maenck snapped his fingers. "I have it!" he cried. He bent toward Prince Peter's ear and whispered his plan. When he was done the Blentz prince grasped his hand.

"Just the thing, Maenck!" he cried. "Just the thing. Leo-pold will never again listen to idle gossip directed against our loyalty. If I know him--and who should know him better--he will heap honors upon you, my Maenck; and as for me, he will at least forgive me and take me back into his confidence. Lose no time now, my friend. We are free now to go and come, since the king's soldiers have been withdrawn."In the garden back of the castle an old man was busy digging a hole. It was a long, narrow hole, and, when it was completed, nearly four feet deep. It looked like a grave.

When he had finished the old man hobbled to a shed that leaned against the south wall. Here were boards, tools, and a bench. It was the castle workshop. The old man selected a number of rough pine boards. These he measured and sawed, fitted and nailed, working all the balance of the night. By dawn, he had a long, narrow box, just a trifle smaller than the hole he had dug in the garden. The box resembled a crude coffin. When it was quite finished, in-cluding a cover, he dragged it out into the garden and set it upon two boards that spanned the hole, so that it rested precisely over the excavation.

All these precautions methodically made, he returned to the castle. In a little storeroom he searched for and found an ax. With his thumb he felt of the edge--for an ax it was marvelously sharp. The old fellow grinned and shook his head, as one who appreciates in anticipation the consumma-tion of a good joke. Then he crept noiselessly through the castle's corridors and up the spiral stairway in the north tower. In one hand was the sharp ax.

The moment Lieutenant Butzow had reached Lustadt he had gone directly to Prince von der Tann; but the moment his message had been delivered to the chancellor he sought out the chancellor's daughter, to tell her all that had oc-curred at Blentz.

"I saw but little of Mr. Custer," he said. "He was very quiet. I think all that he has been through has unnerved him. He was slightly wounded in the left leg. The king was wounded in the breast. His majesty conducted himself in a most valiant and generous manner. Wounded, he lay upon his stomach in the courtyard of the castle and defended Mr. Custer, who was, of course, unarmed. The king shot three of Prince Peter's soldiers who were attempting to assassinate Mr. Custer."Emma von der Tann smiled. It was evident that Lieuten-ant Butzow had not discovered the deception that had been practiced upon him in common with all Lutha--she being the only exception. It seemed incredible that this good friend of the American had not seen in the heroism of the man who wore the king's clothes the attributes and ear-marks of Bar-ney Custer. She glowed with pride at the narration of his heroism, though she suffered with him because of his wound.

It was not yet noon when the detachment of the Royal Horse arrived in Lustadt from Blentz. At their head rode one whom all upon the streets of the capital greeted enthusi-astically as king. The party rode directly to the royal palace, and the king retired immediately to his apartments. A half hour later an officer of the king's household knocked upon the door of the Princess Emma von der Tann's boudoir. In accord with her summons he entered, saluted respectfully, and handed her a note.

It was written upon the personal stationary of Leopold of Lutha. The girl read and reread it. For some time she could not seem to grasp the enormity of the thing that had over-whelmed her--the daring of the action that the message explained. The note was short and to the point, and was signed only with initials.

DEAREST EMMA:

The king died of his wounds just before midnight. Ishall keep the throne. There is no other way. None knows and none must ever know the truth. Your father alone may suspect; but if we are married at once our alliance will cement him and his faction to us. Send word by the bearer that you agree with the wisdom of my plan, and that we may be wed at once--this afternoon, in fact.
