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 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?

“Well, Watson,” said Holmes with a smile, “I said it was rather whimsical, did I not? I should have thought, sir, that your obvious way was to advertise in the agony columns of the papers.”

“I have done that, Mr. Holmes. No replies.”

“Dear me! Well, it is certainly a most curious little problem. I may take a glance at it in my leisure. By the way, it is curious that you should have come from Topeka. I used to have a correspondent — he is dead now — old Dr. Lysander Starr, who was mayor in 1890.”

“Good old Dr. Starr!” said our visitor. “His name is still honoured. Well, Mr. Holmes, I suppose all we can do is to report to you and let you know how we progress. I reckon you will hear within a day or two.” With this assurance our American bowed and departed.

Holmes had lit his pipe, and he sat for some time with a curious smile upon his face.

“Well?” I asked at last.

“I am wondering, Watson — just wondering!”

“At what?”

Holmes took his pipe from his lips.

“I was wondering, Watson, what on earth could be the object of this man in telling us such a rigmarole of lies. I nearly asked him so — for there are times when a brutal frontal attack is the best policy — but I judged it better to let him think he had fooled us. Here is a man with an English coat frayed at the elbow and trousers bagged at the knee with a year’s wear, and yet by this document and by his own account he is a provincial American lately landed in London. There have been no advertisements in the agony columns. You know that I miss nothing there. They are my favourite covert for putting up a bird, and I would never have overlooked such a cock pheasant as that. I never knew a Dr. Lysander Starr, of Topeka. Touch him where you would he was false. I think the fellow is really an American, but he has worn his accent smooth with years of London. What is his game, then, and what motive lies behind this preposterous search for Garridebs? It’s worth our attention, for, granting that the man is a rascal, he is certainly a complex and ingenious one. We must now find out if our other correspondent is a fraud also. Just ring him up, Watson.”

I did so, and heard a thin, quavering voice at the other end of the line.

“Yes, yes, I am Mr. Nathan Garrideb. Is Mr. Holmes there? I should very much like to have a word with Mr. Holmes.”

My friend took the instrument and I heard the usual syncopated dialogue.

“Yes, he has been here. I understand that you don’t know him.... How long? ... Only two days! ... Yes, yes, of course, it is a most captivating prospect. Will you be at home this evening? I suppose your namesake will not be there? . . . Very good, we will come then, for I would rather have a chat without him.... Dr. Watson will come with me.... I understand from your note that you did not go out often.... Well, we shall be round about six. You need not mention it to the American lawyer.... Very good. Good-bye!”
