Цитаты из книги A Study in Scarlet

"Видите ли, - объяснил Холмс, - по-моему, мозг человека похож на пустой чердачок, который вы обставляете по собственному желанию. Дурак тащит туда весь хлам, что попадет под руку, так что для нужных вещей не остаётся места или, в лучшем случае, их трудно найти в этой куче. А толковый профессионал очень тщательно отбирает то, что будет хранить на своем чердаке. Ему не нужно ничего, кроме того, что пригодится в работе, но такие вещи он запасает в большом разнообразии и содержит в идеальном порядке. Ошибется тот, кто подумает, будто стены у чердака эластичные и вместимость безграничная..."

Its invisibility, and the mystery which was attached to it, made this organization doubly terrible. It appeared to be omniscient and omnipotent, and yet was neither seen nor heard. The man who held out against the Church vanished away, and none knew whither he had gone or what had befallen him. His wife and his children awaited him at home, but no father ever returned to tell them how he had fared at the hands of his secret judges. A rash word or a hasty act was followed by annihilation, and yet none knew what the nature might be of this terrible power which was suspended over them. No wonder that men went about in fear and trembling, and that even in the heart of the wilderness they dared not whisper the doubts which oppressed them.

It is a mistake to confound strangeness with mystery. The most commonplace crime is often the most mysterious because it presents no new or special features from which deductions may be drawn. This murder would have been infinitely more difficult to unravel had the body of the victim been simply found lying in the roadway without any of those outré and sensational accompaniments which have rendered it remarkable. These strange details, far from making the case more difficult, have really had the effect of making it less so.
