The pine needles hung wholly motionless above his head; but yet the dead leaves on which he knelt crinkled and rustled under him. Only the keenest ear could have heard the sound; and possibly in his madness, Cranston himself was not aware of it. And one would have wondered a long time as to what caused it. It was simply that he was shivering all over with hate and fury.

A twig cracked, far on the ridge above him. He leaned forward, peering, and the moonlight showed his face in unsparing detail. It revealed the deep lines, the terrible, drawn lips, the ugly hair long over the dark ears. His strong hands tightened upon the breech of the rifle. His wiry figure grew tense.

Of course it wouldn't do to let his prey come too close. Landy Hildreth was a good shot too, young as Cranston, and of equal strength; and no sporting chance could be taken in this hunting. Cranston had no intention of giving his enemy even the slightest chance to defend himself. If Hildreth got down into the valley, his testimony would make short work of the arson ring. He had the goods; he had been a member of the disreputable crowd himself.

The man's steps were quite distinct by now. Cranston heard him fighting his way through the brush thickets, and once a flock of grouse, frightened from their perches by the approaching figure, flew down the trail in front. Cranston pressed back the hammer of his rifle. The click sounded loud in the silence. He had grown tense and still, and the leaves no longer rustled.

His eyes were intent on a little clearing, possibly one hundred yards up the trail. The trail itself went straight through it. And in an instant more, Hildreth pushed through the buckbrush and stood revealed in the moonlight.

If there is one quality that means success in the mountains it is constant, unceasing self-control. Cranston thought that he had it. He had known the hard schools of the hills; and he thought no circumstance could break the rigid discipline in which his mind and nerves held his muscles. But perhaps he had waited too long for Hildreth to come; and the strain had told on him. He had sworn to take no false steps; that every motion he made should be cool and sure. He didn't want to attract Hildreth's attention by any sudden movement. All must be cautious and stealthy. But in spite of all these good resolutions, Cranston's gun simply leaped to his shoulder in one convulsive motion at the first glimpse of his enemy as he emerged into the moonlight.

The end of the barrel struck a branch of the shrubbery as it went up. It was only a soft sound; but in the utter silence it traveled far. But a noise in the brush might not have been enough in itself to alarm Hildreth. A deer springing up in the trail, or even a lesser creature, might make as pronounced a sound. It was true that even unaccompanied by any other suspicious circumstances, the man would have become instantly alert and watchful; but it was extremely doubtful that his muscular reaction would have been the same. But the gun barrel caught the moonlight as it leaped, and Hildreth saw its glint in the darkness.

It was only a flash. But yet there is no other object in the material world that glints exactly like a gun barrel in the light. It has a look all its own. It is even more distinctive in the sunlight, and now and again men have owed their lives to a momentary glitter across a half-mile of forest. Of course the ordinary, peaceful, God-fearing man, walking down a trail at night, likely would not have given the gleam more than an instant's thought, a momentary breathlessness in which the throat closes and the muscles set; and it is more than probable that the sleeping senses would not have interpreted it at all. But Hildreth was looking for trouble. He had dreaded this long walk to the settlements more than any experience of his life. He didn't know why the letter he had written, asking for an armed escort down to the courts, had not brought results. But it was wholly possible that Cranston would have answered this question for him. This same letter had fallen into a certain soiled, deadly pair of hands which was the last place in the world that Hildreth would have chosen, and it had been all the evidence that was needed, at the meeting of the ring the night before, to adjudge Hildreth a merciless and immediate end. Hildreth would have preferred to wait in the hills and possibly to write another letter, but a chill that kept growing at his finger tips forbade it. And all these things combined to stretch his nerves almost to the breaking point as he stole along the moonlit trail under the pines.

A moment before the rush and whir of the grouse flock had dried the roof of his mouth with terror. The tall trees appalled him, the shadows fell upon his spirit. And when he heard this final sound, when he saw the glint that might so easily have been a gun-barrel, his nerves and muscles reacted at once. Not even a fraction of a second intervened. His gun flashed up, just as a small-game shooter hurls his weapon when a mallard glints above the decoys, and a little, angry cylinder of flame darted, as a snake's head darts, from the muzzle.

Hildreth didn't take aim. There wasn't time. The report roared in the darkness; the bullet sang harmlessly and thudded into the earth; and both of them were the last things in the world that Cranston had expected. And they were not a moment too soon. Even at that instant, his finger was closing down upon the trigger, Hildreth standing clear and revealed through the sights. The nervous response that few men in the world would be self-disciplined enough to prevent occurred at the same instant that he pressed the trigger. His own fire answered, so near to the other that both of them sounded as one report.
