And what business had he, Rupert Winter, who had supposed himself to be an honorable man, who had sworn to support the Constitution and the laws of the United States, what business had he to help law-breakers and murderers escape the just punishment of their deeds? He almost ground his teeth. Oh, well, there was one way out, and that was to resign his commission. He would do it this very night, he resolved; and he swore miserably at himself, at his venerable aunt who must be protected at such a sacrifice, at Atkins, at the feebly moaning wretch whom he had not ceased all this while to ply carefully with drops of brandy. “You everlasting man-eater, if you dare to die, I’ll kill you!” he snorted.

Thereupon he went at the puzzle again. Before any answer could come to the telephone calls, a low, mournful, inhuman cry penetrated the thick walls. It was repeated thrice; on the third call, Tracy ran quickly through the patio to a side door, barred and locked like all the entrances, released and swung it open and let in Kito. A few murmured words passed between them. The Jap uttered a startled exclamation. “But how can it to be? How? no one can get in! And who shall stab him? For why?”

He examined the wounded man, after a gravely courteous salute to Winter; and frowned and sighed. “What did it?” said he; “did who stabbed, take it ’way, he must give stlong pull!”

“Whoever did it,” said the colonel, “must have put a knee on the man’s back and pulled a strong pull, as you say.” In speaking the words he felt a shiver, for he seemed to see that red smear above Mercer’s knee.

He felt the shiver again when Mercer returned and he glanced at him; there was not a stain on his shining white cuffs; he had changed them; he had also changed his suit of clothes and his shoes. His eyes met the colonel’s; and Winter fancied there was a glint of defiance in them; he made no comment, for no doubt a plausible excuse for the fresh clothes was ready. Well, he (Winter) wouldn’t ask it. Poor devil! he had had provocation.

For the next half-hour they were all busy with Keatcham.

“He is better,” pronounced the Jap; “he will not live, maybe, but he will talk, he can say who hult him.”

“If he can only do that!” cried Mercer. “It is infernal to think any one can get in here and do such a thing!”

“Rotten,” Tracy moaned.

The colonel said nothing.
