3. Watchman was down on one knee inspecting the hoof-prints when the whacking boom of an explosion froze him in alarm. Rifle shot; he recognized the sound a second later. Its hard echo beat across the hills. The report was directionless. Watchman crouched back against a ball of scrub oak. His head turned quickly, he tried to watch everything at once. There was no way of knowing whether that rifle was shooting at him or at something else but he could hardly ignore it. He unsnapped the holster and palmed his service revolver. The adrenaline pumping through him made his hand shake. The rifle boomed again and this time the bullet made a crease in the earth twenty feet to his right; it whined away like a flat stone skipped across a pond. He heard the nearby crack of the next one. It broke some twigs out of the scrub oak beside him. He threw himself belly-flat behind the scrub oak and fired two blind shots in the general direction he thought the rifle had spoken from. Instinct prompted panic but his experience steadied him. There were two possibilities. Either the rifleman was a terrible marksman or he hadnât meant to hit Watchman. Either way it meant he wasnât likely to get killed right here and right now.

That was two in a row the rifle had put into the oak; so the odds changed. Not a poor marksman; they were warning shots. Flat on the ground he considered his horizons. There was a dip behind him, twenty feet awayâa shallow crease in the land that had probably been a torrent two hours ago. He began to slide back toward the gully; he triggered three .38s toward the place where heâd seen the muzzle flame, rolled into the gully and slithered in the mud and a rifle bullet chopped the air overhead. Now what the hell? He was fumbling to reload. Two cartridges dropped from his hand and he left them in the mud. Youâve got no right to scare a man this way. He whacked the cylinder closed and fired a couple of potluck rounds. The revolver slammed against the heel of his hand in recoil; the racket had his ears ringing. The stink of cordite fouled the air. There was a shot but it wasnât aimed
