overlooked?"

"I am afraid, my dear Watson, that most of your conclusions were
erroneous. When I said that you stimulated me I meant, to be
frank, that in noting your fallacies I was occasionally guided
towards the truth. Not that you are entirely wrong in this
instance. The man is certainly a country practitioner. And he
walks a good deal."

"Then I was right."

"To that extent."

"But that was all."

"No, no, my dear Watson, not all--by no means all. I would
suggest, for example, that a presentation to a doctor is more
likely to come from a hospital than from a hunt, and that when
the initials 'C.C.' are placed before that hospital the words
'Charing Cross' very naturally suggest themselves."

"You may be right."

"The probability lies in that direction. And if we take this as
a working hypothesis we have a fresh basis from which to start
our construction of this unknown visitor."

"Well, then, supposing that 'C.C.H.' does stand for 'Charing Cross
Hospital,' what further inferences may we draw?"
