If Sheriff Pete Glass had been the typical hard-riding, sure-shooting officer of the law as it is seen in the mountain-desert, his work would have died with his death, but Glass had a mind as active as his hands, and therefore, for at least a little while, his work went on after him. He had gathered fifteen practiced fighters who represented, it might be said, the brute¹ body of the law, and when they, with most of Rickett at their heels, burst down the door of the Sheriff's office and found his body, they had only one thought, which was to swing into the saddle and ride on the trail of the killer², who was even now in a diminishing cloud of dust down the street. He was riding almost due east, and the cry went up: “He's streakin' it for the Morgan Hills. Git after him, boys!” So into the saddle they went with a rush, fifteen tried men on fifteen chosen horses, and went down the street with a roar of hoof-beats. That was the body and muscle of the sheriff's work going out to avenge⁴ him, but the mind of the law remained behind.  
It was old Billy, the clerk. No one paid particular attention to Billy, and they never had. He was useless on a horse and ridiculous with a gun, and the only place where he seemed formidable was behind a typewriter. Now he sat looking, down into the dead face of Pete Glass, trying to grasp the meaning of it all. From the first he had been with Pete, from the first the invincibility⁵ of the little dusty man had been the chief article of Billy's creed⁶, and now his dull eyes, bleared with thirty years of clerical labor⁷, wandered around on the galaxy⁸ of dead men who looked down at him from the wall. He leaned over and took the hand of the sheriff as one would lean to help up a fallen man, but the fingers were already growing cold, and then Billy realized for the first time that this was death. Pete Glass had been; Pete Glass was not.
 
Next he knew that something had to be done, but what it was he could not tell, for he sat in the sheriff's office and in that room he was accustomed to stop thinking and receive orders. He went back to his own little cubby-hole, and sat down behind the typewriter; at once his mind cleared, thoughts came, and linked themselves into ideas, pictures, plans.
 
The murderer must be taken, dead or alive, and those fifteen men had ridden out to do the necessary thing. They had seemed irresistible¹⁰, as they departed; indeed, no living thing they met could withstand them, human or otherwise, as Billy very well knew. Yet he recalled a saying of the sheriff, a thing he had insisted upon: “No man on no hoss will ever ride down Whistlin' Dan Barry. It's been tried before and it's never worked. I've looked up his history and it can't be done. If he's goin' to be ran down it's got to be done with relays, like you was runnin' down a wild hoss.” Billy rubbed his bald head and thought and thought.
 
With that orderliness which had become his habit of mind, from work with reports and papers, sorting and filing away, Billy went back to the beginning. Dan Barry was fleeing. He started from Rickett, and nine chances out of ten he was heading, eventually, towards those practically impenetrable mountain ranges where the sheriff before had lost the trail after the escape from the cabin and the killing¹¹ of Mat Henshaw. Towards this same region, again, he had retreated after the notorious Killing at Alder¹². There was no doubt, then, humanly speaking, that he would make for the same safe refuge.
 
At first glance this seemed quite improbable, to be sure, for the Morgan Hills lay due east, or very nearly east, while the place from which Barry must have sallied forth¹³ and to which he would return was somewhere well north of west, and a good forty miles away. It seemed strange that he should strike off in the opposite direction, so Billy closed his eyes, leaned back in his chair, and summoned up a picture of the country.
 
Five miles to the east the Morgan Hills rolled, sharply broken ups and downs of country—bad lands rather than real hills, and a difficult region to keep game in view. That very idea gave Billy his clue. Barry knew that he would be followed hard and fast, and he headed straight for the Morgan's to throw the posse off the final direction he intended to take in his flight. In spite of the matchless speed of that black stallion of which the sheriff had learned so much, he would probably let the posse keep within easy view of him until he was deep within the bad-lands. Then he would double, sharply around and strike out in the true direction of his flight.
 
Having reached this point in his deductions¹⁴, Billy smote¹⁵ his hands together. He was trembling with excitement so that he filled his pipe with difficulty. By the time it was drawing well he was back examining his mental picture of the country.
 
West of Rickett about the same distance as Morgan Hills, ran the Wago Mountains, low, rolling ranges which would hardly form an impediment for a horseman. Across these Barry might cut at a good speed on his western course, but some fifteen or twenty miles from Rickett he was bound to reach a most difficult barrier. It was the Asper river, at this season of the year swollen¹⁶ high and swift with snow-water—a rare feat¹⁷ indeed if a man could swim his horse across such a stream. There were only two places in which it could be forded.
 
About fifty miles north and a little east of the line from Rickett the Asper spread out into a broad, shallow bed, its streams dispersed¹⁹ for several miles into a number of channels which united again, farther down the course, and made the same strong river. Towards this ford¹⁸, therefore, it was possible that Dan Barry would head, in the region of Caswell City.
 
There was, however, another way of crossing the stream. Almost due west of Rickett, a distance of fifteen miles, Tucker Creek²⁰ joined the Asper. Above the point of junction²¹ both the creek and the river were readily fordable, and Barry could cross them and head straight for his goal.
 
It was true that to make Tucker Creek he would have to double out of the Morgan Hills and brush back perilously²² close to Rickett, but Billy was convinced that this was the outlaw²³'s plan; for though the Caswell City fords would be his safest route it would take him a day's ride, on an ordinary horse, out of his way. Besides, the sheriff had always said: “Barry will play the chance!”
 
Billy would have ventured his life that the fugitive²⁴ would strike straight for the Creek as soon as he doubled out of Morgan Hills.
 
Doors began to bang; a hundred pairs of boots thudded and jingled²⁵ towards Billy; the noise of voices rolled through the outer hall, poured through the ............
