Sherlock Holmes - Sayings

“There can be no question, my dear Watson, of the value of exercise before breakfast.”
“My good Hopkins, I have investigated many crimes, but I have never yet seen one which was committed by a flying creature. As long as the criminal remains upon two legs so long must there be some indentation, some abrasion, some trifling displacement which can be detected by the scientific searcher.”

“One should always look for a possible alternative, and provide against it. It is the first rule of criminal investigation.”

“We all learn by experience, and your lesson this time is that you should never lose sight of the alternative.”
