A trusty comrade is always of use; and a chronicler still more so. 

Arthur Conan Doyle 

A client is to me a mere unit, a factor in a problem.

As a rule, said Holmes, the more bizarre a thing is the less mysterious it proves to be. It is your commonplace, featureless crimes which are really puzzling, just as a commonplace face is the most difficult to identify. 

Arthur Conan Doyle

Arthur Conan Doyle 

A man should keep his little brain attic stocked with all the furniture that he is likely to use, and the rest he can put away in the lumber-room of his library, where he can get it if he wants it. 

Arthur Conan Doyle 

Any truth is better than indefinite doubt. 

Arthur Conan Doyle

Arthur Conan Doyle

Arthur Conan Doyle
