There are, in many prisons, treacherous employees, half-jailers, half-thieves, who assist in escapes, who sell to the police an unfaithful service, and who turn a penny whenever they can.
On that same night, then, when Little Gavroche picked up the two lost children, Brujon and Guelemer, who knew that Babet, who had escaped that morning, was waiting for them in the street as well as Montparnasse, rose softly, and with the nail which Brujon had found, began to pierce the chimney against which their beds stood. The rubbish fell on Brujon’s bed, so that they were not heard. Showers mingled with thunder shook the doors on their hinges, and created in the prison a terrible and opportune uproar. Those of the prisoners who woke, pretended to fall asleep again, and left Guelemer and Brujon to their own devices. Brujon was adroit; Guelemer was vigorous. Before any sound had reached the watcher, who was sleeping in the grated cell which opened into the dormitory, the wall had been pierced, the chimney scaled, the iron grating which barred the upper orifice of the flue forced, and the two redoubtable ruffians were on the roof. The wind and rain redoubled, the roof was slippery.
“What a good night to leg it!” said Brujon.
An abyss six feet broad and eighty feet deep separated them from the surrounding wall. At the bottom of this abyss, they could see the musket of a sentinel gleaming through the gloom. They fastened one end of the rope which Brujon had spun in his dungeon to the stumps of the iron bars which they had just wrenched off, flung the other over the outer wall, crossed the abyss at one bound, clung to the coping of the wall, got astride of it, let themselves slip, one after the other, along the rope, upon a little roof which touches the bathhouse, pulled their rope after them, jumped down into the courtyard of the bathhouse, traversed it, pushed open the porter’s wicket, beside which hung his rope, pulled this, opened the porte-cochère, and found themselves in the street.
