There came out of the interior a stifled sneeze, the first of an uncontrollable paroxysm; another followed immediately on the heels of it; and then the driver turned with an oath, laid the lash upon the horses with so much energy that they found their heels again, and the whole equipage fled down the road at a gallop. At the first sound of the sneeze I had started back like a man shot. The next moment a great light broke on my mind, and I understood. Here was the secret of Fenn's trade: this was how he forwarded the escape of prisoners, hawking them by night about the country in his covered cart. There had been Frenchmen close to me; he who had just sneezed was my countryman, my comrade, perhaps already my friend! I took to my heels in pursuit. "Hold hard!" I shouted. "Stop! It's all right! Stop!" But the driver only turned a white face on me for a moment, and redoubled his efforts, bending forward, plying his whip and crying to his horses; these lay themselves down to the gallop and beat the highway with flying hoofs; and the cart bounded after them among the ruts and fled in a halo of rain and spattering mud. But a minute since, and it had been trundling along like a lame cow; and now it was off as though drawn by Apollo's coursers. There is no telling what a man can do until you frighten him! It was as much as I could do myself, though I ran valiantly, to maintain my distance; and that (since I knew my countrymen so near) was become a chief point with me. A hundred yards farther on the cart whipped out of the high-road into a lane embowered with leafless trees, and became lost to view. When I saw it next the driver had increased his advantage considerably, but all danger was at an end, and the horses had again declined into a hobbling walk. Persuaded they could not escape me, I took my time, and recovered my breath as I followed them.
