"Gone!" gasped Bibot. His legs would no longer bear him. He fell backwards on to a heap of street debris and refuse, from which lowly vantage ground he contrived to give away the whole miserable tale.

"Gone! half an hour ago. Their passports were in order!… I seemed to know their faces! Citizen Marat was here…. He, too—"

In a moment the officer had once more swung his horse round, so that the animal reared, with wild forefeet pawing the air, with champing of bit, and white foam scattered around.

"A thousand million curses!" he exclaimed. "Citizen Bibot, your head will pay for this treachery. Which way did they go?"

A dozen hands were ready to point in the direction where the merry party of carriers had disappeared half an hour ago; a dozen tongues gave rapid, confused explanations.

"Into it, my men!" shouted the officer; "they were on foot! They can't have gone far. Remember the Republic has offered ten thousand francs for the capture of the Scarlet Pimpernel."

Already the heavy gates had been swung open, and the officer's voice once more rang out clear through a perfect thunder-clap of fast galloping hoofs:

"Ventre a terre! Remember!—ten thousand francs to him who first sights the Scarlet Pimpernel!"

The thunder-clap died away in the distance, the dust of four score hoofs was merged in the fog and in the darkness; the voice of the captain was raised again through the mist-laden air. One shout … a shout of triumph … then silence once again.

Bibot had fainted on the heap of debris.
