‘Why don’t you help him?’ cried Ursula sharply.

He came again, and Birkin leaned to help him in to the boat. Gudrun again watched Gerald climb out of the water, but this time slowly, heavily, with the blind clambering motions of an amphibious beast, clumsy. Again the moon shone with faint luminosity on his white wet figure, on the stooping back and the rounded loins. But it looked defeated now, his body, it clambered and fell with slow clumsiness. He was breathing hoarsely too, like an animal that is suffering. He sat slack and motionless in the boat, his head blunt and blind like a seal’s, his whole appearance inhuman, unknowing. Gudrun shuddered as she mechanically followed his boat. Birkin rowed without speaking to the landing–stage.

‘Where are you going?’ Gerald asked suddenly, as if just waking up.

‘Home,’ said Birkin.

‘Oh no!’ said Gerald imperiously. ‘We can’t go home while they’re in the water. Turn back again, I’m going to find them.’ The women were frightened, his voice was so imperative and dangerous, almost mad, not to be opposed.

‘No!’ said Birkin. ‘You can’t.’ There was a strange fluid compulsion in his voice. Gerald was silent in a battle of wills. It was as if if he would kill the other man. But Birkin rowed evenly and unswerving, with an inhuman inevitability.

‘Why should you interfere?’ said Gerald, in hate.

Birkin did not answer. He rowed towards the land. And Gerald sat mute, like a dumb beast, panting, his teeth chattering, his arms inert, his head like a seal’s head.

They came to the landing–stage. Wet and naked–looking, Gerald climbed up the few steps. There stood his father, in the night.

‘Father!’ he said.

‘Yes my boy? Go home and get those things off.’

‘We shan’t save them, father,’ said Gerald.

‘There’s hope yet, my boy.’

‘I’m afraid not. There’s no knowing where they are. You can’t find them. And there’s a current, as cold as hell.’

‘We’ll let the water out,’ said the father. ‘Go home you and look to yourself. See that he’s looked after, Rupert,’ he added in a neutral voice.

‘Well father, I’m sorry. I’m sorry. I’m afraid it’s my fault. But it can’t be helped; I’ve done what I could for the moment. I could go on diving, of course—not much, though—and not much use—’

He moved away barefoot, on the planks of the platform. Then he trod on something sharp.

‘Of course, you’ve got no shoes on,’ said Birkin.

‘His shoes are here!’ cried Gudrun from below. She was making fast her boat.

Gerald waited for them to be brought to him. Gudrun came with them. He pulled them on his feet.

‘If you once die,’ he said, ‘then when it’s over, it’s finished. Why come to life again? There’s room under that water there for thousands.’

“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.”
