“Would they wish to be taken alive?”

“They would not promise to take steps to prevent it. They would not lay hands on their own lives. Their consciences would not permit it. Of course, it is all over now, and we need not speak of such dreadful things. But what would you have done in my place?”

“Kill them.”

“Mein Gott! You would murder them?”

“In mercy I would kill them. Man, I have been through it. I have seen the death of the hot eggs; I have seen the death of the boiling kettle; I have seen the women—my God! I wonder that I have ever slept sound again.” His usually impassive face was working and quivering with the agony of the remembrance. “I was strapped to a stake with thorns in my eyelids to keep them open, and my grief at their torture was a less thing than my self-reproach when I thought that I could with one tube of tasteless tablets have snatched them at the last instant from the hands of their tormentors. Murder! I am ready to stand at the Divine bar and answer for a thousand murders such as that! Sin! Why, it is such an act as might well cleanse the stain of real sin from the soul. But if, knowing what I do, I should have failed this second time to do it, then, by Heaven! there is no hell deep enough or hot enough to receive my guilty craven spirit.”

The Colonel rose, and again his hand clasped that of the Professor.

“You speak sense,” said he. “You are a brave, strong man, who know your own mind. Yes, by the Lord! you would have been my great help had things gone the other way. I have often thought and wondered in the dark, early hours of the morning, but I did not know how to do it. But we should have heard Ainslie’s shots before now; I will go and see.”

Again the old scientist sat alone with his thoughts. Finally, as neither the guns of the relieving force nor yet the signal of their approach sounded upon his ears, he rose, and was about to go himself upon the ramparts to make inquiry when the door flew open, and Colonel Dresler staggered into the room. His face was of a ghastly yellow-white, and his chest heaved like that of a man exhausted with running. There was brandy on the side-table, and he gulped down a glassful. Then he dropped heavily into a chair.

“Well,” said the Professor, coldly, “they are not coming?”

“No, they cannot come.”
