He sat silent for a moment and continued:

"So you're quite sure that you saw Daubrecq the deputy?"

"Saw him with my own eyes, governor."

"And you know that he has an appointment in Paris?"

"He's going to the theatre."

"Very well; but his servants have remained behind at the Enghien villa... ."

"The cook has been sent away. As for the valet, Leonard, who is Daubrecq's confidential man, he'll wait for his master in Paris. They can't get back from town before one o'clock in the morning. But... "

"But what?"

"We must reckon with a possible freak of fancy on Daubrecq's part, a change of mind, an unexpected return, and so arrange to have everything finished and done with in an hour."

"And when did you get these details?"

"This morning. Vaucheray and I at once thought that it was a favourable moment. I selected the garden of the unfinished house which we have just left as the best place to start from; for the house is not watched at night. I sent for two mates to row the boats; and I telephoned to you. That's the whole story."

"Have you the keys?"

"The keys of the front-door."

"Is that the villa which I see from here, standing in its own grounds?"

"Yes, the Villa Marie-Therese; and as the two others, with the gardens touching it on either side, have been unoccupied since this day week, we shall be able to remove what we please at our leisure; and I swear to you, governor, it's well worth while."

"The job's much too simple," mumbled Lupin. "No charm about it!"

They landed in a little creek whence rose a few stone steps, under cover of a mouldering roof. Lupin reflected that shipping the furniture would be easy work. But, suddenly, he said:

"There are people at the villa. Look... a light."

"It's a gas-jet, governor. The light's not moving."

The Growler stayed by the boats, with instructions to keep watch, while the Masher, the other rower, went to the gate on the Avenue de Ceinture, and Lupin and his two companions crept in the shadow to the foot of the steps.

Gilbert went up first. Groping in the dark, he inserted first the big door-key and then the latch-key. Both turned easily in their locks, the door opened and the three men walked in.

A gas-jet was flaring in the hall.

"You see, governor... " said Gilbert.

"Yes, yes," said Lupin, in a low voice, "but it seems to me that the light which I saw shining did not come from here... "

"Where did it come from then?"

"I can't say... Is this the drawing-room?"

"No," replied Gilbert, who was not afraid to speak pretty loudly, "no. By way of precaution, he keeps everything on the first floor, in his bedroom and in the two rooms on either side of it."

"And where is the staircase?"

"On the right, behind the curtain."

Lupin moved to the curtain and was drawing the hanging aside when, suddenly, at four steps on the left, a door opened and a head appeared, a pallid man's head, with terrified eyes.

"Help! Murder!" shouted the man.

And he rushed back into the room.

"It's Leonard, the valet!" cried Gilbert.
