“Oh!” he said as soon as he recognised the face which his friend had pointed out to him, “that is citizen Foucquier-Tinville.”

“The Public Prosecutor?”

“Himself. And Heron is the man next to him.”

“Heron?” said the younger man interrogatively.

“Yes. He is chief agent to the Committee of General Security now.”

“What does that mean?”
