A Real-Life Sherlock Holmes

Sir Arthur Conan Doyle, creator of the fictional detective
Sherlock Holmes, told of a time when he climbed into a taxi
cab in Paris. Before he could utter a word, the driver turned
to him and asked, “Where can I take you, Mr. Doyle?”
Doyle was flabbergasted. He asked the driver if he had ever
seen him before.
“No, sir,” the driver responded, “I have never seen you
before.”
Then he explained: “This morning’s paper had a story about
you being on vacation in Marseilles. This is the taxi stand
where people who return from Marseilles always come to.
Your skin color tells me you have been on vacation. The ink
spot on your right index finger suggests to me that you are
a writer. Your clothing is very English, and not French.
Adding up all those pieces of information, I deduced that
you are Sir Arthur Conan Doyle.”
“This is truly amazing!” the writer exclaimed. “You are a real
life counter-part to my fictional creation, Sherlock Holmes!”
“There is one other thing,” the driver said.
“What is that?”
“Your name is on the front of your suitcase.”
