Despite this bizarre behavior, or perhaps because of it, his consulting services were enormously popular. No doubt a contributing reason was that he charged no fee for his diagnoses. It was no coincidence, however, that Budd prescribed medicine for every patient. Their pills could be conveniently purchased down the hall, where Mrs. Budd typed up the labels for the bottles and took the patients’ money. Budd earned a fortune from this dubious practice. He made a point each day on his way to the bank to carry his earnings in a big bag through the doctors’ quarter of the city, jingling it as he went, just to rankle his fellow practitioners. He was convinced that the rules of medical ethics were a con game to keep young, energetic doctors subservient to their elders.

Conan Doyle was both appalled and amused by this display. When Budd offered to help him start a practice of his own, however, he accepted. Budd furnished Conan Doyle with a consulting room in his clinic, then flooded him with advice on how to run his life. One suggestion was to start a novel that very day. Although he had already published one short story, Conan Doyle hadn’t considered writing anything as ambitious as a novel. But because he had no patients as yet and thus plenty of time on his hands, he gave it a try.

There is no evidence that Sherlock Holmes was born out of this circumstance, or that Budd contributed anything more to the character than his energy, range of interests, and black moods. But he contributed something else essential that runs throughout Doyle’s work. Through Budd, Conan Doyle experienced deception and betrayal for the first time. Of course Conan Doyle knew, as we all do, that people can lie and turn against former friends, but it makes a different and certainly deeper impression when it happens to you personally. It came about in the following way.

During his time in Budd’s clinic, Conan Doyle’s mother wrote him letters expressing her displeasure at his involvement with Budd, whom she considered an unscrupulous character. Budd apparently sneaked the letters out of Conan Doyle’s room, read them without Conan Doyle’s knowledge, and developed a bitter resentment against his friend. At some point he complained that his own practice was dwindling because of Conan Doyle. As Conan Doyle, unlike Budd, really was a man of honor, he immediately went to his office door with a hammer and pulled off his nameplate.

This display of character softened Budd’s resentment, at least for a while. He proposed to lend Conan Doyle a pound a week to help him set up a practice in Portsmouth. Once Conan Doyle moved to that city to restart his medical career, Budd reneged on the payment. He wrote to Conan Doyle, quoting what he considered slanderous passages from a letter of Conan Doyle’s mother, which he claimed the maid had found torn in pieces under the grate. This kind of back-stabbing carried on under his roof was a betrayal he couldn’t forgive, said Budd. He would have nothing more to do with Conan Doyle.

Conan Doyle was stunned. Upon thinking it over, he couldn’t remember ever tearing up any of his letters. Searching through his pockets he found the very one from which Budd had quoted. He realized Budd’s lie about finding the letter meant Budd was lying and must have been reading his mail surreptitiously. He wrote back to say he had seen through the clumsy plot, thanking Budd for removing the only disagreement between himself and his mother by confirming her low opinion of Budd. He assured Budd that any attempt to harm him had backfired.

The incident left a haunting memory.
