I called on my friend, Mr. Sherlock Holmes, one day in the autumn of last year and found him speaking to an elderly gentleman with fiery red hair.
“You could not have come at a better time,  my dear Watson,” Holmes said.
“I was afraid that you were engaged.”
“So I am.”
“Then I can wait in the next room.”
“Not at all. This gentleman, Mr. Wilson, has been my partner and helper in many of my most successful cases, and I have no doubt that he will be of use to me in yours also.”
The gentleman half rose from his chair and nodded.
“I know, my dear Watson, that you share my love of all that is outside the routine of everyday life. You have shown it by the enthusiasm with which you chronicled so many of my adventures,” said Holmes.
“Your cases have been of the greatest interest to me,” I observed.
“Now, Mr. Jabez Wilson here has been good enough to call upon me this morning and go begin a story which promises to be one of the most unusual which I have listened to for some time. As far as I have heard, it is impossible for me to say whether this case is an example of crime or not, but events are certainly very unusual. Perhaps, Mr. Wilson, you would repeat your story. I ask you not only because my friend, Dr. Watson, has not heard the beginning but also because your story makes me anxious to hear every detail. As a rule, when I have heard some story, I am able to think of the thousands of other similar cases. But not now.”
