"Quite so (совершенно верно: «вполне так»). I have a kind of intuition that way (у меня что-то вроде интуиции в этом деле; way — область, сфера занятий). Now and again a case turns up which is a little more complex (время от времени подворачивается более сложный случай; to turn up — неожиданно появляться; случаться). Then I have to bustle about and see things with my own eyes (тогда мне приходится побегать и осмотреть все собственными глазами; to bustle about — хлопотать, суетиться). You see I have a lot of special knowledge which I apply to the problem (видите ли, у меня богатый запас специальных познаний, которые я применяю для решения проблемы; a lot of — много), and which facilitates matters wonderfully (что чудесно облегчает дело: «которые /знания/ содействуют делу замечательно»). Those rules of deduction laid down in that article which aroused your scorn (те правила дедукции, которые изложены в статье и вызвали вашу насмешку; to lay down — устанавливать, утверждать; to arouse — будить, пробуждать; scorn — презрение, пренебрежение; насмешка), are invaluable to me in practical work (неоценимы для меня в практической работе). Observation with me is second nature (наблюдательность — это моя вторая натура). You appeared to be surprised when I told you, on our first meeting (вы выглядели удивленным, когда я сказал вам при нашей первой встрече), that you had come from Afghanistan (что вы прибыли из Афганистана)."

"And these other people?"
"They are mostly sent on by private inquiry agencies. They are all people who are in trouble about something, and want a little enlightening. I listen to their story, they listen to my comments, and then I pocket my fee."
"But do you mean to say," I said, "that without leaving your room you can unravel some knot which other men can make nothing of, although they have seen every detail for themselves?"
