But his chance did not come. He could not make friends with her, and at last, in despair of finding a better opportunity, he had slipped into her room one night in the small hours to steal the chain. But it was wound round her neck in such a way that he could not slip it over her head. She had awakened while he was fumbling with the clasp and had begun to cry. Hearing her mother moving about in the next room, he had hastily carried the child with him, mounted the horse waiting in the yard, and ridden away.
In the road he became aware, some time later, that he was being pursued. This gave him a dreadful fright, for, as Bucky had surmised, he thought his pursuer was Mackenzie. All night he rode southward wildly, but still his follower kept on his trail till near morning, when he eluded him. He crossed the border, but late that afternoon got another fright. For it was plain he was still being followed. In the endless stretch of rolling hills he twice caught sight of a rider picking his way toward him. The heart of the guilty man was like water. He could not face the outraged father, nor was it possible to escape so dogged a foe by flight. An alternative suggested itself, and he accepted it with sinking courage. The child was asleep in his arms now, and he hastily dismounted, picketed his horse, and stole back a quarter of a mile, so that the neighing of his bronco might not betray his presence. Then he lay down in a dense mesquit thicket and waited for his foe. It seemed an eternity till the man appeared at the top of a rise fifty yards away. Hastily Anderson fired, and again. The man toppled from his horse, dead before he struck the ground. But when the cook reached him he was horrified to see that the man he had killed was a member of the Rurales, or Mexican border police. In his guilty terror he had shot the wrong man.
He fled at once, pursued by a thousand fears. Late the next night he reached a Chihuahua village, after having been lost for many hours. The child he still carried with him, simply because he had not the heart to leave it to die in the desert alone. A few weeks later he married an American woman he met in Sonora. They adopted the child, but it died within the year of fever.
Meanwhile, he was horrified to learn that Dave Henderson, following hard on his trail, had been found bending over the spot where the dead soldier lay, had been arrested by a body of Rurales, tried hurriedly, and convicted to life imprisonment. The evidence had been purely circumstantial. The bullet found in the dead body of the trooper was one that might have come from his rifle, the barrel of which was empty and had been recently fired. For the rest, he was a hated Americano, and, as a matter of course, guilty. His judges took pains to see that no message from him reached his friends in the States before he was buried alive in the prison. In that horrible hole an innocent man had been confined for fifteen years, unless he had died during that time.
That, in substance, was the story told by the showman, and Bucky’s incisive questions were unable to shake any portion of it. As to the missing locket, the man explained that it had been broken off by accident and lost. When he discovered that only half the secret was contained on the map section he had returned the paper to the locket and let the child continue to carry it. Some years after the death of the child, Frances, his wife had lost the locket with the map.
“And this chain and locket—when did you lose them?” demanded Bucky sharply.
“It must have been about two months ago, down at Nogales, that I sold it to a fellow. I was playing faro and losing. He gave me five dollars for it.”
And to that he stuck stoutly, nor could he be shaken from it. Both O’Connor and the sheriff believed he was lying, for they were convinced that he was the bandit with the red wig who had covered the engineer while his companions robbed the train. But of this they had no proof. Nor did Bucky even mention his suspicion to Hardman, for it was his intention to turn him loose and have him watched. Thus, perhaps, he would be caught corresponding or fraternizing with some of the other outlaws. Collins left the room before the showman, and when the latter came from the hotel he followed him into the night.
Meanwhile, Bucky went out and tapped another of his underground wires. This ran directly to the Mexican consul at Tucson, to whom Bucky had once done a favor of some importance, and from him to Sonora and Chihuahua. It led to musty old official files, to records already yellowed with age, to court reports and prison registers. In the end it flashed back to Bucky great news. Dave Henderson, arrested for the murder of the Rurales policeman, was still serving time in a Mexican prison for another man’s crime. There in Chihuahua for fifteen years he had been lost to the world in that underground hole, blotted out from life so effectually that few now remembered there had been such a person. It was horrible, unthinkable, but none the less true.
