‘Koln—Berlin—’ Ursula made out on the boards hung on the high train on one side.

‘Here we are,’ said Birkin. And on her side she saw: ‘Elsass—Lothringen—Luxembourg, Metz—Basle.’

‘That was it, Basle!’

The porter came up.

‘A Bale—deuxieme classe?—Voila!’ And he clambered into the high train. They followed. The compartments were already some of them taken. But many were dim and empty. The luggage was stowed, the porter was tipped.

‘Nous avons encore—?’ said Birkin, looking at his watch and at the porter.

‘Encore une demi–heure.’ With which, in his blue blouse, he disappeared. He was ugly and insolent.

‘Come,’ said Birkin. ‘It is cold. Let us eat.’

There was a coffee–wagon on the platform. They drank hot, watery coffee, and ate the long rolls, split, with ham between, which were such a wide bite that it almost dislocated Ursula’s jaw; and they walked beside the high trains. It was all so strange, so extremely desolate, like the underworld, grey, grey, dirt grey, desolate, forlorn, nowhere—grey, dreary nowhere.

At last they were moving through the night. In the darkness Ursula made out the flat fields, the wet flat dreary darkness of the Continent. They pulled up surprisingly soon—Bruges! Then on through the level darkness, with glimpses of sleeping farms and thin poplar trees and deserted high–roads. high She sat dismayed, hand in hand with Birkin. He pale, immobile like a REVENANT himself, looked sometimes out of the window, sometimes closed his eyes. Then his eyes opened again, dark as the darkness outside.

A flash of a few lights on the darkness—Ghent station! A few more spectres moving outside on the platform—then the bell—then motion again through the level darkness. Ursula saw a man with a lantern come out of a farm by the railway, and cross to the dark farm–buildings. She thought of the Marsh, the old, intimate farm–life at Cossethay. My God, how far was she projected from her childhood, how far was she still to go! In one life–time one travelled through aeons. The great chasm of memory from her childhood in the intimate country surroundings of Cossethay and the Marsh Farm—she remembered the servant Tilly, who used to give her bread and butter sprinkled with brown sugar, in the old living–room where the grandfather clock had two pink roses in a basket painted above the figures on the face—and now when she was travelling into the unknown with Birkin, an utter stranger—was so great, that it seemed she had no identity, that the child she had been, playing in Cossethay churchyard, was a little creature of history, not really herself.

They were at Brussels—half an hour for breakfast. They got down. On the great station clock it said six o’clock. They had coffee and rolls and honey in the vast desert refreshment room, so dreary, always so dreary, dirty, so spacious, such desolation of space. But she washed her face and hands in hot water, and combed her hair—that was a blessing.

“Mean? Why, it means that the writer was going to put the female name Rachel, but was disturbed before he or she had time to finish. You mark my words, when this case comes to be cleared up, you will find that a woman named Rachel has something to do with it. It’s all very well for you to laugh, Mr. Sherlock Holmes. You may be very smart and clever, but the old hound is the best, when all is said and done.”

“I really beg your pardon!” said my companion, who had ruffled the little man’s temper by bursting into an explosion of laughter. “You certainly have the credit of being the first of us to find this out and, as you say, it bears every mark of having been written by the other participant in last night’s mystery. I have not had time to examine this room yet, but with your permission I shall do so now.”

As he spoke, he whipped a tape measure and a large round magnifying glass from his pocket. With these two implements he trotted noiselessly about the room, sometimes stopping, occasionally kneeling, and once lying flat upon his face. So engrossed was he with his occupation that he appeared to have forgotten our presence, for he chattered away to himself under his breath the whole time, keeping up a running fire of exclamations, groans, whistles, and little cries suggestive of encouragement and of hope. As I watched him I was irresistibly reminded of a pure-blooded, well-trained foxhound, as it dashes backward and forward through the covert, whining in its eagerness, until it comes across the lost scent. For twenty minutes or more he continued his researches, measuring with the most exact care the distance between marks which were entirely invisible to me, and occasionally applying his tape to the walls in an equally incomprehensible manner. In one place he gathered up very carefully a little pile of gray dust from the floor, and packed it away in an envelope. Finally he examined with his glass the word upon the wall, going over every letter of it with the most minute exactness. This done, he appeared to be satisfied, for he replaced his tape and his glass in his pocket.

“They say that genius is an infinite capacity for taking pains,” he remarked with a smile. “It’s a very bad definition, but it does apply to detective work.”

Gregson and Lestrade had watched the manoeuvres of their amateur companion with considerable curiosity and some contempt. They evidently failed to appreciate the fact, which I had begun to realize, that Sherlock Holmes’s smallest actions were all directed towards some definite and practical end.

“What do you think of it, sir?” they both asked.

“It would be robbing you of the credit of the case if I were to presume to help you,” remarked my friend. “You are doing so well now that it would be a pity for anyone to interfere.” There was a world of sarcasm in his voice as he spoke. “If you will let me know how your investigations go,” he continued, “I shall be happy to give you any help I can. In the meantime I should like to speak to the constable who found the body. Can you give me his name and address?”
