Sherlock Holmes clapped his hands softly together and chuckled.

“’Pon my word, Watson, you are coming along wonderfully. You have really done very well indeed. It is true that you have missed everything of importance, but you have hit upon the method, and you have a quick eye for colour. Never trust to general impressions, my boy, but concentrate yourself upon details. My first glance is always at a woman’s sleeve. In a man it is perhaps better first to take the knee of the trouser. As you observe, this woman had plush upon her sleeves, which is a most useful material for showing traces. The double line a little above the wrist, where the typewritist presses against the table, was beautifully defined. The sewing-machine, of the hand type, leaves a similar mark, but only on the left arm, and on the side of it farthest from the thumb, instead of being right across the broadest part, as this was. I then glanced at her face, and, observing the dint of a pince-nez at either side of her nose, I ventured a remark upon short sight and typewriting, which seemed to surprise her.”

“It surprised me.”

“But, surely, it was obvious. I was then much surprised and interested on glancing down to observe that, though the boots which she was wearing were not unlike each other, they were really odd ones; the one having a a slightly decorated toe-cap, and the other a plain one. One was buttoned only in the two lower buttons out of five, and the other at the first, third, and fifth. Now, when you see that a young lady, otherwise neatly dressed, has come away from home with odd boots, half-buttoned, it is no great deduction to say that she came away in a hurry.”

“And what else?” I asked, keenly interested, as I always was, by my friend’s incisive reasoning.

“I noted, in passing, that she had written a note before leaving home but after being fully dressed. You observed that her right glove was torn at the forefinger, but you did not apparently see that both glove and finger were stained with violet ink. She had written in a hurry and dipped her pen too deep. It must have been this morning, or the mark would not remain clear upon the finger. All this is amusing, though rather elementary, but I must go back to business, Watson. Would you mind reading me the advertised description of Mr. Hosmer Angel?”

I held the little printed slip to the light.

“Missing [it said] on the morning of the fourteenth, a gentleman named Hosmer Angel. About five feet seven inches in height; strongly built, sallow complexion, black hair, a little bald in the centre, bushy, black side-whiskers and moustache; tinted glasses, slight infirmity of speech. Was dressed, when last seen, in black frock-coat faced with silk, black waistcoat, gold Albert chain, and gray Harris tweed trousers, with brown gaiters over elastic-sided boots. Known to have been employed in an office in Leadenhall Street. Anybody bringing —”

“That will do,” said Holmes. “As to the letters,” he continued, glancing over them, “they are very commonplace. Absolutely no clue in them to Mr. Angel, save that he quotes Balzac once. There is one remarkable point, however, which will no doubt strike you.”

Aaron, the dream–Aaron, turned another way, and strayed along the vast square rooms, cavern apartments. He came into one room where there were many children, all in white gowns. And they were all busily putting themselves to bed, in the many beds scattered about the room at haphazard. And each child went to bed with a wreath of flowers on its head, white flowers and pink, so it seemed. So there they all lay, in their flower–crowns in the vast space of the rooms. And Aaron went away.

He could not remember the following part. Only he seemed to have passed through many grey domestic apartments, where were all women, all greyish in their clothes and appearance, being wives of the underground tin–miners. The men were away and the dream–Aaron remembered with fear the food they were to eat.

The next thing he could recall was, that he was in a boat. And now he was most definitely two people. His invisible, conscious self, what we have called his second self, hovered as it were before the prow of the boat, seeing and knowing, but unseen. His other self, the palpable Aaron, sat as a passenger in the boat, which was being rowed by the unknown people of this underworld. They stood up as they thrust the boat along. Other passengers were in the boat too, women as well, but all of them unknown people, and not noticeable.

The boat was upon a great lake in the underworld country, a lake of dark blue water, but crystal clear and very beautiful in colour. The second or invisible Aaron sat in the prow and watched the fishes swimming suspended in the clear, beautiful dark–blue water. Some were pale fish, some frightening–looking, like centipedes swimming, and some were dark fish, of definite form, and delightful to watch.

The palpable or visible Aaron sat at the side of the boat, on the end of the middle seat, with his naked right elbow leaning out over the side. And now the boat entered upon shallows. The impalpable Aaron in the bows saw the whitish clay of the bottom swirl up in clouds at each thrust of the oars, whitish–clayey clouds which would envelope the strange fishes in a sudden mist. And on the right hand of the course stakes stood up in the water, at intervals, to mark the course.

The boat must pass very near these stakes, almost touching. And Aaron’s naked elbow was leaning right over the side. As they approached the first stake, the boatmen all uttered a strange cry of warning, in a foreign language. The flesh–and–blood Aaron seemed not even to hear. The invisible Aaron heard, but did not comprehend the words of the cry.

So the naked elbow struck smartly against the stake as the boat passed.

The rowers rowed on. And still the flesh–and–blood Aaron sat with his arm over the side. Another stake was nearing. “Will he heed, will he heed?” thought the anxious second self. The rowers gave the strange warning cry. He did not heed, and again the elbow struck against the stake as the boat passed. And yet the flesh–and–blood Aaron sat on and made no sign. There were stakes all along this shallow part of the lake. Beyond was deep water again. The invisible Aaron was becoming anxious. “Will he never hear? Will he never heed? Will he never understand?” he thought. And he watched in pain for the next stake. But still the flesh–and–blood Aaron sat on, and though the rowers cried so acutely that the invisible Aaron almost understood their very language, still the Aaron seated at the side heard nothing, and his elbow struck against the third stake.
