“All quiet in the street?”
“Yes.”
“In ten minutes I will be ready to leave. You will go also. But in the meantime if you see the least suspicious movement in the street, warn me.”
“I have my finger on the alarm-bell all the time.”
“Dubreuil, did you tell the moving men not to touch the wire of that bell?”
“Certainly; it is working all right.”
“That is all I want to know.”
The two gentlemen then descended to the apartment of Felix Davey and the latter, after adjusting the marble mantel, exclaimed, joyfully:
“Dubreuil, I should like to see the man who is able to discover all the ingenious devices, warning bells, net-works of electric wires and acoustic tubes, invisible passages, moving floors and hidden stairways. A real fairy-land!”
“What fame for Arsène Lupin!”
