Slowly the group settled in a dense ring about some one who was talking rapidly. Evidently the survivor of the tragedy was explaining. Was it the interpreter or the other? Johnny could not crowd close enough to tell.

He flashed his electric torch upon the fallen body. The sight of the hilt protruding from the chest, over the heart, gave Johnny a start. His interpreter had won. It was his knife that had made the fatal thrust. The dead man was undoubtedly Oriental and not a member of the Mongolian tribe.

That knife! Johnny started. How had this person come into possession of that blade which he had given to Cio-Cio-San? That Cio-Cio-San would not give it away, he was certain. What then had happened? Had it been stolen from her, or was this strange interpreter, who had doubtless just now saved his life, Cio-Cio-San herself? It seemed unbelievable, yet his mind clung to the theory. He would soon know.

Slowly the crowd dispersed. The killing of an Oriental in such a camp as this was merely an incident in the life of the tribe, a thing soon to be forgotten. Two servants of the chief bore the body away. Once more Johnny found himself sitting in the triangle with his interpreter and the Mongol. In his hands he held two knives; one he had drawn from the heart of the dead man and had cleansed in the snow; the other was the one dropped by the murderer. This last one evidently had been meant for him.

The Mongol was profuse in his apologies, while he lauded to the sky the bravery of the little interpreter. The slain man, he explained, was no member of his company. He was one of three who had camped on the outer edge of the village that very night. Doubtless they had followed Johnny with the purpose of murdering and robbing him. He had sent at once for the other two men, but they had fled. He hoped now that his guests might sleep in peace.

After delivering this message, he bowed himself back through the curtains. Johnny and the interpreter were left alone. It was a dramatic moment. The interpreter’s fingers twitched nervously. Once the brown eyes fell upon the knives Johnny held, but instantly they flashed away. Johnny had drawn a freshly lighted fish-oil lamp to his side.

“Friend,” said he in a low tone, “you have done me a great service this night. Will you do me but one more?”

“Gladly, most gracious one.”

The small head bent low.

“Allow me.” Johnny took one of the brown hands, and began rolling up the loose sleeve of the brown-skin parka. The brown face blanched a trifle. He uncovered a sleeve of pink silk, and beneath that a slender brown arm. On the arm, a finger’s length beneath the elbow, was a triangular scar.
