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 which 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?

“I did not observe that.”

“No, you wouldn’t. I spotted his artificial limb. But proceed.”

“I was struck by the snaky locks of grizzled hair which curled from under his old straw hat, and his face with its fierce, eager expression and the deeply lined features.”

“Very good, Watson. What did he say?”

“He began pouring out the story of his grievances. We walked down the drive together, and of course I took a good look round. I have never seen a worse-kept place. The garden was all running to seed, giving me an impression of wild neglect in which the plants had been allowed to find the way of Nature rather than of art. How any decent woman could have tolerated such a state of things, I don’t know. The house, too, was slatternly to the last degree, but the poor man seemed himself to be aware of it and to be trying to remedy it, for a great pot of green paint stood in the centre of the hall, and he was carrying a thick brush in his left hand. He had been working on the woodwork.

“He took me into his dingy sanctum, and we had a long chat. Of course, he was disappointed that you had not come yourself. ‘I hardly expected,’ he said, ‘that so humble an individual as myself, especially after my heavy financial loss, could obtain the complete attention of so famous a man as Mr. Sherlock Holmes.’

“I assured him that the financial question did not arise. ‘No of course, it is art for art’s sake with him,’ said he, ‘but even on the artistic side of crime he might have found something here to study. And human nature, Dr. Watson — the black ingratitude of it all! When did I ever refuse one of her requests? Was ever a woman so pampered? And that young man — he might have been my own son. He had the run of my house. And yet see how they have treated me! Oh, Dr. Watson, it is a dreadful, dreadful world!’

“That was the burden of his song for an hour or more. He had, it seems, no suspicion of an intrigue. They lived alone save for a woman who comes in by the day and leaves every evening at six. On that particular evening old Amberley, wishing to give his wife a treat, had taken two upper circle seats at the Haymarket Theatre. At the last moment she had complained of a headache and had refused to go. He had gone alone. There seemed to be no doubt about the fact, for he produced the unused ticket which he had taken for his wife.”

“That is remarkable — most remarkable,” said Holmes, whose interest in the case seemed to be rising. “Pray continue, Watson. I find your narrative most arresting. Did you personally examine this ticket? You did not, perchance, take the number?”

“It so happens that I did,” I answered with some pride. “It chanced to be my old school number, thirty-one, and so is stuck in my head.”

“Excellent, Watson! His seat, then, was either thirty or thirty-two.”

“Quite so,” I answered with some mystification. “And on B row.”
