"Here it is, said the valet, handing it to Chupin. But as the latter glanced at the address he turned deadly pale, and his eyes almost started from their sockets. For this is what he read: "Madame Paul. Dealer in Tobacco. Quai de la Seine." Great as was his self-control, his emotion was too evident to escape notice. "What's the matter with you?" asked the concierge and the valet in the same breath. "What has happened to you?"

A powerful effort of will restored this young fellow's coolness, and ready in an instant with an excuse for his blunder, he replied, "I have changed my mind. What! you'd only give me fifteen sous to measure such a distance as that! Why, it isn't a walk--it's a journey!"

His explanation was accepted without demur. His listeners thought he was only taking advantage of the need they had of his services-- as was perfectly natural under the circumstances. "What! So you are dissatisfied!" cried the valet. "Very well! you shall have thirty sous--but be off!"

"So I will, at once," replied Chupin. And, imitating the whistle of a locomotive with wonderful perfection, he darted away at a pace which augured a speedy return.

However, when he was some twenty yards from the house he stopped short, glanced around him, and espying a dark corner slipped into it. "That fool in the red waistcoat will be coming out to take the letter to that famous baroness," he thought. "I'm here, and I'll watch him and see where he goes. I should like to find out the name of the kind and charitable lady who watches over his brigand of a master with such tender care."

The day and the hour were in his favor. Night was coming on, hastened by a thick fog; the street lamps were not yet lighted, and as it was Sunday most of the shops were closed. It grew dark so rapidly that Chupin was scarcely able to recognize Florent when he at last emerged from the house. It is true that he looked altogether unlike the servant in the red waist-coat. As he had the key to the wardrobe containing his master's clothes, he did not hesitate to use them whenever an opportunity offered. On this occasion he had appropriated a pair of those delicately tinted trousers which were M. de Coralth's specialty, with a handsome overcoat, a trifle too small for him, and a very elegant hat.

"Fine doings, indeed!" growled Chupin as he started in pursuit. "My servants sha'n't serve me in that way if I ever have any."

But he paused in his soliloquy, and prudently hid himself under a neighboring gateway. The gorgeous Florent was ringing at the door of one of the most magnificent mansions in the Rue de la Ville l'Eveque. The door was opened, and he went in. "Ah! ah!" thought Chupin, "he hadn't far to go. The viscount and the baroness are shrewd. When you have flowers to send to anybody it's convenient to be neighbors!"
