“The plot thickens,” murmurs the investigator excitedly, conning over the laconic cipher. “Having established the relationship between the forked pine and Ma-i-pah, otherwise the Red Peak, the next thing is to discover the blasted tree, which should not be difficult, unless the term represents obloquy rather than the effects of lightning. That done, the rest will be easy.”

A few steps further into the brake. Suddenly the blood surges into his face. Something white and ghostlike glints athwart the gloom. A huge pine, dead, and stripped of all its lower bark, clearly by several successive strokes of lightning. This can be no other than the “blasted tree” of the cipher. Almost trembling with excitement, once more he unfolds the dirty sheet of paper and eagerly scans it.

“Hands up, stranger! Hands up! or you’re a stiff ’un, by God!”

The harsh, threatening voice, cleaving the twilight solitude, where a moment before Vipan had imagined himself absolutely alone, was enough to unnerve a less resolute hearer. It proceeded from a tall, sinister-looking man, who standing on a ridge or bank some five-and-twenty yards off, and slightly above him, had him covered with a rifle-barrel. There was no disputing the grim mandate. The other held him at a complete disadvantage. Any hesitation to comply would mean a bullet through his heart that instant. But while holding both hands high above his head, his eyes were keenly on the look-out for the smallest chance.

“I don’t seem to have the pleasure of your acquaintance, friend,” he answered coolly. What a fool he was to have parted company with his Winchester, he thought.

“You don’t?” yelled the man, amid a volley of curses. “You soon will, though, I reckon, you pesky-white Injun. I’ll learn you to set the red devils on to scalp and knife my pardners. Now, you jest throw down that hunk of paper, slicker nor greased lightning—mind me.”

The tone was so fierce and threatening that there was no room for delay. No man living was more keenly competent to realise the situation than he who had now the worst of it.

“All right,” he answered. “I’m standing on it. You’ll see it when I move my foot.”

“Don’t move a hair else then, or you’re a stiff,” was the grim uncompromising reply.

“Now,” went on the fellow, having assured himself that the paper was there, “take six steps backward—six and no more. Quick march!”
