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 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, hollows in 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, empty 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 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 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?

“Why him? Why not us?”

“Because it was in my mind to put that little test which answered so admirably. I fear you would not have gone so far.”

The inspector smiled.

“Well, maybe not. I understand that I have your word, Mr. Holmes, that you step right out of the case now and that you turn all your results over to us.”

“Certainly, that is always my custom.”

“Well, in the name of the force I thank you. It seems a clear case, as as you put it, and there can’t be much difficulty over the bodies.”

“I’ll show you a grim little bit of evidence,” said Holmes, “and I am sure Amberley himself never observed it. You’ll get results, Inspector, by always putting yourself in the other fellow’s place, and thinking what you would do yourself. It takes some imagination, but it pays. Now, we will suppose that you were shut up in this little room, had not two minutes to live, but wanted to get even with the fiend who was probably mocking at you from the other side of the door. What would you do?”

“Write a message.”

“Exactly. You would like to tell people how you died. No use writing on paper. That would be seen. If you wrote on the wall someone might rest upon it. Now, look here! Just above the skirting is scribbled with a purple indelible pencil: ‘We we —’ That’s all.’’

“What do you make of that?”

“Well, it’s only a foot above the ground. The poor devil was on the floor dying when he wrote it. He lost his senses before he could finish.”

“He was writing, ‘We were murdered.’ ”

“That’s how I read it. If you find an indelible pencil on the body —”

“We’ll look out for it, you may be sure. But those securities? Clearly there was no robbery at all. And yet he did possess those bonds. We verified that.”

“You may be sure he has them hidden in a safe place. When the whole elopement had passed into history, he would suddenly discover them and announce that the guilty couple had relented and sent back the plunder or had dropped it on the way.”

“You certainly seem to have met every difficulty,” said the inspector. “Of course, he was bound to call us in, but why he should have gone to you I can’t understand.”

“Pure swank!” Holmes answered. “He felt so clever and so sure of himself that he imagined no one could touch him. He could say to any suspicious neighbour, ‘Look at the steps I have taken. I have consulted not only the police but even Sherlock Holmes.’ ”

The inspector laughed.

“We must forgive you your ‘even,’ Mr. Holmes,” said he “it’s as workmanlike a job as I can remember.”

A couple of days later my friend tossed across to me a copy of the bi-weekly North Surrey Observer. Under a series of flaming headlines, which began with “The Haven Horror” and ended with “Brilliant Police Investigation,” there was a packed column of print which gave the first consecutive account of the affair. The concluding paragraph is typical of the whole. It ran thus:
