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 his feet found a resting-place, and 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?

Holmes gave a whimsical smile.

“I think I may safely promise that,” said he. “I may add that your problem interests me, and that I shall be prepared to look into it. How shall I keep in touch with you?”

“The Carlton Club will find me. But in case of emergency, there is a private telephone call, ‘XX.31.’ ”

Holmes noted it down and sat, still smiling, with the open memorandum-book upon his knee.

“The Baron’s present address, please?”

“Vernon Lodge, near Kingston. It is a large house. He has been fortunate in some rather shady speculations and is a rich man, which naturally makes him a more dangerous antagonist.”

“Is he at home at present?”

“Yes.”

“Apart from what you have told me, can you give me any further information about the man?”

“He has expensive tastes. He is a horse fancier. For a short time he played polo at Hurlingham, but then this Prague affair got noised about and he had to leave. He collects books and pictures. He is a man with a considerable artistic side to his nature. He is, I believe, a recognized authority upon Chinese pottery and has written a book upon the subject.”

“A complex mind,” said Holmes. “All great criminals have that. My old friend Charlie Peace was a violin virtuoso. Wainwright was no mean artist. I could quote many more. Well, Sir James, you will inform your client that I am turning my mind upon Baron Gruner. I can say no more. I have some sources of information of my own, and I dare say we may find some means of opening the matter up.”

When our visitor had left us Holmes sat so long in deep thought that it seemed to me that he had forgotten my presence. At last, however, he came briskly back to earth.

“Well, Watson, any views?” he asked.

“I should think you had better see the young lady herself.”

“My dear Watson, if her poor old broken father cannot move her, how shall I, a stranger, prevail? And yet there is something in the suggestion if all else fails. But I think we must begin from a different angle. I rather fancy that Shinwell Johnson might be a help.”

I have not had occasion to mention Shinwell Johnson in these memoirs because I have seldom drawn my cases from the latter phases of my friend’s career . During the first years of the century he became a valuable assistant. Johnson, I grieve to say, made his name first as a very dangerous villain and served two terms at Parkhurst. Finally he repented and allied himself to Holmes, acting as his agent in the huge criminal underworld of London and obtaining information which often proved to be of vital importance. Had Johnson been a “nark” of the police he would soon have been exposed, but as he dealt with cases which never came directly into the courts, his activities were never realized by his companions. With the glamour of his two convictions upon him, he had the entree of every night-club, doss house, and gambling-den in the town, and his quick observation and active brain made him an ideal agent for gaining information. It was to him that Sherlock Holmes now proposed to turn.
