Juve paid no attention to these protestations. He went towards the corner at the farther end of the shop.

Juve knew all the dens in Paris; there was not a secret society he did not know of—societies, political and otherwise, holding mysterious meetings in these places: he knew of the existence of this trap-door and slide which led to the cellars below this library.

"We will go down to the Nihilists," said he.

Before the interested eyes of his subordinates, Juve set the trap in motion. A counter weight closed it over his head.

Juve rolled into the cellar but a few seconds after Vagualame and Bobinette had escaped from it!... To tell the truth, Juve did not know of the hidden entrance to the secret room. Dizzy from his rapid glide downwards, Juve raised his lantern. He was not surprised to find this retreat empty. He knew the slide led to second and lower series of cellars....

His eye caught a movement. The huge stack of magazines, looking as if it would topple over, so much on the slant was it, was slowly moving into an upright position again! He leaped forward, thrusting his revolver between the opening of the two portions, and prevented them from joining completely!...

What was going on behind this tricky collection of magazines, which had undoubtedly just opened to give passage to Vagualame and Bobinette?

Juve glued his ear to the fissure which marked the edge of the hidden door.... Ah!... Voices of men in discussion!... Juve could not distinguish all that the voices were saying, but a word reached his ear, clear, unmistakable—Fantômas!

He listened intently.

"You are right," remarked an invisible speaker: "It is to Fantômas we owe all these police visits and annoyances—his crimes exasperate the police—and to justify themselves in the opinion of the public they track us down more vigorously than ever!"
