"Of the Surete," was the counter reply. "There are a dozen of us about here."

"When did you arrive?"

"Some two hours ago. We marched out directly after you left the orders at the Commissariat."

"You are prepared to remain on the watch all night?"

"Those are our orders, citizen," replied the man.

"You had best close up round the house, then. And, name of a dog!" he added, with a threatening ring in his voice. "Let there be no slackening of vigilance this night. No one to go in or out of that house, no one to approach it under any circumstances whatever. Is that understood?"

"Those were our orders from the first, citizen," said the man simply.

"And all has been well up to now?"

"We have seen no one, citizen."

The little party closed in around their chief and together they marched up to the house. Chauvelin, on tenterhooks, walked quicker than the others. He was the first to reach the door. Unable to find the bell-pull in the dark, he knocked vigorously.
