"Saturday. San Remo. Station platform. Give the porter of the Ambassadeurs-Palace ten francs for the loan of his cap. The three gents arrive. They speak to me. Explain to them that a lady traveller, Mme. Mergy, is going on to Genoa, to the Hotel Continental. The gents hesitate. M. Nicole wants to get out. The others hold him back. The train starts. Good luck, gents! An hour later, I take the train for France and get out at Nice, to await fresh orders."

Jacob closed his note-book and concluded:

"That's all. To-day's doings will be entered this evening."

"You can enter them now, M. Jacob. '12 noon. M. Daubrecq sends me to the Wagon-Lits Co. I book two berths in the Paris sleeping-car, by the 2.48 train, and send them to M. Daubrecq by express messenger. Then I take the 12.58 train for Vintimille, the frontier-station, where I spend the day on the platform watching all the travellers who come to France. Should Messrs. Nicole, Growler and Masher take it into their heads to leave Italy and return to Paris by way of Nice, my instructions are to telegraph to the headquarters of police that Master Arsene Lupin and two of his accomplices are in train number so-and-so."

While speaking, Daubrecq led Jacob to the the door. He closed it after him, turned the key, pushed the bolt and, going up to Clarisse, said:

"And now, darling, listen to me.

This time, she uttered no protest. What could she do against such an enemy, so powerful, so resourceful, who provided for everything, down to the minutest details, and who toyed with his adversaries in such an airy fashion? Even if she had hoped till then for Lupin's interference, how could she do so now, when he was wandering through Italy in pursuit of a shadow?

She understood at last why three telegrams which she had sent to the Hotel Franklin had remained unanswered. Daubrecq was there, lurking in the dark, watching, establishing a void around her, separating her from her comrades in the fight, bringing her gradually, a beaten prisoner, within the four walls of that room.

She felt her weakness. She was at the monster's mercy. She must be silent and resigned.

He repeated, with an evil delight:

"Listen to me, darling. Listen to the irrevocable words which I am about to speak. Listen to them well. It is now 12 o'clock. The last train starts at 2.48: you understand, the last train that can bring me to Paris to-morrow, Monday, in time to save your son. The evening-trains would arrive too late. The trains-de-luxe are full up. Therefore I shall have to start at 2.48. Am I to start?"

"Yes."

"Our berths are booked. Will you come with me?"

"Yes."

"You know my conditions for interfering?"

"Yes."

"Do you accept them?"

"Yes."

"You will marry me?"

"Yes."

Oh, those horrible answers! The unhappy woman gave them in a sort of awful torpor, refusing even to understand what she was promising. Let him start first, let him snatch Gilbert from the engine of death whose ision haunted her day and night... And then... and then... let what must come come... "

It was not a long journey from Winchester to Thor Place, but it was long to me in my impatience, while for Holmes it was evident that it seemed endless; for, in his nervous restlessness he could not sit still, but paced the carriage or drummed with his long, sensitive fingers upon the cushions beside him. Suddenly, however, as we neared our destination he seated himself opposite to me — we had a first-class carriage to ourselves — and laying a hand upon each of my knees he looked into my eyes with the peculiarly mischievous gaze which was characteristic of his more imp-like moods.

“Watson,” said he, “I have some recollection that you go armed upon these excursions of ours.”

It was as well for him that I did so, for he took little care for his own safety when his mind was once absorbed by a problem so that more than once my revolver had been a good friend in need. I reminded him of the fact.

“Yes, yes, I am a little absent-minded in such matters. But have you your revolver on you?”

I produced it from my hip-pocket, a short, handy, but very serviceable little weapon. He undid the catch, shook out the cartridges, and examined it with care.

“It’s heavy — remarkably heavy,” said he.

“Yes, it is a solid bit of work.”

He mused over it for a minute.

“Do you know, Watson,” said he, “I believe your revolver is going to have a very intimate connection with the mystery which we are investigating.”

“My dear Holmes, you are joking.”

“No, Watson, I am very serious. There is a test before us. If the test comes off, all will be clear. And the test will depend upon the conduct of this little weapon. One cartridge out. Now we will replace the other five and put on the safety-catch. So! That increases the weight and makes it a better reproduction.”

I had no glimmer of what was in his mind, nor did he enlighten me, but sat lost in thought until we pulled up in the little Hampshire station. We secured a ramshackle trap, and in a quarter of an hour were at the house of our confidential friend, the sergeant.

“A clue, Mr. Holmes? What is it?”

“It all depends upon the behaviour of Dr. Watson’s revolver,” said my friend. “Here it is. Now, officer, can you give me ten yards of string?”

The village shop provided a ball of stout twine.

“I think that this is all we will need,” said Holmes. “Now, if you please, we will get off on what I hope is the last stage of our journey.”

The sun was setting and turning the rolling Hampshire moor into a wonderful autumnal panorama. The sergeant, with many critical and incredulous glances, which showed his deep doubts of the sanity of my companion, lurched along beside us. As we approached the scene of the crime I could see that my friend under all his habitual coolness was in truth deeply agitated.

“Yes,” he said in answer to my remark, “you have seen me miss my mark before, Watson. I have an instinct for such things, and yet it has sometimes played me false. It seemed a certainty when first it flashed across my mind in the cell at Winchester, but one drawback of an active mind is that one can always conceive alternative explanations which would make our scent a false one. And yet — and yet — Well, Watson, we can but try.”
