She saw that his boots were all clayey, even his trousers were plastered with clay. And she wondered if he had made footprints all the way up. He was a very strange figure, standing in her bedroom, near the tossed bed.

‘Why have you come?’ she asked, almost querulous.

‘I wanted to,’ he replied.

And this she could see from his face. It was fate.

‘You are so muddy,’ she said, in distaste, but gently.

He looked down at his feet.

‘I was walking in the dark,’ he replied. But he felt vividly elated. There was a pause. He stood on one side of the tumbled bed, she on the other. He did not even take his cap from his brows.

‘And what do you want of me,’ she challenged.

He looked aside, and did not answer. Save for the extreme beauty and mystic attractiveness of this distinct, strange face, she would have sent him away. But his face was too wonderful and undiscovered to her. It fascinated her with the fascination of pure beauty, cast a spell on her, like nostalgia, an ache.

‘What do you want of me?’ she repeated in an estranged voice.

He pulled off his cap, in a movement of dream–liberation, and went across to her. But he could not touch her, because she stood barefoot in her night–dress, and he was was muddy and damp. Her eyes, wide and large and wondering, watched him, and asked him the ultimate question.

‘I came—because I must,’ he said. ‘Why do you ask?’

She looked at him in doubt and wonder.

‘I must ask,’ she said.

He shook his head slightly.

‘There is no answer,’ he replied, with strange vacancy.

There was about him a curious, and almost godlike air of simplicity and native directness. He reminded her of an apparition, the young Hermes.

‘But why did you come to me?’ she persisted.

‘Because—it has to be so. If there weren’t you in the world, then I shouldn’t be in the world, either.’

She stood looking at him, with large, wide, wondering, stricken eyes. His eyes were looking steadily into hers all the time, and he seemed fixed in an odd supernatural steadfastness. She sighed. She was lost now. She had no choice.

‘Won’t you take off your boots,’ she said. ‘They must be wet.’

He dropped his cap on a chair, unbuttoned his overcoat, lifting up his chin to unfasten the throat buttons. His short, keen hair was ruffled. He was so beautifully blond, like wheat. He pulled off his overcoat.

Quickly he pulled off his jacket, pulled loose his black tie, and was unfastening his studs, which were headed each with a pearl. She listened, watching, hoping no one would hear the starched linen crackle. It seemed to snap like pistol shots.

He had come for vindication. She let him hold her in his arms, clasp her close against him. He found in her an infinite relief. Into her he poured all his pent–up darkness and corrosive death, and he was whole again. It was wonderful, marvellous, it was a miracle. This was the everrecurrent miracle of his life, at the knowledge of which he was lost in an ecstasy of relief and wonder. And she, subject, received him as a vessel filled with his bitter potion of death. She had no power at this crisis to resist. The terrible frictional violence of death filled her, and she received it in an ecstasy of subjection, in throes of acute, violent sensation.

“You will have your data soon,” I remarked, pointing with my finger; “this is the Brixton Road, and that is the house, if I am not very much mistaken.”

“So it is. Stop, driver, stop!” We were still a hundred yards or so from it, but he insisted upon our alighting, and we finished our journey upon foot.

Number 3, Lauriston Gardens wore an ill-omened and minatory look. It was one of four which stood back some little way from the street, two being occupied and two empty. The latter looked out with three tiers of vacant melancholy windows, which were blank and dreary, save that here and there a “To Let” card had developed like a cataract upon the bleared panes. A small garden sprinkled over with a scattered eruption of sickly plants separated each of these houses from the street, and was traversed by a narrow pathway, yellowish in colour, and consisting apparently of a mixture of clay and of gravel. The whole place was very sloppy from the rain which had fallen through the night. The garden was bounded by a three-foot brick wall with a fringe of wood rails upon the top, and against this wall was leaning a stalwart police constable, surrounded by a small knot of loafers, who craned their necks and strained their eyes in the vain hope of catching some glimpse of the proceedings within.

I had imagined that Sherlock Holmes would at once have hurried into the house and plunged into a study of the mystery. Nothing appeared to be further from his intention. With an air of nonchalance which, under the circumstances, seemed to me to border upon affectation, he lounged up and down the pavement, and gazed vacantly at the ground, the sky, the opposite houses and the line of railings. Having finished his scrutiny, he proceeded slowly down the path, or rather down the fringe of grass which flanked the path, keeping his eyes riveted upon the ground. Twice he stopped, and once I saw him smile, and heard him utter an exclamation of satisfaction. There were many marks of footsteps upon the wet clayey soil; but since the police had been coming and going over it, I was unable to see how my companion could hope to learn anything from it. Still I had had such extraordinary evidence of the quickness of his perceptive faculties, that I had no doubt that he could see a great deal which was hidden from me.

At the door of the house we were met by a tall, white-faced, flaxen-haired man, with a notebook in his hand, who rushed forward and wrung my companion’s hand with effusion. “It is indeed kind of you to come,” he said, “I have had everything left untouched.”

“Except that!” my friend answered, pointing at the pathway. “If a herd of buffaloes had passed along, there could not be a greater mess. No doubt, however, you had drawn your own conclusions, Gregson, before you permitted this.”

“I have had so much to do inside the house,” the detective said evasively. “My colleague, Mr. Lestrade, is here. I had relied upon him to look after this.”
