Arthur Conan Doyle

“ These infernal Scowrers, this cursed vindictive nest of criminals—"
"No, no, my good sir," said Holmes. "There is a master hand here. It is no case of sawed-off shotguns and clumsy six-shooters. You can tell an old master by the sweep of his brush. I can tell a Moriarty when I see one. This crime is from London, not from America."
"But for what motive?"
"Because it is done by a man who cannot afford to fail, one whose whole unique position depends upon the fact that all he does must succeed. A great brain and a huge organization have been turned to the extinction of one man. ”

“ It is crushing the nut with the triphammer—an absurd extravagance of energy—but the nut is very effectually crushed all the same."
"How came this man to have anything to do with it?"
"I can only say that the first word that ever came to us of the business was from one of his lieutenants. These Americans were well advised. Having an English job to do, they took into partnership, as any foreign criminal could do, this great consultant in crime. From that moment their man was doomed. At first he would content himself by using his machinery in order to find their victim. ”
