Be off, quickly!... If you refuse well, if you refuse, the Vorenglade letters and documents shall be reproduced to-morrow, Tuesday, morning in one of the leading newspapers. Vorenglade will be arrested. And M. Prasville will find himself in prison before night."

Lupin rubbed his hands:

"He'll do as he's told!... He'll do as he's told!... I felt that at once, when I was with him. The thing appeared to me as a dead certainty. And I found Vorenglade's address in Daubrecq's pocket-books, so... driver, Boulevard Raspail!"

They went to the address given. Lupin sprang from the cab, ran up three flights of stairs.

The servant said that M. Vorenglade was away and would not be back until dinner-time next evening.

"And don't you know where he is?"

"M. Vorenglade is in London, sir."

Lupin did not utter a word on returning to the cab. Clarisse, on her side, did not even ask him any questions, so indifferent had she become to everything, so absolutely did she look upon her son's death as an accompllshed fact.

They drove to the Place de Cichy. As Lupin entered the house he passed two men who where just leaving the porter's box. He was too much engrossed to notice them. They were Prasville's inspectors.

"No telegram?" he asked his servant.

"No, governor," replied Achille.

"No news of the Masher and the Growler?"

"No, governor, none."

"That's all right," he said to Clarisse, in a casual tone. "It's only seven o'clock and we mustn't reckon on seeing them before eight or nine. Prasville will have to wait, that's all. I will telephone to him to wait."

He did so and was hanging up the receiver, when he heard a moan behind him. Clarisse was standing by the table, reading an evening-paper. She put her hand to her heart, staggered and fell.

"Achille, Achille!" cried Lupin, calling his man. "Help me put her on my bed... And then go to the cupboard and get me the medicine-bottle marked number four, the bottle with the sleeping-draught."

He forced open her teeth with the point of a knife and compelled her to swallow half the bottle:

"Good," he said. "Now the poor thing won't wake till to-morrow... after."

He glanced through the paper, which was still clutched in Clarisse' hand, and read the following lines:

"The strictest measures have been taken to keep order at the execution of Gilbert and Vaucheray, lest Arsene Lupin should make an attempt to rescue his accompilces from the last penalty. At twelve o'clock to-night a cordon of troops will be drawn across all the approaches to the Sante Prison. As already stated, the execution will take place outside the prison-walls, in the square formed by the Boulevard Arago and the Rue de la Sante.

"We have succeeded in obtaining some details of the attitude of the two condemned men. Vaucheray observes a stolid sullenness and is awaiting the fatal event with no little courage:

"'Crikey,' he says, 'I can't say I'm delighted; but I've got to go through it and I shall keep my end up.' And he adds, 'Death I don't care a hang about! What worries me is the thought that they're going to cut my head off. Ah, if the governor could only hit on some trick to send me straight off to the next world before I had time to say knife! A drop of Prussic acid, governor, if you please!'
