Sir Arthur Conan Doyle: Memoirs of Sherlock Holmes

6. Adventure VI: The Reigate Puzzle (continued)

Sherlock Holmes was as good as his word, for about one o'clock he rejoined us in the Colonel's smoking-room. He was accompanied by a little elderly gentleman, who was introduced to me as the Mr. Acton whose house had been the scene of the original burglary.

"I wished Mr. Acton to be present while I demonstrated this small matter to you," said Holmes, "for it is natural that he should take a keen interest in the details. I am afraid, my dear Colonel, that you must regret the hour that you took in such a stormy petrel as I am."

"On the contrary," answered the Colonel, warmly, "I consider it the greatest privilege to have been permitted to study your methods of working. I confess that they quite surpass my expectations, and that I am utterly unable to account for you result. I have not yet seen the vestige of a clue."

"I am afraid that my explanation may disillusion you but it has always been my habit to hide none of my methods, either from my friend Watson or from any one who might take an intelligent interest in them. But, first, as I am rather shaken by the knocking about which I had in the dressing-room, I think that I shall help myself to a dash of your brandy, Colonel. My strength had been rather tried of late."

"I trust that you had no more of those nervous attacks."

Sherlock Holmes laughed heartily. "We will come to that in its turn," said he. "I will lay an account of the case before you in its due order, showing you the various points which guided me in my decision. Pray interrupt me if there is any inference which is not perfectly clear to you.

"It is of the highest importance in the art of detection to be able to recognize, out of a number of facts, which are incidental and which vital. Otherwise your energy and attention must be dissipated instead of being concentrated. Now, in this case there was not the slightest doubt in my mind from the first that the key of the whole matter must be looked for in the scrap of paper in the dead man's hand.
