A moment later, Mon. Gerbois appeared, and started up the street. At the end of the rue des Capucines, he turned into the boulevards, walking slowly, and stopping frequently to gaze at the shop-windows.

“Much too calm, too self-possessed,” said Ganimard. “A man with a million in his pocket would not have that air of tranquillity.”

“What is he doing?”

“Oh! nothing, evidently.... But I have a suspicion that it is Lupin—yes, Lupin!”

At that moment, Mon. Gerbois stopped at a news-stand, purchased a paper, unfolded it and commenced to read it as he walked slowly away. A moment later, he gave a sudden bound into an automobile that was standing at the curb. Apparently, the machine had been waiting for him, as it started away rapidly, turned at the Madeleine and disappeared.

“Nom de nom!” cried Ganimard, “that’s one of his old tricks!”

Ganimard hastened after the automobile around the Madeleine. Then, he burst into laughter. At the entrance to the Boulevard Malesherbes, the automobile had stopped and Mon. Gerbois had alighted.

“Quick, Folenfant, the chauffeur! It may be the man Ernest.”

Folenfant interviewed the chauffeur. His name was Gaston; he was an employee of the automobile cab company; ten minutes ago, a gentleman had engaged him and told him to wait near the news-stand for another gentleman.

“And the second man—what address did he give?” asked Folenfant.
