Both leaned back in their chairs, and their sombrely-clad figures were once more merged in the gloom of the narrow box. Instinctively, since the name of the Public Prosecutor had been mentioned between them, they had allowed their voices to sink to a whisper.

The older man--a stoutish, florid-looking individual, with small, keen eyes, and skin pitted with small-pox--shrugged his shoulders at his friend's question, and then said with an air of contemptuous indifference:

"It means, my good St. Just, that these two men whom you see down there, calmly conning the programme of this evening's entertainment, and preparing to enjoy themselves to-night in the company of the late M. de Moliere, are two hell-hounds as powerful as they are cunning."

"Yes, yes," said St. Just, and much against his will a slight shudder ran through his slim figure as he spoke. "Foucquier-Tinville I know; I know his cunning, and I know his power--but the other?"

"The other?" retorted de Batz lightly. "Heron? Let me tell you, my friend, that even the might and lust of that damned Public Prosecutor pale before the power of Heron!"

"But how? I do not understand."

"Ah! you have been in England so long, you lucky dog, and though no doubt the main plot of our hideous tragedy has reached your ken, you have no cognisance of the actors who play the principal parts on this arena flooded with blood and carpeted with hate. They come and go, these actors, my good St. Just--they come and go. Marat is already the man of yesterday, Robespierre is the man of to-morrow. To-day we still have Danton and Foucquier-Tinville; we still have Pere Duchesne, and your own good cousin Antoine St. Just, but Heron and his like are with us always."

"Spies, of course?"

"Spies," assented the other. "And what spies! Were you present at the sitting of the Assembly to-day?"

"I was. I heard the new decree which already has passed into law.

Ah! I tell you, friend, that we do not let the grass grow under our feet these days. Robespierre wakes up one morning with a whim; by the afternoon that whim has become law, passed by a servile body of men too terrified to run counter to his will, fearful lest they be accused of moderation or of humanity--the greatest crimes that can be committed nowadays."

"But Danton?"

"Ah! Danton? He would wish to stem the tide that his own passions have let loose; to muzzle the raging beasts whose fangs he himself has sharpened. I told you that Danton is still the man of to-day; to-morrow he will be accused of moderation. Danton and moderation!

--ye gods! Eh? Danton, who thought the guillotine too slow in its work, and armed thirty soldiers with swords, so that thirty heads might fall at one and the same time. Danton, friend, will perish to-morrow accused of treachery against the Revolution, of moderation towards her enemies; and curs like Heron will feast on the blood of lions like Danton and his crowd."

He paused a moment, for he dared not raise his voice, and his whispers were being drowned by the noise in the auditorium. The curtain, timed to be raised at eight o'clock, was still down, though it was close on half-past, and the public was growing impatient. There was loud stamping of feet, and a few shrill whistles of disapproval proceeded from the gallery.

"If Heron gets impatient," said de Batz lightly, when the noise had momentarily subsided, the manager of this theatre and mayhap his leading actor and actress will spend an unpleasant day to-morrow."

"Always Heron!" said St. Just, with a contemptuous smile.

"Yes, my friend," rejoined the other imperturbably, "always Heron. And he has even obtained a longer lease of existence this afternoon."

"By the new decree?"
