The little man to whose help the lads had come took this in out of the tail of his eye.

"Bien! Bien!" he exclaimed, and dashed forward.

Hal and Chester were right behind him.

Hal struck out with his right, and one of the enemy toppled over with an oath. Another went down before his left fist. Chester, with a heavy blow, felled another of their opponents, and the little man, snarling and fighting with hands and feet, quickly disposed of two more.

The enemy drew back and the three had time for a breathing spell. Their foes, however, had no mind to give up the fight, and with a sudden concerted dash, surrounded the trio.

The fighting became fast and terrific. The weight of numbers was beginning to tell, and suddenly Chester went down before a heavy smash on the jaw. He was badly shaken up, but was not unconscious. As he scrambled to his feet, the clear sound of a whistle shattered the night. Immediately the fighting stopped and the assailants drew back.

"Les Gendarmes!" exclaimed one, and took to his heels, followed by the rest.

"Les Gendarmes!" exclaimed the little man to whose assistance the lads had come. "Voila!"

Chester got to his feet quickly, and, with Hal, dashed forward upon the heels of the little man. Round corner after corner, through dark streets and darker alleys he ran, the lads following close behind him. Finally, out of breath and tired of limb and body, he came to a halt in a secluded spot in a narrow street.

The lads came to a stop beside him. The man immediately threw himself upon the ground and the lads did likewise. Here, for a few moments, all lay silent, panting.
