Chance accomplished for them what no amount of careful execution might have done, and they came within the ruin unnoticed by the four who occupied the old, darkened library.

Possibly the fact that one of the men had himself just entered and was excitedly talking to the others may have drowned the noisy approach of the two. However that may be, it is a fact that Barney and the cavalry officer came to the very door of the library unheard.

There they halted, listening. Coblich was speaking.

“The Regent commands it, Maenck,” he was saying. “It is the only thing that can save our necks. He said that you had better be the one to do it, since it was your carelessness that permitted the fellow to escape from Blentz.”

Huddled in a far corner of the room was an abject figure trembling in terror. At the words of Coblich it staggered to its feet. It was the king.

“Have pity—have pity!” he cried. “Do not kill me, and I will go away where none will ever know that I live. You can tell Peter that I am dead. Tell him anything, only spare my life. Oh, why did I ever listen to the cursed fool who tempted me to think of regaining the crown that has brought me only misery and suffering—the crown that has now placed the sentence of death upon me.”

“Why not let him go?” suggested the trooper, who up to this time had not spoken. “If we don’t kill him, we can’t be hanged for his murder.”

“Don’t be too sure of that,” exclaimed Maenck. “If he goes away and never returns, what proof can we offer that we did not kill him, should we be charged with the crime? And if we let him go, and later he returns and gains his throne, he will see that we are hanged anyway for treason.

“The safest thing to do is to put him where he at least cannot come back to threaten us, and having done so upon the orders of Peter, let the king’s blood be upon Peter’s head. I, at least, shall obey my master, and let you two bear witness that I did the thing with my own hand.” So saying he drew his sword and crossed toward the king.

But Captain Ernst Maenck never reached his sovereign.
