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.
