In this chapter, we learn that Darnay's mission is to blow up the factory where Darnay is being trained. The factory is under the protection of a front company, and the guards are sound. Darnay asks if there is anything unusual about the factory, and is told that there are five key cards in the factory. He wonders who could build such a thing in secret, and wonders if the army or the big five would be able to do it. He also wonders if vermouth's warning was just a warning, like a girl who throws a fit if she just grabs her ass. He thinks that the factory's guards must be insane, and he wonders if they are going to take copies of the message Darnay has sent and run off to get revenge on the monster.
