He had run off, single-handed, the road-agents who had held up the coach, and therefore became a hero at once, adding to his fame very quickly by showing that he could "shoot to kill" when attacked.
Signifying his intention of practising medicine and surgery in Last Chance, and gambling in his leisure moments, Doctor Dick had established himself in a pleasant cabin near the hotel, to at once become popular, and began to make money.
When Buffalo Bill went to Last Chance on a special secret-service mission, to investigate the holding up of the coach, and had recognized there a deserter, whom he had orders to take "dead or alive," Doctor Dick had helped him out of what appeared to be a very ugly scrape, and thus the two men had become friends.
Becoming confidential, Doctor Dick had told the scout a few chapters of his life, and he alone doubted that his foe from boyhood, Sergeant Wallace Weston—who had been reported as dying in the desert while seeking to escape—was dead, and the two, the scout and the gambler-doctor, had arranged to meet at the deserted camp and discover if the real truth could not be ascertained.
So it was at the deserted camp they had met, and Doctor Dick had stood with uncovered head before a quaking aspen-tree, at the foot of which was a grave.
Upon the tree had been cut a name and date, and this told that there lay the form of Hugh Mayhew, killed in a duel by one whom he had wronged.
It further told that Hugh Mayhew was known in the mines as a desperado, whose cruel deeds had gained for him the sobriquet of Black-heart Bill.
Convinced that the body in the grave was that of Hugh Mayhew, after he had unearthed the remains, and recognized in that decaying form his once brother—one of the triplets—Doctor Dick had seemed deeply moved when he told that he was the last of the trio and lived to avenge them: that he was sure Wallace Weston, their old foe, was their slayer, for he knew from the scout that he had killed his brother Manton at the fort, and hence he would not be convinced that the grave in the desert of Arizona held the body of Weston until he had certain proof of it.
"That man who came to your rescue, who called himself the Hermit of the Grand Cañon, who sought to shun you after his service to you, is either Wallace Weston, or knows something of him, and it is his trail we must pick up on his return to his retreat, and follow to the end, before I am satisfied," Doctor Dick had said to Buffalo Bill.
And so it was that the two had met at the deserted camp to pick up the trail of the hermit and follow it to the end, bring what it might to Doctor Dick.
