"There was something very peculiar about Doc. He was gentlemanly, a good dentist, a friendly man and yet, outside of us boys, I don't think he had a friend in the Territory.  Tales were told that he had murdered men in different parts of the country;  that he had robbed and committed all manner of crimes, and yet, when persons were asked how they knew it, they could only admit it was hearsay, and that nothing of the kind could really be traced to Doc's account.  He was a slender, sickly fellow, but whenever a stage was robbed or a row started, and help was needed, Doc was one of the first to saddle his horse and report for duty."
