will furnish a weapon against me; but no matter. The great thing is that they should be safe. You will see. They include documents of extreme importance. I entrust them to your keeping—to yours alone, Monsieur le Préfet."
"Where are they?"
"The hiding-place is easily found. All you have to do is to go to the garret above my bedroom and press on a nail to the right of the window. It is an apparently useless nail, but it controls a hiding-place outside, under the slates of the roof, along the gutter."
He moved away between the two men. The Prefect called them back.
"One second. Mazeroux, go up to the garret and bring me the letters."
Mazeroux went out and returned in a few minutes. He had been unable to work the spring.
The Prefect ordered Chief Inspector Ancenis to go up with Mazeroux and to take the prisoner, who would show them how to open the hiding-place. He himself remained in the room with Weber, awaiting the result of the search, and began to read the titles of the volumes piled upon the table.
They were scientific books, among which he noticed works on chemistry: "Organic Chemistry" and "Chemistry Considered in Its Relations with Electricity." They were all covered with notes in the margins. He was turning over the pages of one of them, when he seemed to hear shouts.
The Prefect rushed to the door, but had not crossed the threshold when a pistol shot echoed down the staircase and there was a yell of pain.
