They called him. No one replied.

But a soldier came running up. The gentleman had just got into a boat and was rowing away for all he was worth. The commissary looked at Gilbert and realized that he had been tricked:

“Stop him!” he shouted. “Fire on him! He’s an accomplice!...”

He himself rushed out, followed by two policemen, while the others remained with the prisoners. On reaching the bank, he saw the gentleman, a hundred yards away, taking off his hat to him in the dusk.

One of the policemen discharged his revolver, without thinking.

The wind carried the sound of words across the water. The gentleman was singing as he rowed:

“Go, little bark,

Float in the dark....”

But the commissary saw a skiff fastened to the landing-stage of the adjoining property. He scrambled over the hedge separating the two gardens and, after ordering the soldiers to watch the banks of the lake and to seize the fugitive if he tried to put ashore, the commissary and two of his men pulled off in pursuit of Lupin.

It was not a difficult matter, for they were able to follow his movements by the intermittent light of the moon and to see that he was trying to cross the lakes while bearing toward the right—that is to say, toward the village of Saint-Gratien. Moreover, the commissary soon perceived that, with the aid of his men and thanks perhaps to the comparative lightness of his craft, he was rapidly gaining on the other. In ten minutes he had decreased the interval between them by one half.
