To ride an unshod horse in the southern desert is to invite disaster.  Toward evening, Pete pulled up at a water-hole, straightened the nails in the horseshoes and tacked them on again with a piece of rock.  They would hold until he reached the desert town of Showdown—­a place of ill-repute and a rendezvous for outlawry and crime.

He rode on until he came within sight of the town—­a dim huddle of low buildings in the starlight.  He swung off the trail, hobbled his horse, fastened his rope to the hobbles, and tied that in turn to a long, heavy slab of rock, and turned in.  He would not risk losing his horse in this desert land.  At best a posse could not reach Showdown before noon the next day, and rather than blunder into Showdown at night and take unnecessary risks, he decided to rest, and ride in at sunup, when he would be able to see what he was doing and better estimate the possibilities of getting food for himself and his horse and of finding refuge in some out-of-the-way ranch or homestead.  In spite of his vivid imaginings he slept well.  At dawn he caught up his pony and rode into town.

Showdown boasted some fifteen or eighteen low-roofed adobes, the most pretentious being the saloon.  These all faced a straggling road which ran east and west, disappearing at either end of the town as though anxious to obliterate itself in the clean sand of the desert.  The environs of Showdown were garnished with tin cans and trash, dirt and desolation.  Unlike the ordinary cow-town this place was not sprightly, but morose, with an aspect of hating itself for existing.  Even the railroad swung many miles to the south as though anxious to leave the town to its own pernicious isolation.

The fixed population consisted of a few Mexicans and one white man, known as “The Spider,” who ran the saloon and consequently owned Showdown body and—­but Showdown had no soul.

Men arrived and departed along the several desert trails that led in and out of the town.  These men seldom tarried long.  And they usually came alone, perchance from the Blue, the Gila, the T-Bar-T, or from below the border, for their business was with the border rustlers and parasites.  Sheriffs of four counties seldom disturbed the place, because a man who had got as far south as Showdown was pretty hard to apprehend.  From there to the border lay a trackless desert.  Showdown was a rendezvous for that inglorious legion, “The Men Who Can’t Come Back,” renegades who when below the line worked machine guns for whichever side of the argument promised the more loot.  Horse- and cattle-thieves, killers, escaped convicts, came and went—­ominous birds of passage, the scavengers of war and banditry.

The Spider was lean, with legs warped by long years in the saddle.  He was called The Spider because of his physical attributes as well as because of his attitude toward life.  He never went anywhere, yet he accumulated sustenance.  He usually had a victim tangled in his web.  It was said that The Spider never let a wounded outlaw die for lack of proper attention if he considered the outlaw worth saving—­as an investment.  And possibly this was the secret of his power, for he was ever ready to grub-stake or doctor any gentleman in need or wounded in a desert affair—­and he had had a large experience in caring for gun-shot wounds.
