As we pushed our way through the group, I fancied that it closed around me ominously. The conductor said nothing, but led the way without ceremony to the side of the berth.

“What’s the matter?” I inquired. I was puzzled, but not apprehensive. “Have you some of my things? I’d be thankful even for my shoes; these are confoundedly tight.”

Nobody spoke, and I fell silent, too. For one of the pillows had been turned over, and the under side of the white case was streaked with brownish stains. I think it was a perceptible time before I realized that the stains were blood, and that the faces around were filled with suspicion and distrust.

“Why, it—that looks like blood,” I said vacuously. There was an incessant pounding in my ears, and the conductor’s voice came from far off.

“It is blood,” he asserted grimly.

I looked around with a dizzy attempt at nonchalance. “Even if it is,” I remonstrated, “surely you don’t suppose for a moment that I know anything about it!”

The amateur detective elbowed his way in. He had a scrap of transparent paper in his hand, and a pencil.

“I would like permission to trace the stains,” he began eagerly. “Also”—to me—“if you will kindly jab your finger with a pin—needle—anything—”

“If you don’t keep out of this,” the conductor said savagely, “I will do some jabbing myself. As for you, sir—” he turned to me. I was absolutely innocent, but I knew that I presented a typical picture of guilt; I was covered with cold sweat, and the pounding in my ears kept up dizzily. “As for you, sir—”

The irrepressible amateur detective made a quick pounce at the pillow and pushed back the cover. Before our incredulous eyes he drew out a narrow steel dirk which had been buried to the small cross that served as a head.
