"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 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 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... "

“I rather gathered that you had some idea of the sort in your head,” said he. “But why these personal attentions?”

“Because you have gone out of your way to annoy me. Because you have put your creatures upon my track.”

“My creatures! I assure you no!”

“Nonsense! I have had them followed. Two can play at that game, Holmes.”

“It is a small point, Count Sylvius, but perhaps you would kindly give me my prefix when you address me. You can understand that, with my routine of work, I should find myself on familiar terms with half the rogues’ gallery, and you will agree that exceptions are invidious.”

“Well, Mr. Holmes, then.”

“Excellent! But I assure you you are mistaken about my alleged agents.”

Count Sylvius laughed contemptuously.

“Other people can observe as well as you. Yesterday there was an old sporting man. To-day it was an elderly woman. They held me in view all day.”

“Really, sir, you compliment me. Old Baron Dowson said the night before he was hanged that in my case what the law had gained the stage had lost. And now you give my little impersonations your kindly praise?”

“It was you — you yourself?”

Holmes shrugged his shoulders. “You can see in the corner the parasol which you so politely handed to me in the Minories before you began to suspect.”

“If I had known, you might never —”

“Have seen this humble home again. I was well aware of it. We all have neglected opportunities to deplore. As it happens, you did not know, so here we are!”

The Count’s knotted brows gathered more heavily over his menacing eyes. “What you say only makes the matter worse. It was not your agents but your play-acting, busybody self! You admit that you have dogged me. Why?”

“Come now, Count. You used to shoot lions in Algeria.”

“Well?”

“But why?”

“Why? The sport — the excitement — the danger!”

“And, no doubt, to free the country from a pest?”

“Exactly!”

“My reasons in a nutshell!”

The Count sprang to his feet, and his hand involuntarily moved back to his hip-pocket.

“Sit down, sir, sit down! There was another, more practical, reason. I want that yellow diamond!”

Count Sylvius lay back in his chair with an evil smile.

“Upon my word!” said he.

“You knew that I was after you for that. The real reason why you are here to-night is to find out how much I know about the matter and how far my removal is absolutely essential. Well, I should say that, from your point of view, it is absolutely essential, for I know all about it, save only one thing, which you are about to tell me.”

“Oh, indeed! And pray, what is this missing fact?”

“Where the Crown diamond now is.”

The Count looked sharply at his companion. “Oh, you want to know that, do you? How the devil should I be able to tell you where it is?”
