At this sinister figure, Dossonville recoiled with a movement beyond his control, but recovering, he exclaimed:

"Pardon."

"It is nothing," Sanson answered flatly. "I am used to it."

"Pardon. What surprises me is this," said Dossonville, hiding his own emotion. "That you who have been imprisoned for suspected Royalist interests should expose yourself to suspicion for any cause."

"Have you not guessed my errand?" Sanson said, with a frown.

"Until you disclosed your identity, yes," Dossonville retorted sharply. "But such adventures do not necessitate a disguise at one o'clock in the night. Citoyen Sanson, had I met you otherwise, I should have nothing to say; but disguised and under a false name is different. I shall have to report it."

Sanson reseated himself.

"For thirty years I have assumed disguises and another name. Do you need to be told the reason? You yourself gave it but a moment ago,"—he paused,—"when you recoiled."

"I do not understand," Dossonville said coldly, resolved to push him to the end. "Explain fully. If I am to risk myself thus, I must know all."
