For a few moments she was borne away on the wild wings of ambition. Gerald, with his force of will and his power for comprehending the actual world, should be set to solve the problems of the day, the problem of industrialism in the modern world. She knew he would, in the course of time, effect the changes he desired, he could re–organise the industrial system. She knew he could do it. As an instrument, in these things, he was marvellous, she had never seen any man with his potentiality. He was unaware of it, but she knew.

He only needed to be hitched on, he needed that his hand should be set to the task, because he was so unconscious. And this she could do. She would marry him, he would go into Parliament in the Conservative interest, he would clear up the great muddle of labour and industry. He was so superbly fearless, masterful, he knew that every problem could be worked out, in life as in geometry. And he would care neither about himself nor about anything but the pure working out of the problem. He was very pure, really.

Her heart beat fast, she flew away on wings of elation, imagining a future. He would be a Napoleon of peace, or a Bismarck—and she the woman woman behind him. She had read Bismarck’s letters, and had been deeply moved by them. And Gerald would be freer, more dauntless than Bismarck.

But even as she lay in fictitious transport, bathed in the strange, false sunshine of hope in life, something seemed to snap in her, and a terrible cynicism began to gain upon her, blowing in like a wind. Everything turned to irony with her: the last flavour of everything was ironical. When she felt her pang of undeniable reality, this was when she knew the hard irony of hopes and ideas.

She lay and looked at him, as he slept. He was sheerly beautiful, he was a perfect instrument. To her mind, he was a pure, inhuman, almost superhuman instrument. His instrumentality appealed so strongly to her, she wished she were God, to use him as a tool.

And at the same instant, came the ironical question: ‘What for?’ She thought of the colliers’ wives, with their linoleum and their lace curtains and their little girls in high–laced boots. She thought of the wives and daughters of the pit–managers, their tennis–parties, and their terrible struggles to be superior each to the other, in the social scale. There was Shortlands with its meaningless distinction, the meaningless crowd of the Criches. There was London, the House of Commons, the extant social world. My God!

Young as she was, Gudrun had touched the whole pulse of social England. She had no ideas of rising in the world. She knew, with the perfect cynicism of cruel youth, that to rise in the world meant to have one outside show instead of another, the advance was like having a spurious half–crown instead of a spurious penny. The whole coinage of valuation was spurious. Yet of course, her cynicism knew well enough that, in a world where spurious coin was current, a bad sovereign was better than a bad farthing. But rich and poor, she despised both alike.

“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?”
