ABOUT CONAN DOYLE
There is probably no one among book-lovers who has not heard of Sherlock Holmes in
the stories by Arthur Conan Doyle. Sherlock Holmes's method of analyzing the most
difficult problems was to notice the smallest facts, even if they seemed unimportant.
His method never failed; the criminal always had to give up, and to become the
prisoner of the great detective.
Conan Doyle once arrived in Paris, after spending a month in the south of France.
There was a long row of cabs outside the gate of the railway station. Conan Doyle got
into the first cab and ordered the driver to take him to a good hotel. The driver was
silent all the way to the hotel, but when Conan Doyle paid him, he said, "Thank you,
Sir Arthur Conan Doyle".
"How do you know who I am?" Conan Doyle asked in the greatest surprise.
"I have never seen you before", the man answered, "so I can't pretend that I recognized
you. But I read in the newspapers that you were expected in Paris after your vacation
in the south of France. The train you arrived on came from the south of France. I could
tell from your clothes, especially your hat, and also from the strange way you
pronounce French words that you were English. These facts helped me to guess that
you were probably Sir Arthur Conan Doyle".
"Fine work! Wonderful!" Conan Doyle cried. "You analyzed the facts quite correctly.
It's a pity you aren't a detective!"
"Of course", the driver added, "your name is on both your travelling bags. I can't
pretend that fact didn't help".
