The road through the river-valley was little used, and nobody came to interrupt the work. The night was dark, the sky heavy with moveless clouds.

Lupin gave the Masher and the Growler their final instructions and said, with a laugh:

"I can't tell you how amused I am at the thought of seeing Daubrecq's face when they proceed to take his scalp or slice his skin into ribbons. Upon my word, it's worth the journey."

Clarisse also had taken a seat in the boat. He said to her:

"Until we meet again. And, above all, don't stir. Whatever happens, not a movement, not a cry."

"Can anything happen?" she asked.

"Why, remember the Sire de Tancarville! It was at the very moment when he was achieving his object, with his true love in his arms, that an accident betrayed him. But be easy: I shall be all right."

She made no reply. She seized his hand and grasped it warmly between her own.

He put his foot on the ladder and made sure that it did not sway too much. Then he went up.

He soon reached the top rung.

This was where the dangerous ascent began, a difficult ascent at the start, because of the excessive steepness, and developing, mid-way, into an absolute escalade.

Fortunately, here and there were little hollows, in which his feet found a resting-place, and projecting projecting stones, to which his hands clung. But twice those stones gave way and he slipped; and twice he firmly believed that all was lost. Finding a deeper hollow, he took a rest. He was worn out, felt quite ready to throw up the enterprise, asked himself if it was really worth while for him to expose himself to such danger:

"I say!" he thought. "Seems to me you're showing the white feather, Lupin, old boy. Throw up the enterprise? Then Daubrecq will babble his secret, the marquis will possess himself of the list, Lupin will return empty-handed, and Gilbert... "

The long rope which he had fastened round his waist caused him needless inconvenience and fatigue. He fixed one of the ends to the strap of his trousers and let the rope uncoil all the way down the ascent, so that he could use it, on returning, as a hand-rail.

Then he once more clutched at the rough surface of the cliff and continued the climb, with bruised nails and bleeding fingers. At every moment he expected the inevitable fall. And what discouraged him most was to hear the murmur of voices rising from the boat, murmur so distinct that it seemed as though he were not increasing the distance between his companions and himself.

And he remembered the Sire de Tancarville, alone, he too, amid the darkness, who must have shivered at the noise of the stones which he loosened and sent bounding down the cliff. How the least sound reverberated through the silence! If one of Daubrecq's guards was peering into the gloom from the Lovers' Tower, it meant a shot... and death.

And he climbed... he climbed... He had climbed so long that he ended by imagining that the goal was passed. Beyond a doubt, he had slanted unawares to the right or left and he would finish at the patrol-path. What a stupid upshot! And what other upshot could there be to an attempt which the swift force of events had not allowed him to study and prepare?

Stackhurst held out his hand. “Our nerves have all been at concert-pitch,” said he. “Forgive what is past, Murdoch. We shall understand each other better in the future.” They passed out together with their arms linked in friendly fashion. The inspector remained, staring at me in silence with his ox-like eyes.

“Well, you’ve done it!” he cried at last. “I had read of you, but I never believed it. It’s wonderful!”

I was forced to shake my head. To accept such praise was to lower one’s own standards.

“I was slow at the outset — culpably slow. Had the body been found in the water I could hardly have missed it. It was the towel which misled me. The poor fellow had never thought to dry himself, and so I in turn was led to believe that he had never been in the water. Why, then, should the attack of any water creature suggest itself to me? That was where I went astray. Well, well, Inspector, I often ventured to chaff you gentlemen of the police force, but Cyanea capillata very nearly avenged Scotland Yard.”

When one considers that Mr. Sherlock Holmes was in active practice for twenty-three years, and that during seventeen of these I was allowed to cooperate with him and to keep notes of his doings, it will be clear that I have a mass of material at my command. The problem has always been not to find but to choose. There is the long row of year-books which fill a shelf and there are the dispatch-cases filled with documents, a perfect quarry for the student not only of crime but of the social and official scandals of the late Victorian era. Concerning these latter, I may say that the writers of agonized letters, who beg that the honour of their families or the reputation of famous forebears may not be touched, have nothing to fear. The discretion and high sense of professional honour which have always distinguished my friend are still at work in the choice of these memoirs, and no confidence will be abused. I deprecate, however, in the strongest way the attempts which have been made lately to get at and to destroy these papers. The source of these outrages is known, and if they are repeated I have Mr. Holmes’s authority for saying that the whole story concerning the politician, the lighthouse, and the trained cormorant will be given to the public. There is at least one reader who will understand.

It is not reasonable to suppose that every one of these cases gave Holmes the opportunity of showing those curious gifts of instinct and observation which I have endeavoured to set forth in these memoirs. Sometimes he had with much effort to pick the fruit, sometimes it fell easily into his lap. But the most terrible human tragedies were often involved in those cases which brought him the fewest personal opportunities, and it is one of these which I now desire to record. In telling it, I have made a slight change of name and place, but otherwise the facts are as stated.

One forenoon — it was late in 1896 — I received a hurried note from Holmes asking for my attendance. When I arrived I found him seated in a smoke-laden atmosphere, with an elderly, motherly woman of the buxom landlady type in the corresponding chair in front of him.
