This book is a collection of 175 fundamental quotes and aphorisms of Arthur Conan Doyle:"Excellent!" I cried. "Elementary," said he.""Eliminate all other factors, and the one which remains must be the truth.""It is more than possible; it is probable.""Data! Data! Data!" he cried impatiently. "I can't make bricks without clay.""Any truth is better than indefinite doubt.""Evil indeed is the man who has not one woman to mourn him.""Anything is better than stagnation.""You see, but you do not observe. The distinction is clear.""Crime is common. Logic is rare. Therefore it is upon the logic rather than upon the crime that you should dwell."
