Sequel to the last one
"Alright, Watson, I give up. How on earth did you know that I had taken that case?"
"Deduce it, my dear fellow."
"Watson, this is getting silly."
"Oh, alright. I applied your methods."
"That much was obvious from the beginning; there was no other way of doing it. Where did I slip? I was so sure that I did not show anything."
"You have an egotistical belief in your abilities, don't you? How do you know that there was no other way to do it?"
"Because I am Sherlock Holmes and it is my job to know what others don't. Now tell me, Watson."
"There were several slips you made. Five, to be accurate."
(sarcastically) "Do tell me."
"I'll tell the first four. Your boots, the way you talked, the state of your coat and your eyes."
"I do not see how any of these could have helped you; my boots are perfectly clean, I talked no differently to you today, I never even wore my coat today and my…eyes?"
"The last one was the clincher."
"And it is?"
"The telegram that you handed to me this morning to be sent to the telegram office which stated "Have accepted Jocelyn Case. Do not make any rash moves."
"The telegram-? Wait, are you telling me I gave you the telegram?!"
"Yes. Handed it and told me to send it."
"Oh."
"Getting on in years aren't you, Holmes?"
This is a double drabble.
