For a few moments she was borne away on the wild wings of ambition. Gerald, with his force of will and his power for comprehending the actual world, should be set to solve the problems of the day, the problem of industrialism in the modern world. She knew he would, in the course of time, effect the changes he desired, he could re–organise the industrial system. She knew he could do it. As an instrument, in these things, he was marvellous, she had never seen any man with his potentiality. He was unaware of it, but she knew.

He only needed to be hitched on, he needed that his hand should be set to the task, because he was so unconscious. And this she could do. She would marry him, he would go into Parliament in the Conservative interest, he would clear up the great muddle of labour and industry. He was so superbly fearless, masterful, he knew that every problem could be worked out, in life as in geometry. And he would care neither about himself nor about anything but the pure working out of the problem. He was very pure, really.

Her heart beat fast, she flew away on wings of elation, imagining a future. He would be a Napoleon of peace, or a Bismarck—and she the woman woman behind him. She had read Bismarck’s letters, and had been deeply moved by them. And Gerald would be freer, more dauntless than Bismarck.

But even as she lay in fictitious transport, bathed in the strange, false sunshine of hope in life, something seemed to snap in her, and a terrible cynicism began to gain upon her, blowing in like a wind. Everything turned to irony with her: the last flavour of everything was ironical. When she felt her pang of undeniable reality, this was when she knew the hard irony of hopes and ideas.

She lay and looked at him, as he slept. He was sheerly beautiful, he was a perfect instrument. To her mind, he was a pure, inhuman, almost superhuman instrument. His instrumentality appealed so strongly to her, she wished she were God, to use him as a tool.

And at the same instant, came the ironical question: ‘What for?’ She thought of the colliers’ wives, with their linoleum and their lace curtains and their little girls in high–laced boots. She thought of the wives and daughters of the pit–managers, their tennis–parties, and their terrible struggles to be superior each to the other, in the social scale. There was Shortlands with its meaningless distinction, the meaningless crowd of the Criches. There was London, the House of Commons, the extant social world. My God!

Young as she was, Gudrun had touched the whole pulse of social England. She had no ideas of rising in the world. She knew, with the perfect cynicism of cruel youth, that to rise in the world meant to have one outside show instead of another, the advance was like having a spurious half–crown instead of a spurious penny. The whole coinage of valuation was spurious. Yet of course, her cynicism knew well enough that, in a world where spurious coin was current, a bad sovereign was better than a bad farthing. But rich and poor, she despised both alike.

“You would lose your money,” Holmes remarked calmly. “As for the article, I wrote it myself.”

“You!”

“Yes; I have a turn both for observation and for deduction. The theories which I have expressed there, and which appear to you to be so chimerical, are really extremely practical — so practical that I depend upon them for my bread and cheese.”

“And how?” I asked involuntarily.

“Well, I have a trade of my own. I suppose I am the only one in the world. I’m a consulting detective, if you can understand what that is. Here in London we have lots of government detectives and lots of private ones. When these fellows are at fault, they come to me, and I manage to put them on the right scent. They lay all the evidence before me, and I am generally able, by the help of my knowledge of the history of crime, to set them straight. There is a strong family resemblance about misdeeds, and if you have all the details of a thousand at your finger ends, it is odd if you can’t unravel the thousand and first. Lestrade is a well-known detective. He got himself into a fog recently over a forgery case, and that was what brought him here.”

“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?”

“Quite so. I have a kind of intuition that way. Now and again a case turns up which is a little more complex. Then I have to bustle about and see things with my own eyes. You see I have a lot of special knowledge which I apply to the problem, and which facilitates matters wonderfully. Those rules of deduction laid down in that article which aroused your scorn are invaluable to me in practical work. Observation with me is second nature. You appeared to be surprised when I told you, on our first meeting, that you had come from Afghanistan.”

“You were told, no doubt.”

“Nothing of the sort. I knew you came from Afghanistan. From long habit the train of thoughts ran so swiftly through my mind that I arrived at the conclusion without being conscious of intermediate steps. There were such steps, however. The train of reasoning ran, ‘Here is a gentleman of a medical type, but with the air of a military man. Clearly an army doctor, then. He has just come from the tropics, for his face is dark, and that is not the natural tint of his skin, for his wrists are fair. He has undergone hardship and sickness, as his haggard face says clearly. His left arm has been injured. He holds it in a stiff and unnatural manner. Where in the tropics could an English army doctor have seen much hardship and got his arm wounded? Clearly in Afghanistan.’ The whole train of thought did not occupy a second. I then remarked that you came from Afghanistan, and you were astonished.”
