Rosalind opened the door to him. She started slightly, as a young girl will, and said:

‘Oh, I’ll tell father.’

With which she disappeared, leaving Birkin in the hall, looking at some reproductions from Picasso, lately introduced by Gudrun. He was admiring the almost wizard, sensuous apprehension of the earth, when Will Brangwen appeared, rolling down his shirt sleeves.

‘Well,’ said Brangwen, ‘I’ll get a coat.’ And he too disappeared for a moment. Then he returned, and opened the door of the drawing–room, saying:

‘You must excuse me, I was just doing a bit of work in the shed. Come inside, will you.’

Birkin entered and sat down. He looked at the bright, reddish face of the other man, at the narrow brow and the very bright eyes, and at the rather sensual lips that unrolled wide and expansive under the black cropped moustache. How curious it was that this was a human being! What Brangwen thought himself to be, how meaningless it was, confronted with the reality of him. Birkin could see only a strange, inexplicable, almost patternless collection of passions and desires and suppressions and traditions and mechanical ideas, all cast unfused and disunited into this slender, bright–faced man of nearly fifty, who was as unresolved now as as he was at twenty, and as uncreated. How could he be the parent of Ursula, when he was not created himself. He was not a parent. A slip of living flesh had been transmitted through him, but the spirit had not come from him. The spirit had not come from any ancestor, it had come out of the unknown. A child is the child of the mystery, or it is uncreated.

‘The weather’s not so bad as it has been,’ said Brangwen, after waiting a moment. There was no connection between the two men.

‘No,’ said Birkin. ‘It was full moon two days ago.’

‘Oh! You believe in the moon then, affecting the weather?’

‘No, I don’t think I do. I don’t really know enough about it.’

‘You know what they say? The moon and the weather may change together, but the change of the moon won’t change the weather.’

‘Is that it?’ said Birkin. ‘I hadn’t heard it.’

There was a pause. Then Birkin said:

‘Am I hindering you? I called to see Ursula, really. Is she at home?’

‘I don’t believe she is. I believe she’s gone to the library. I’ll just see.’

Birkin could hear him enquiring in the dining–room.

‘No,’ he said, coming back. ‘But she won’t be long. You wanted to speak to her?’

Birkin looked across at the other man with curious calm, clear eyes.

‘As a matter of fact,’ he said, ‘I wanted to ask her to marry me.’

A point of light came on the golden–brown eyes of the elder man.

‘O–oh?’ he said, looking at Birkin, then dropping his eyes before the calm, steadily watching look of the other: ‘Was she expecting you then?’

“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.”
