The only other occupant of the first-class compartment was an elderly Englishwoman of sour aspect. Aristide, his head full of Zette and Bondon, scarcely noticed her. The train started and sped through the sunny land of vine and olive.

They had almost reached Tarascon when a sudden thought hit him between the eyes, like the blow of a fist. He gasped for a moment, then he burst into shrieks of laughter, kicking his legs up and down and waving his arms in maniacal mirth. After that he rose and danced. The sour-faced Englishwoman, in mortal terror, fled into the corridor. She must have reported Aristide’s behaviour to the guard, for in a minute or two that official appeared at the doorway.

Qu’est-ce qu’il y a?

Aristide paused in his demonstrations of merriment. “Monsieur,” said he, “I have just discovered what I am going to do to M. Bondon.”

Delight bubbled out of him as he walked from the Avignon Railway Station up the Cours de la République. The wretch Bondon lay at his mercy. He had not proceeded far, however, when his quick eye caught sight of an object in the ramshackle display of a curiosity dealer’s. He paused in front of the window, fascinated. He rubbed his eyes.

“No,” said he; “it is not a dream. The bon Dieu is on my side.”

He went into the shop and bought the object. It was a pair of handcuffs.

At a little after three o’clock the small and dilapidated hotel omnibus drove up before the Hôtel de la Curatterie, and from it descended Aristide Pujol, radiant-eyed, and a scrubby little man with a goatee beard, pince-nez, and a dome-like forehead, who, pale and trembling, seemed stricken with a great fear. It was Bondon. Together they entered the little hall. As soon as Bocardon saw his enemy his eyes blazed with fury, and, uttering an inarticulate roar, he rushed out of the bureau with clenched fists murderously uplifted. The terrified Bondon shrank into a corner, protected by Aristide, who, smiling like an angel of peace, intercepted the onslaught of the huge man.

“Be calm, my good Bocardon, be calm.”

But Bocardon would not be calm. He found his voice.
