"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 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... "

Holmes withdrew, picking up his violin from the corner as he passed. A few moments later the long-drawn, wailing notes of that most haunting of tunes came faintly through the closed door of the bedroom.

“What is it, then?” asked Merton anxiously as his companion turned to him. “Does he know about the stone?”

“He knows a damned sight too much about it. I’m not sure that he doesn’t know all about it.”

“Good Lord!” The boxer’s sallow face turned a shade whiter.

“Ikey Sanders has split on us.”

“He has, has he? I’ll do him down a thick ’un for that if I swing for it.”

“That won’t help us much. We‘ve got to make up our minds what to do.”

“Half a mo’,” said the boxer, looking suspiciously at the bedroom door. “He’s a leary cove that wants watching. I suppose he’s not listening?”

“How can he be listening with that music going?”

“That’s right. Maybe somebody‘s behind a curtain. Too many curtains in this room.” As he looked round he suddenly saw for the first time the effigy in the window, and stood staring and pointing, too amazed for words.

“Tut! it’s only a dummy,” said the Count.

“A fake, is it? Well, strike me! Madame Tussaud ain’t in it. It’s the living spit of him, gown and all. But them curtains Count!”

“Oh, confound the curtains! We are wasting our time, and there is none too much. He can lag us over this stone.”

“The deuce he can!”

“But he’ll let us slip if we only tell him where the swag is.”

“What! Give it up? Give up a hundred thousand quid?”

“It’s one or the other.”

Merton scratched his short-cropped pate.

“He’s alone in there. Let‘s do him in. If his light were out we should have nothing to fear.”

The Count shook his head.

“He is armed and ready. If we shot him we could hardly get away in a place like this. Besides, it’s likely enough that the police know whatever evidence he has got. Hallo! What was that?”

There was a vague sound which seemed to come from the window. Both men sprang round, but all was quiet. Save for the one strange figure seated in the chair, the room was certainly empty.

“Something in the street,” said Merton. “Now look here, guv’nor, you’ve got the brains. Surely you can think a way out of it. If slugging is no use then it’s up to you.”

“I’ve fooled better men than he,” the Count answered. “The stone is here in my secret pocket. I take no chances leaving it about. It can be out of England to-night and cut into four pieces in Amsterdam before Sunday. He knows nothing of Van Seddar.”

“I thought Van Seddar was going next week.”

“He was. But now he must get off by the next boat. One or other of us must slip round with the stone to Lime Street and tell him.”
